in height by eleven and a half inches in width. These dimensions 
possess the following recommendations :— 
1st,—They are simple and easily recalled to mind. 
2nd,—They are adequate for all plants which you may wish to 
put up yourself, and will include almost all mountéd specimens 
which you are likely to receive from others. The only exception 
to this that I know of, was a collection of mounted ferns, imported 
by our lamented friend Denslow from Mr. Smith, of London, whose 
sheets were an inch or two larger each way. 
3rd,—Most of the paper as found in the market can be cut up 
into these dimensions without much loss or waste. Owners of very 
large collections can order their paper direct from the manufac- 
turers, of the exact size they desire, but this is impracticable for 
small quantities, and hence the present consideration is important, 
I would remark that your stationer may tell you, that he can only 
cut certain paper, which you have selected, an eighth of an inch 
less in one of its dimensions than the size asked for ; thus, in order 
to avoid a curling or bending of the margin, it may be necessary 
to have your folded genus covers eleven and seven-eighths inches 
wide, instead of fully twelve inches, and this slight difference may 
be disregarded, as it is more than allowed for in the size of the 
eets for species. : : 
In putting up mosses, there are two plans which are sanctioned 
by different botanists. Some, like Prof. A. Gray, attach them to 
sheets of the same size as they do other plants. The advantage of 
this is, that the sheets will fit into the same pigeon holes as those 
containing the phzenogamous plants; the disadvantage 18, that, 
Since most mosses are small, a large part of the sheet will often be 
wasted room. : ; : ee 
Other botanists use smaller sheets for mosses, in which case it is 
Well to cut the ordinary genus covers and the sheets for species 
into four parts, and this will give a convenient size, and enable 
you to use the paper you have on hand. By this plan, ——— 
smaller pigeon holes or paste-board boxes will be required. Re side 
botanist must make his own choice between these two meth ser 
Some reader may like to know what quality of paper to se “6 
both for covers and sheets. I would say in reply, that I have o 
tained my paper recently from Asa L. Shipman & Son, Stationers, ee 
25 Chambers St., N. Y., who have samples of the quality of paper — 
used by Prof. Gray and Prof. Eaton, kindly furnished ~ ——
