     quolity Bokelite ond is fully adjustoble to toke oll populor
      sizes of roll lilm {rom 35 mm. up to No. 116 (Zt/zx4t/4).The
     tonk should be looded in o dqrk room or chonging bog,
     but oli subsequent operotions moy be corried out in doy-
      light, since the tonk is qbsolutely light tight. The Yonkee
     Adjustoble Film Tonk hos been designed ond tested by
   men of long experience in photogrophy.  It is ruggedly
     built {or long service, qnd every precoution hos been
     token to moke it Americcl's best qnd most prccticol tonk

Irom the time you begin pouring developer into the tonk
to the time you begin pouring it out.
 When development is complete, pour out the developer
(Fig. 5) ond immediotely pour in the short stop both (or
ploin woter if ihis is recommended in the instructions  for
the developer). Let the {ilm stoy in this both lor 3 or 4
minutes. Then pour
it out ond pour in

  Fix l5 to 20 min-

TO CI.EAN TTIE TANK:
  All developers, especiolly those producing line groin,
tend to leave c deposit in the tonk. When this qccumulcr-
tion begins to become visible, it should be removed. Any
standqrd photogrcphic clecrner should be used rqther thcn
cr scouring powder which might scrqtch or roughen the
surfqce of the tonk. II the photogrophic cleqner is rubbed
on with c domp rog, it removes cll developer deposits or
stoins ond hos no elfecl on rhe surfcrce ol the Bokelite.

WHAT DEVETOPER TO USE:
  The Ycnkee Adjustcrble Film Tank con be used with cny
developing method, including physicol development, since
Bokelite does not olfect ond it is not affected by photo
chemicols. However, experience indicotes thqt most sqtis-
Ioctory results crre obtoined by those who use stondord-
formulq developers.
