bind the books up by means of raffia in covers of 
thicker paper and of attractive colors, having 
covers about twelve and a half inches long by six 
and a quarter inches wide and then folding them 
in the middle. 
You can get some interesting illustrations for 
your wild flower booklets, especially of the leaves 
of the wild flowers, by making prints on blue-print 
paper, or better on van Dyke Solar paper. Such 
prints are very attractive and will add much to the 
interest of your booklets. 
It will also be worth while to press some of 
the smaller and more attractive of the common 
flowers and mount them upon the sheets of which 
your booklets are made, so that these pressed 
specimens will be a part of the completed book- 
let. For pressing such flowers very likely it Will 
be possible to obtain some of the thick botani- 
cal drying paper, which can be purchased of 
any dealer in school supplies, but if this is not 
available blotting paper or even newspapers will 
answer very well, and many of the smaller speci- 
mens may be readily pressed between the leaves 
of a book, choosing some old book in which the 
paper is porous. Your success in drying these 
specimens so that the colors do not fade will de- 
pend very largely upon how often you change the 
dryers. You can get especially good results by 
using dryers which have been heated near a radia-
