       by  artifrcial light and developed in the dark-room the same as a dty K

waste  is scarcely a factor, has no tendency towards staining and yields
results that can scarcely be distinguishedfrom a real platinum print.
    The following unsolicitedtestimonials attest its merits and the originals

      Glass supports the  ernulsion  in  dry  plates-celluloid   in  films.
      Glass is cheaper and incomparably  easier to handle.  The  real
            difference is  in  the  emulsion.   The  unmatchable  quality
             of  the Seed plates  is  attested by  the  large  majority  of
           "           professional photographers who use them.  To do the best
          work  with  the  greatest  satisfaction and economy, follow
             their  example-buy   a  plate camera and use Seed plates.

                article, one that would give a comprehensive idea of the subject
           upon which   I propose to write.   Consequently,  I  feel that some
             explanation  is necessary in order that  I may not be accused of the
            unpardonable  sin, so frequently  committed by many  writers,  of
             deceiving my readers by the use of a misleading title.  The am-
            biguous nature of a large percentage of photographic  articles has
            impressed me very forcibly; how  their authors would never tell
            you what you thought they were going to  ; how they would seem
               to hold on to the knowledge which  they possess with  such a
selfish grip  that  they merely hover around the objective point  without  ever
reaching it.
         ''physically  By a             perfect negative"   I mean to convey the idea of one that is
free from spots, pin-holes, scratches, etc., etc. ; that is not disfigured from any
cause other than errors in exposure, development, fixation, washing, etc.   In
short, one that is as perfect when  it reaches the printing-frame as a negative as
it was when  it left the manufacturer's hands as a plat€.  This result is attained
by careful handling through the various stages of photographic manipulation,
and the presence of the imperfections enumerated is, in most cases,purely and
simply  the  result  of gross carelessness on the  part  of the  operator,  even
though he be not an expert in matters of exposure, composition and development.
  Winter  will soon be over, and the advent of Spring  will serve to infuse new
life into  all camera owners.  The  opportunity   for photographically  reproduc-
ing nature in her brightest  garb will  again be presented.  But what  is more
annoying and disappointing than  to  find  that,  despite the care exercised in
selecting a suitable subject, in adjusting the shutter speed with mathematical
precision and  in  compounding  and  proportioning  the  developer with  the
utmost accuracy, the work  has been spoiled by the appearance of  these
defects.  Ilence,  I think  this article a timely one, in as much as it will enable
you to reap the full reward which your earnest efforts have entitled you to.

  When taking a box of dry plates, of reputable make, from the store of your
 d.ealer, you can feel satisfied that such care has been taken  in  their manu-
 facture as to warrant  you in assuming that  they are in  first-class condition,
 each one capable of yielding  a perfect negative.  From  the time  the plates
 come into your possession, the responsibility of making them give such a result
 rests with you.  The manufacturer has done his part, and the degree of their
 perfection when they reach the printing-frame  as negatives is dependent upon
 the care and skill you have exercised in handling  them.  Now,  I propose to
 tell you how to perpetuate, ab it were, the care that has been bestowed upon
 them in their preparation for the market.
   Storing.-Presuming    that you have gotten your plates home safely, the first
 question that arises is where to keep them so as to avoid deterioration.  We11,
 don,t store them in your dark-room because it  is liable to be damp, and damp-
. ness is fatal to dry plates.  As gelatine plates absorb moisture, they should be
 kept in a dry room of uniform temperature with the boxes standing on edge.
 Personally,  I always take the extra precaution  of permitting  no direct light  to
 fall on the box,  although  the tripling-covering  would seem to  render  this
 unnecessary, as it is impervious to light.    Still, one cannot be too careful.       r
   Loading.-If   you have followed the ad.vice ofiered in the. last paragraph, thq
 probabilities are that the plates are still  in A-r  condition.  So we  will transfer
 ih"ot  to the dark-room and see how to handle them there without  fear of  spoil:
 ing them or impairing  their photographic value.
    First,  clean your  plateholders  thoroughly  and  carefully.  When    I  say
                                                                         ' '  , ,thoroughly                                                      I mean it in the fullest sense of the words.   Don't            and carefully,
 take any old piece of cloth, clean or dirty, and skim over the outside rapidly
 just  to  satisfy  your  conscience that you have  not  entirely  neglected  this
 important part of your work;  but remove the slides and run a camel's hair
 brush, or a piece of clean material that does not shed lint, around. the inside of the
 hold,ers,thus d.isplacingany particlesof dustthatmay havelodged there. Thengo
 over the outsid.e of the holders, and finally wipe both sides of the slides.  After
 dustingyour hold.ersin the half-hearted, slip-shod way first mentioned, you would
 probably satisfy your consciencethat you had done "something   I " now, you can
 h"n" the greater satisfaction of knowing  that the work has been done well.     I
 probably  spend. fifteen minutes  in dusting  half a dozen plate-holders, and  I
 should consider double that length of time profitably spent.
   you  will  probably  find the plates wrapped in black paper in packages of six.
  Great care should be exercised in removing  this  inside covering, as careless-
 ness might either result in undue friction by the rubbing  of the plates together,
  or scratches on the emulsion caused by the finger-nails.   With  a slow, light
  stroke, go over the plate with a camel's hair brush to remove auy particles of
  foreign matter that might have adhered to  it.   Immediate electrification of the
 nm wru take place if the brushing  is done hurriedly,  and when in this condi-
  tion  it  will attract to itself more dust than you remove.  Place the plate in the
  holder, push the slide home slowly, and  if you have followed these d.irections
  closely,1he chances are that your plate is  still  in as good coud.ition as when  it
  left the manufacturer's  hands.  For each of my plate-holders  I have made a
  bag of focusing  cloth material.   This  fits snugly and enables me to leave the





                                                                                                                                                      ...;iciir:;i

THE  C,fiTVIER&                                                               r23

              holder  in  the strongest  sunlight  without  danger  of  getting  the plates  light-
               struck, and is a precaution taken  lest by any possible chance the holders are
              not perfectly light  tight.    light  has great penetrating powers, and  I  like  to
            have that feeling of absolute safety which tends to make one more energetic in
              the prosecution  of his work.  Even  with  all this, take this  advice, don't  let
                direct sunlight  fall on your holders at any time.
              Always grasp the plate by its edges, the narrow width   if a 5 x7  or larger,
             being careful to avoid marring  the emulsion side either by  contact with  the
               fingers or finger-nails, bearing in mind that the blemishes you would thus cause
                   will be visible after the plate is developed.
             Use the extreme care I have advocated.in loading your plates, re-wrap in the
            opaque paper such of them as you have not immediate use for, close the box,
             blow out the 1amp, and the prospects of securing a good picture, as far as the
             handling of the plate is concerned, are still very bright.
               But that  is not all.  There is yet time  to ofiset by carelessness the precau-
               tionary measures you have adopted.
                Erposing.-The    next  manipulation   of  the  plate comes after you  have
             focused your camera on the  view selected and set your  shutter  at the speed
             determined upon.
                   In removing the slide be careful not to withdraw   it from the holder too sud-
              denly  or too fast, as particles  of dust  in  the cameta may be set in motion
              which,  by  settling on the plate, would form black specks and  disfigure  the
                picture.   Bear this same fact in mind. when replacing the slide after making the
              exposure, besides being sure that  it is pushed fully home before removing  the
              holder from the camera;  otherwise,  it will  furnish an excellent opportunity  for
              the light  to enter through  the aperture thus left.
               There is an important point which  I must not forget to mention before pass-
               ing on to the unloading  process. Some manufacturers  of plate-holders equip
            them  with  vulcanite  of  rubber  slides.  These are  readily  charged  with
                 electricity,   their  too rapid  withdrawal  from  the  holder  being  sufficient  to
                 electrify them.  They then act like a magnet,  attracting  dust to themselves,
             which  in turn settles upon the sensitive p1ate.   I am thoroughly convinced that
                 this  fact accounts for  the presence of many  pin-holes.    If  you are troubled
               with  imperfections of  this nature  in your  finished negative and at the same
              time are using due precaution as to cleanliness, etc., etc.,  it is more than likely
                that your slides are responsible for them,  provided,  of course, you are using
              those made of this material.  The remedy is obvious.
                 Talking  about vulcanite  of rubber  slides, I might  add that   I have known
            them to fog the plate by being withdrawn  too rapidly by the induction  of an
                 electric spark.  My  advice in a nutshell  is, don't use slides made of aulcanite
                 of rubber.
                Unloading.-We     will  continue  to  follow  the  plate and see what  care  is
               essential on  its ceasing to be such and budding  into  a negative.  We  find
              ourselves in the dark-room  again.  For  the  third  time  let me caution you
              about withdrawing  the slide slowly.   In  taking  the plate from  the holder  or
              from the developing or fixing  solutions to watch  its progress, or  in  fact at auy
               time you may have occasion to handle  it, either in its present condition or after                  ar

delicate film by the fingers or anything  else.  Another  thing, when putting
your negatives on the  drying  rack, be sure that they  fit snugly in the grooves
provided for the purpose;  otherwise, they are liable to  tilt  sideways and thus
be injured by contact with each other.
    If you have taken all the precautions suggested and you have exercised the
careful attention to details which  I have advocated, there is no reason why the
resultant negative, from a mechanical point  of view, should not be free from
mar or blemish.  As to whether  it is perfect from the standpoint  of lighting,
composition, exposure, development, fixatiou,  proper washing and drying  is
another question, one which  it is not my intention  to touch upon here.
  Just a few words in conclusion.  You may think  that  all the advice  I have
given is old., that  I have said nothing new.  Wel1, I admit this; but when you
d.o not  get the results that the following  of  this old advice would  give you,
why should any objection be raised as to its age when you rrtave not benefitted
by  it ?  This remind.s me of a 1ittle story which, though old, is appropriate.    It
was a'minister's first sermon in a church of which he had just accepted the
pastorate.  At   its conclusion, the discourse was rated excellent  by  his new
congregation, and, he was the recipient  of congratulations on  all sides.  The
following Sunday he preached the same identical sermon.  His flock evidently
stood.for  it, as nothing special was said about the repetition.   But when on the
next Sabbath day the cleric relieved himself  of the same sermon for the  third
time, one of the deacon's came up to up to him at the end of the service and
said :  "Ilow's   this  brother;  you have been here  for  three Sundays and
each time have given us the same o1d sermon ? "  The minister replied  : "That
may be true, but you are the same old sinners. "
  To be serious again.    If you are fortunate enough to get "Physically  perfect
negatives," let me congratulate you on your care and ski1l ; but  if not, and you
are sufficiently ambitious to  desire to turn out work that  is clean and perfect
from the stanclpoint under consideration, lel me ask you  to start anew and
bestow upon your plates and negatives the careful method  of handling which
I have outlined.     I am a professional now, but during my career as an arnateur
I was just as painstaking  in the directions indicated as I am now.
   First become adept in  securing "physica1ly"   perfect negatives, and then
you  will  be better equipped to grapple with  the more complex problem  of
correct development, etc.

  Some of Mr.  Eickemeyer's work  in a recent popul ar magazlne was worth
more than the price of the magazine alone to study;  yet   I  don't remember
that Mr. Eickemeyer had anything  in the Philadelphia  Salon.  Perhaps, since
his work  is not only thoroughly   artistic  but also good  photographically,     it
wouldn,t  d,o. What a capital judge  Mr. Eickemeyer would be at a Salon.
I  really wonder what he would do when he came to pronounce judgment  on
the wond.rous works  of Keiley,  White,  Day and some few  others.   Eicke-
meyer,  to my  notion,  is the representative man  in American  photography.

        N selecting apparatus, the beginner would  not do well  to emulate
              Diogines, who threw  away his earthen cup  on  seeing a man
               drink from the hollow of his hand.  A good workmad may do
              creditable work with  make-shift apparatus, but the novice must
              gain experience by use of good instruments.
               There  are, however, many appliances fitted by ingenious work-
          men to the camera, which add to  its cost yet subserve general
                    utility.      It  is needless to say such accessories are by no means
               essential.  What  is essential in a good practical working  camera
                   is,   first, a rising  or  sliding  front  board  to which  the lens is
 attaihecl,  anfl, second, a swing-back  for  securing vertical  lines when  archi-
 tectural subjects are photographed.
   First as to the "Rising  Front. "  When one wishes to take in more of the
 upper portion of the picture, that  is the sky  part, or the spires or steeples of
 buildings, the rising front, by elevating the lens above the center of  the plate,
 will enable him to include as much  of the space as may be desired, or corre-
 spondingly he may lower the front board below the center line  if   it is desirable
 to take in more fore-ground in the picture.   First-class cameras allow consid-
 erable range in this particular.
   But  just here may be the place to observe that  when much  elevation or
depression of the sliding  front  is had recourse to, care should be taken to note
whether the lens employed is sufficient in covering capacity for that portion  of
the plate drawn upon.
  Poor lenses, or lenses whose power is strained, that  is lenses designed for
smaller dimension plates than the camerato which they are attached, when
made to work on larger areas, show a falling  off in  definition where the outer
rays strike the margins of the plate in the strained quarter.
  A good lens designed for a 4x5  plate, for instance, will cover a certain area
somewhat beyond these dimensions, but when employed, soy upon an g x ro
plate, the circle of good definition,  that  is area of distinctness of image on the                                                 , t {
ground glass, is so far encroached upon,  that when the center of the plate is
shifted       up             or             down,                      the                          lens                             cannot                                 do                                           the work                                          demanded                                                                        at                                                                    the                                                                extreme                                                                                                                      jmargin.

encounter this indistinctness of definition.                                                                                                                                                                                                                                             l
  But even supposing one has a lens of good covering capacity, and yet findsthat  he has not sky enough on the ground glass to make an effective picture,                                 !,'
or  it may be that the top  of some tall  spire or tree is cut  off, even u,hen the                      :d
front  is pushed up to the highest  point.  What  is to be done ?  Naturally  the
photographer  will   tilt  his camera skyward, then upon looking  at the image on
the ground-glass, he is perplexed to find the top of the building  or spire inor-dinately  narrowed.  Perhaps he may not notice the  efiect, unless the exag-                ,1
geration is considerable, until he sees his print upon paper.
  This  apparent distortion  is due to perspective;  the lens is faithful  to the
angle of vision;  but our normal vision modifies the actual condition  of things
by calling our knowledge and judgment  to its aid.

 126                                    THE  C"&fuIER"IT

  The  Greeks used. to purposely exaggerate the top dimensions of their  tall
columns so that they did not look distorted to the eye.
    If we shall look at our camera side-wise we shall see that when so pointed
upward the back is not parallel with the  vertical line of the object.  To make
the back and of course the sensitive plate parallel with the line  of the object,
we must call into service the swing-back; one of the most important adjuncts
to the camera.   It  is a simple contrivance.
  To make use of  it so as to get the lines vertical when the camera is  tilted
upward,  all one has to do is to push it inward at the top until the desired-effect
is obtained and then clamp  it.  The swing should be made to move in both                                                                                                                                                       ';directions, that  is, backward as well as forward.                                                                           'objects
  The swing-back is not only essential to the proper representations.of
having vertical lines as in buildings, but also for photographing any view which
requires tilting  of the camera out  of the horizontal position.  For instance, a
view  of a high  mountain  like  El-Capitan,  would  have the appearance of
receding if  the caruera were tilted up.  Such a view would detract much from
the truth and grandeur of the picture.
  When the camera is directed downward to obtain a view,  there  is always
danger  of  exaggeration  of  perspective.   In  such cases the swing must be
pulled back from the vertical instead of forward.  A swing front is a feature in
some makes of cameras, but as it is but limited in use, we need not dwell upon
the application just now.  But  it should be remembered that  it can never take
the place of a swing-back.
   In another place we shall say something about discrimination  in the use of
the swing-back, and the compromise which has to be made between the abso-
 lutely true vertical and the demands of  artistic visual perspective.
   In studio cameras, that  is cameras for portraiture,  there  is a contrivance  at
the back for lateral change of  position of ground-glass and plate-carrier called
the side-swing.    It enables the operator to push in or draw out to the right  or
 left side whenever necessary.  But  elsewhere we shall enter into  particulars
about the use of  this accessory.
   In connection with the subject we would say that the shape of the bellows
 of the camera is often accountable for the cutting  off of a portion from  the
view.  Such is the case especially when the bellow's body  is conical, that is
diminished from the back forward.
  The lens-board when raised or lowered below the central liue causesthe folds
of the forward part of the bellows to abstract an inch or more from the top or
bottom of the plate, thus annoyingly  cutting  off portions  of the sky, or may
be the feet of the sitter.  These conical bellows fold up easy into a srnall com-
pass, thus adding much  to the neat and compact appearance of the camera;
but these virtues are counterbalanced by the advantages of the square bellows.
  Sometimes an extension front is placed upon a camera where the length  of .
bellows is not sufficient to accommodate for the length  of focus of lens, and it
should be borne in mind that such extensions if conical act in the same way as
a conical bellows.  Another  point to consider in choice of camera is possession
of means for front or back focus.
  For the sake of obtaining compactness the  great majority  of cameras are
made to focus from  the, front.   That  is in order to get a sharp image of the





                                                                                                                        't  i: ,.1,'t','.

            required dimensions upon the ground-glass; one is obliged, while  his head is
           under the cloth, to reach forward. and adjust the focus by moving  the bellows
            forward instead of the more simple and convenient plan of moving backwards
             or forwards the ground-glass screen.
            The back-focus contrivance to be sure adds something to the weight and
            bulk  of the camera, but   it  is more convenient  to work  and almost essential
         when the camera is used in making copies to a certain dimension.    ft requires
           a good deat  of tedious manipulation when  working   with  a front-focussing
           camera, when called upon to copy to a desired scale, necessitating the move-
          ment of the whole camera and frequent readjustment of fine focus.  But this
                is  not  the place to touch upon  the  topic  of copying,  which  will  be  fully
             treated elsewhere
             Auother  feature not  to be overlooked in the selection of a camera  is the
             adaptability  for the uses of lenses of long and short focus.  A  considerable
            lbngth of bellows is important, but  it should be so constructed that when occa-
            sion demands the folding  of  it together to a smaller compass, as when a wide
           angle short focus lens is employed,  it may be easily moved to and. fro.   fn
            adjusting the focus, the baseboard to which  the bellows  is attached being of
            considerable length,  to accommodate the length  of draw, should be so con-
             structed. as to slide inwards from the front  or hinge down  to prevent the pro-
             jecting portions from being taken  in by the lens of short focus, and forming a
            blurred or out of focus impression in the picture and cutting  off the view.
             There is a style of camera especially adapted for lenses of varying  foci, and
           which  is at the same time light and compact.
                In some varieties the long baseboard is hinged. so as to fall down in front, or
               is fastened by a screw, so that  it may be entirely removed, but such devices are
            not as good as the sliding arrangement here figured.
                In the old-fashioned cameras it was necessary to remove the focussing screen
           and. replace the slide-holder containing the plate to be exposed, but this incon-
           venience is done away with  in the improved cameras where the focussing screen
               is made an initial part of the camera and the plate-holder is introduced in front
             of  it, by the turning  of a lever controlled by springs.
          A vertical or horizontal view can also be made in the best cameras without
           removing the camera from the tripod, simply by reversing the focussing screen
          and the slides may be drawn from either side or from top or bottom.
                       It  is well to have a number of extra front boards for the placing of  different
            kinds of lenses, or the same front with metallic adapter for screwing into a gen-
             eral flange or adjuster.
            There is a speciaTizationamongst cameras; someare more peculiarly adapted
           than others to particular  kinds  of work, and one should not expect to secure
              in a single camera all the  excellencies combined.    It  is economy to employ
            special apparatus for special work, and not expect to photograph microbes and
             to copy oil paintings with the same instrument  with  which you take portraits
             or views.  The same remark applies to lenses, but more about  this presently.

                        The Ether  Saturator.

                      sp  of the drawbacks  to the use of the stereopticon,   if  the  lime-
                                 light  is needed, is the necessity of sendin g away for gas cylinders
                          every time the lantern  is used.  When  this means sending from
                          roo  to 5oo miles-as   is often the case-one  is apt to wish  to be
                         independent of the gas and express companies and still have the
                              limelight.
                             This wish can be realized if one has an Ether Saturator, and an
                        apparatus for making oxygen.
                                            rt  is proposed to give now the data for a thoroughly  safe and
                                efficient saturator;  the oxygen  apparatus  will be described later
                         if desired
              Get  two  pieces of brass tube, each 9 inches long, z inches  in  external
             diameter andtla  thick.   Ifave each end threaded and a brass cap screwed.on.
            Bore a hole in the center of each cap and tap with  /a  gas-tap.  (When   I say
        % io this paper r always mean % s^s).   Get two elbows and. a /a anion, and
            connect one end of each tube with short nipples ; in the other ends insert pillar
             cocks-the  kind which has the male thread on each end.  See diagram A.
            One of these pillar cocks should be turned so as to shape it to receive rubber
              tubing, on the end of the other should be screwed a  ,fi union.  Of this   I  will
           speak later.
           Now  the tubes need packing.   Gef some cotton  flannel-the   Leavier the
               better.  Cut a strip somewhat longer than the length of the tube, and make of
                        it a ro11that  will   fill the tube nicely, then sew  it so it  will not  unroll-it   must
             not  fit too tight.   Insert  it in the tube and cut  ofi the projecting  ends with a
            sharp knife.  Now the tubes can be connected., and the ends where the cocks
             are soldered securely together.II             To return to the use of the union named above : The Ether Saturator has two
                difficulties  :  If there is too little ether in it an excess of oxygen  is apt to enter thet             tubes and form an explosive mixture   ; not powerful enough to damage the satu-

rator, or jet, but sufficiently so to blow  off the rubber tubes and distress the
audience.    If  there should be an erccessof ether in the saturator  it  will  con-
d.ensein the tubes of the jet and flow into the rubber tubes a1so. Then one of
two things happen ; either the light  flickers and jumps, or the excess of ether
will burst through  the  orifice of  the  jet and make a blaze in and around the
lantern.  To obviate  this a condensing tube  is attached. to the saturator  by
means of the union named. above.
                                                                                                                                                                                                                                                                                                                                                                                 1
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              i  Get an ordinary bicycle hand-pump;  make a hole in the center of the screw
cap and solder in  it a /a brass short nipple, then solder the cap on.
  Next get a brass tee and attach to the nipple inserted in the cap of the hand-
pump.  Screw  in one of the remaining ends of  the tee a piece of brass pipe
turned. suitably  to receive a rubber  tube, and to the other end. attach one end
of the union with a short nipple.  See Diagram B.
  With  the aid of this attachment one can put plenty of ether in the saturator
without  fear of excess, for  if any should  liquefy   it  will  trickle  into  the con-
denser, and at the end of the exhibition  the union can be disconnected and the
collected ether poured back into the saturator.                                                                                                                                 -t
  As to filling  the saturator.  Get a taper reamer and ream out the ends of the                                                                                                                            l
cocks in the saturator  ; now get a small funnel and solder in the end of this a piece
of brass pipe which has been accurately fitted to the reamed-out holes.
  Then open both cocks and you can  fiIl with ease.  IJse sulphuric ether of  a.
good grade.   After the packing has been once saturated,  it  will take from two
to four ounces per hour for a single lantern.
  This saturator is intended for use insid.e the lantern  ; some device for securing
it inplace must be devised, while the pillar supporting the jet will come up be-
tween the two gas tubes forming the saturator.  The saturator  is placed inside
the lantern because ether  will  not vaporize  if the saturator  is cold;  the heat
from the jet being sufficient to make the ether vaporize freely.
  To connect with the cylinder:  A tee-piece must be connected with the  cyl-
inder, either by means of a rubber  tube, or, better, by being attached to the
coupling.   Connect the right side of the tee with the oxygen side of the jet by
tuears of a rubber tube.  Connect the other  side with another rubber tube to
cock in the saturator  ; while another short piece of tubing will connect the con-
densing tube with the hydrogen side of the jet.  See Diagram C.
  To start the lantern  : You  will need a stop cock on the oxygefl side of the
 iet, or a needle valve between it and the cylinder;   this must be closed till you
 get the usual flame around the lime.
  To get this:  Open both cocks in tlze saturator,'  then  turn  the gas on  at the
 cylinder, when the ether vapor will be forced through  the  jet by the pressure
 of the oxygen and can be ignited.   Get a good sized flame and warm the lime,
 then open gradually  the cock on the oxygen side of the jet,  allowing  pure
 oxygen to combine with  the ether flame until you get complete combustion.
 Generally a little more pressure from the cylinder  will be required at this stage.
 By a litt1e experimenting  the proper proportions can be ascertained and the
maximum  light obtained.
  The cost of making  this  saturator  is small,  especially if one has access to
 tools, while  it can be relied upon as a safe and efficient instrument.

                   AVE we not heard ; has  it not been told, time out  of mind, by the
                             professional photographer,  pleading as a palliative  for  his igno-
                            rance:  "Oh,    I  have no time  for experimenting.  A man  of
                           business ought  not  to squander the precious hours apportioned
                                   for  gathering  in the shekels in  trying  to find out something new
                          under  the  sun.  Leave  that  to the amateur, and   if he  lights
                             happily on anything  good, we can appropriate   it and hold   it  in
                             fee simple. "
                          Why,  there are even men in the profession who never take af;1,                      photographic magazine.  They know the whole  thing,  or  if the
                 persistent publisher gratuitously  thrusts  it upon them, condescend to read only
                the advertisements, and send for free samples of commodities recommended.
                 But  let .us pause.  Professional photography  is sometimes justified   of  its
                  ihildren  and absolved of the crime of lookiog  "askance and doubtingly"   at
                the advice so gratuitously  offered in publications.
                             , To cite a personal instance.    I have a friend-a   reputable professional-who
             was wont to spend his evenings in a convivial way  at the club where  the flow
                  of the ruddy cup stimulated the flow  of ideas.  His  festive companions were
            men of chemical-lore, and their  advice to him,  their  photographic  friend, was
              poured forth  in profuse strains of unpremeditated volubility.
              Upon a time as our acquaintance was bewailing  the persistency with  which
                the trace of  silver salt keeps its grip on the paper before toning, he received
                the last consolation that  the  effectual working  of salvation for the prints on                                                                                                                                                                                           '              such kind  of paper was to be found in sodium-chloride.
                  Discovering that this marvellous chemical was none other than the common
                kitchen sa1t, which communicated the delectable flavor to his "kartofel  sAlA.t," ,
              he procured a couple of pounds and doused it into the wash water where about.i
             one hundred beautiful prints were disporting themselves.  The result-a   ruddy',
             hue diffusing  itself over the fair  prints-and   the whole  "batch''  was suffered
                  to run violently down a steep place into the sink and were 1ost.
              Upon another occasion chloride of palladium was recommended as an inten=
                     sifier, whereupon an ounce of the  salt was purchased (standing  in business
               being excellent and credit good) and put in eight ounces of water and flowed
               over a frail looking negative without  causing a moiety  of change in its condi-
                  tion of weakness. The intensity did not come, but the  bill did  later.     I can
              assure you  it was strong enough to gratify his expenditure of "commodity  of
             good names " (?) bestowed upon the party who vouchsafed the advice.
                There came a repetition  of such experiments, for the photographer had faith,
                notwithstanding,  in his learned associates. That  gallery has disappeared from
            among the studios of light  ;  its possessorhas faded from among the children of
                the silver sunbeam.  Such experiences might  justify  the contempt of the prac-
                    tical man for theories-but  then the theorist might contend that the possession
                  of ordinary intelligence is presupposed.
