scarlet, crimson, terra cotta and golden shade 
brown. With the blue is included a shading 
dye which, used alone, makes a pale purple 
tint and it will make a variety of shades by 
mixing with the blue in different proportions. 
With the yellow is also a shading dye, which 
is an orange color. Green is obtained by mix- 
will fade. We have on hand lantern slides 
which were colored ten years ago, and velox 
prints which have retained the colors for nearly 
two years, and neither show any indications of 
fading. If these colors do fade, as is claimed, 
they certainly are less fugitive than some of 
the present day printing-out papers.

HUNGER IS THE BEST SAUCE 
ing blue and yellow, and a flesh tint by mixing 
orange with.a very little scarlet. We advise 
that the colors be mixed only as they are 
required for use, and that only small quantities 
be prepared at a time. 
Dissolve a little of each dye in half-ounce 
bottles, partly filled with water; then add 
acetic acid or strong vinegar until the solution 
has a decidedly sour odor, and then water 
enough to fill the bottle. The colors should 
be applied in very thin washes, which should 
be repeated until the desired strength of color 
is. obtained. To remove the colors, soak the 
print or slide in diluted ammonia until the 
color disappears; then wash thoroughly and 
try again. 
These dyes are manipulated the Same as are 
the transparent colors sold under different 
names. They produce the same effects, are 
more economical, and when misapplied are 
removed in the same manner. It is argued 
that these colors prepared from Diamond dyes 
About the time when the amateur usually 
abandons field work for the season, it is our 
intention to give more explicit directions for 
coloring. In the meantime it will be well for 
those who are interested to practice occasionally, 
even though the work may be crudely done. 
If the subjects be fruit or flowers, use speci- 
mens for guides in coloring, and get on the 
print as good a representation of the coloring 
of the original as is possible. Preserve all prints 
so colored, no matter how unsatisfactory they 
may seem. They will be useful later for 
reference, when, after a little practice, better 
work can be done.
