leaves but artistic possibilities in the hands of an expert are unlimited. 
These are the essentials: 
Clear strong sunUght between ten A. M. and 3 P. M. 
Plants, flowers, grasses, preferably fresh, though dried ones may 
be used. 
Eastman's blue print paper, which may be had in rolls ten feet 
long by twenty inches wide. 
A sheet of clear glass; old window pane will do. 
Piece of pasteboard size of glass. 
Several wooden snaps (clothespins) to hold paper and glass 
together. 
Lots of enthusiasm. 
This, briefly, is the method: Gather plants, choosing finely 
divided or semi-transparent rather than solid or opaque forms. 
Lay glass on ta'ble. Arrange plant on it flat, preserving its natural 
form and making a composition by placing it well within its given area. 
Measure for size of blue print paper to cover composition. Blue 
print paper should be kept in the dark and covered with an opaque 
textile to exclude all Ught. 
Put paper face down (yellow side) on plant as it lies on glass. 
Hold in place and put pasteboard over this, fastening all together with 
snaps at four corners to prevent plant or paper from moving. 
Take outdoors in clear unobstructed sunlight and put on ground 
or bench glass side up. Watch until the yellow paper turns a grayish 
blue — several minutes. 
Carry indoors, put glass on table in original position. Remove 
snaps and lift paper without disturbing composition so another copy 
may be made if successful. 
Have large pan or sink filled with water, or better yet, hold paper 
under running water long enough (half a minute or so) to wash ofif 
yellow chemical. 
Put print with back against a glass window to drain, or put directly 
between blotters to dry and press. Blue prints do not fade if properly 
washed in clear water. 
The three points which make good blue prints better than bad 
ones are as follows: 
Do not use photographic frame which presses the plants flat and 
allows no soft edges. 
Second, the choice of plants and their arrangement in a given 
space. 
Third, place the glass at an angle of 45 degrees to the sun and not 
at right angles, which makes a flat impression, giving form alone. 
Let the sun strike the surface at a slant which will throw a shadow on 
the opposite side and soften the outlines. 
Seed forms as thick as the Great Bur or Jimson weed may be print-
