On the west slope sphagnum is found occasionally also in wet places in the 

 deep woods, but not in great abundance. 5. teres was collected in a meadow at 

 Granite Park, just at timber line. In wet meadows above timber line, at Iceberg 

 Lake and Sperry Glacier, 5. Girgensohnii Russ. was found in some abundance. 



The writer is indebted to Dr. A. LeRoy Andrews for the determination of 

 the species enumerated. The specimens were gathered only incidentally, and 

 doubtless an experienced bryologist could have discovered a larger number of 

 species.

MOUNTING MOSSES FOR EXHIBITION PURPOSES 



Elizabeth M. Dunham 



In an exhibition of specimens the desired effect on the observer may be 

 gained or lost by a careful or a careless method of arrangement. 



The usual way of mounting mosses in envelopes for the herbarium is not at 

 all suitable for exhibition purposes. People will not take the time and trouble 

 necessary to open the envelopes in order to examine the specimens. Mosses 

 dried in the natural condition without being pressed, and placed in small boxes, 

 are at once attractive and interesting, but very inconvenient to carry around 

 without injury. Pressed specimens may be stuck in sheets of heavy paper or 

 cardboard, and be either hung so as to be seen to good advantage or placed on 

 tables where they can be handled easily; but after awhile in this case they be- 

 come broken from rubbing against each other. 



After trying to exhibit mosses in these various ways the following method 

 of mounting has proved most satisfactory both to the observer and to the exhibi- 

 tor. I select a good specimen that has been pressed only slightly and without 

 destroying the natural characteristics more than necessary. This is stuck on a 

 cardboard about x 7 inches in size, preferably gray in color, just dark enough 

 not to show fingerprints too easily, and with a surface smooth enough for writing. 

 The moss should be placed toward the top or to one side of the card, to leave 

 space for the name and a brief description giving habitat and pointing out leading 

 characteristics. The specimen is protected by a piece of the thinnest celluloid, 

 cut a little larger, which can be easily sewed to the cardboard through holes 

 punched with a large needle. If, in course of time the moss becomes too faded to 

 look well it may be changed easily for new material and the same cardboard and 

 celluloid used again. 



The cardboard and celluloid may be bought in large sheets and cut to the 

 desired size. This method of mounting mosses has proved attractive and in- 

 structive to both children and adults; the mounts are very durable and are easily 

 carried around and handled without injury to the specimen; and it requires only 

 a little time and patience, without much skill or expense, to prepare them.
