The American annual of photography . oping them speed-ily and yet efficiently is an older one, except with the newerdarkroom workers to whom plates are chiefly a matter ofhistory.

It seems hardly necessary to mention formulae here beyondthe typical metol-quinol previously given, as each operatorwill probably already have hit upon the one that suits himbest. Pyro has the disadvantage for the man who does aquantity of films of leaving the fingers and finger-nails in mostunpresentable shape. With metol-quinol the difficulty is ob-viated. For those who cannot work with metol, ortol is anexcellently working reagent, quick, certain and productive ofa negative of good black color. It is, however, more expen-sive than either of the others. Pyro gives fine negatives in 288. TULIPS. ROY J. SAWYER. the tank, but so, for that matter, do the others, and above all,glycin. The time ordinarily given for tank development atdifferent temperatures may be increased ten or fifteen per centwith safety to secure the contrasty effects that seem to delightthe amateurs Speed is again a requirement when the negatives are devel-oped, washed and dried and printing is in hand. The workerwith any considerable number of prints to make will finddaylight out of the question and an artificially-lighted printer 289 a necessity. Of these there are numerous varieties, but mostof them have one fault from the standpoint of the workerfor amateurs: They permit speed when numerous prints areto be taken from one negative, but not so noticeably so whenthe negative is to be changed for each print or couple ofprints as amateur work almost exclusively demands.
