Saston I received from Rolf© a complete set of camera lucida draw¬ 
ings of the Kew types of a genus in which I was very much interested. 
Your promise of specimens is delightful. Whatever you send to 
ate will he treasured and serve & useful purpose. In making specimens 
it is al/ays well to include foliage.as flowers are, by themselves, 
very unsatisfactory. If dipt in boiling water for & few minutes ojfe 
if subjected to heat the fleshy parts of orchids dry very well and 
the leaves adhere better to the stems. The flowers should not be 
put in water, but a little experience in the application of heat 
through several thicknesses of thifek blotting paper with an ordin¬ 
ary flat-iron will enable you to keep the colors pretty well. Rotes 
as to color, outline sketches of foliage where it is inconvenient 
to spare actual material are most useful, and then any notes as to 
locality and time of collecting are necessary to make a specimen 
botanically good. 
When you receive the model herbarium specimen you asked for 
you will note that each genus is given a special cover with the 
name of the genus at the lower left hand corner on the outside. 
The number of the genus is placed first, and the genus covers are 
filed in cases of the proper siae, according to the numerical 
sequence adopted. A card catalogue of the genera aphabetically 
will make it possible to turn to any given genus . If you 
wish any more information as to herbarium methods please let me 
give it to you. 
By this time my set of Orchidacea© must have- reached you. If 
by any chance It goes astray another set will be forwarded at once. 
Yds. 4,5 and 6 are very beautiful specimens of printing and for 
that reason should be of interest for you if botanically they fall 
outside the realm of your immediate interests. 
Yours very sincerely.
