questioned Whopper.

"Yes. The doctor wants a complete outfit, including a daylight
developing tank, and all the chemicals for developing and printing.
Then you can see what your pictures look like before you leave camp,
and if a picture doesn't suit you can take it over again."

"Not if it's a wild beast," answered Giant with a grin.

"In the case of wild animals you had better save your films or plates
until you get home. Developing in camp is not conducive to the best
work, and you might lose the very film or plate you wanted the most."

"Yes, I know something about that," said Whopper. "I once took a
beautiful picture---at least, I thought it was beautiful---of a
flock of sheep, and when I tried to develop the plate in a hurry
I got one end light-struck, so it was no good."

"Yes, and once, when I was in a hurry to develop a roll of films I
had of a military parade," said Snap, "I got the hypo in the tank
instead of the developing solution, and that was the end of that
roll."

"This is a good rule to remember," said the photographer. "Never
open the shutter of your camera until you are certain you are ready
to take the picture, and never attempt to develop a plate or a film
until you are sure your chemicals are properly mixed, and until you
are sure you have everything at hand with which to work, and until
you are sure the plate or film is properly protected from the light."
