SOME SUMMER USES FOR BLUE PAPER.

Blue paper is so easily made, and the materials are so cheap, that one
can use a great deal of it and still not go to much expense.

Nothing is better for a photographic outing than the blue paper. The
materials can be carried dry and made up as needed, all that is
necessary being to mix them with clear water. Any good unglazed paper
can be used for the solution, though, of course, the photographic papers
are the best.

Blue prints do not curl or exhibit any of the disagreeable traits of
other sensitive papers, and therefore are specially fine to illustrate
letters or journals, and being so cheap can be used profusely.

Letter-paper may be sensitized, and a picture printed at the top, making
a very attractive and original letter-head. Use unglazed writing-paper,
and sensitize a strip at the top a little larger than the picture to be
printed on it. As all the sensitizing solution not exposed to the light
washes off when placed in water, cover all parts of the paper to which
it has been applied while printing. After printing put the whole sheet
in the water and wash till clear. After it is washed, blot off the
superfluous moisture, and place the prints between clean sheets of white
paper, and put them under a press till dry. A letter-press is the best,
though it must not be screwed down too tight. Several heavy books, a box
half full of stones, or a smooth board with several stones laid on top
make good presses.

Impressions of wood treasures may be taken on blue-print paper. The
printing-frame must have a clear glass which just fits it. On this clear
glass lay whatever flower, leaf, spray of which you desire to make the
outline. Put a sheet of blue paper over it, and expose to
