Cirowing in damp shady hollows and along streams, also on

 issued as M. sttbglobosum No. 33 by Mr. Holzinger. Mr. Williams 

 sent me this species with a drawing and description in i 897, dedicated 

 to me, but in order to do justice to Mr. Holzinger, who has also 

 recognized the differences between it and its allies, we ha\e adopted 

 his name with his consent. We offer about two dozen specimens 

 at se\'en (7 cts.) cents apiece wich printed labels. Address. R. S.

HOW TO MOUNT MOSSES. 



THE most artistic way of mounting mosses is to glue the spec- 

 imens to small cards, which can be fastened to regular 

 herbarium paper, or perhaps it will be found more satisfac- 

 tory to glue directly to the herbarium sheet. Mr. C. (".. Pringle 

 mounts his on cards, as does Dr. John K. Small, who has the neatest 

 appearing collection of mosses the editor has ever seen. .An ideal 

 way would be to ha\'e a duplicate of each glued specimen in an 

 envelope beside it for study, so that the appearance Wi^taX not be 

 spoiled by breaking off bits for microscopic examination. llowe\er, 

 I do not know of any collection thus arranged. The great majority 

 of moss collectors simply inclose the specimen in an enxelojie made 

 for the purpose, and glue the envelope to the herbarium sheet, 

 putting the label on the outside of the einelope. There are se\"eral 

 styles of envelopes in use, one a rectangular piece of paper folded 

 across so that the lower edge reaches within an inch or so of the 

 upper edge. This edge is then folded down and the ends folded 

 under. The only of^jection to this style of envelope is the time 

 needed to open and refold the envelope for the examination of 

 the specimen. These en\elopes should be of different sizes to fit 

 the size of the specimen. 



Many use half-size herbarium paper, 1 1 !^ by 8.' 1, and I shoukl 

 recommend this for amateur work, unless a large collection is 

 plaiuied. If there are only one or two specimens of each sjiecies 

 thev look lonesome on a tu'l-size sheet, to say nothing ot wasted 

 space and increased cost. Personally, however, I greatK regret 

 that I began mounting m\- collection on small sheets.
