e film is taken from the pack it is held
between the thumb and fingers, slightly bent from top to bottom, and
slipped into its respective compartment. When all the compartments are
filled, the cage is placed in tank, which has been previously filled with
developer, the top replaced and the films left to develop for a certain
specified time. No further attention is necessary except to turn the tank
end for end, several times during the progress of development.

At the expiration of the full time, open the tank, take out the cage,
remove films, place them in a tray of water for a moment, then transfer to
the fixing bath. Development is completed. Rinse out cage and tank and set
them aside.

The operation of removing films from the pack and loading the cage is
done, of course, in a darkened room by the light of a ruby lamp. During
the day any darkened closet will suffice, at night any dark room in which
the shades are drawn will answer. To load the films in cage will take only
two or three minutes, and as soon as the top is placed on tank it may be
brought out into any light and left until development is completed. And
night is really an ideal time to develop films, as they can be fixed and
washed in a short time and will dry over night, being all ready to print
from in the morning.

If it is desired to develop less than a dozen films, one merely removes
from his pack as many films as have been exposed, places them in the cage,
and proceeds in the same manner as described above.

The cage of the No. 1 Tank is slightly different from that shown in the
illustration, but the method of loading is the same and, of course, the
results are just as dependable.
