and efficient method of mounting most mosses, especially such as have been 
somewhat flattened while drying under slight pressure. At certain other 
times it may be more advantageous to apply the glue directly to the back of 
the specimen. 
Many bryologists have been exceedingly annoyed by the disfiguring par- 
ticles of sand or soil which rattle or rub out from the matted stems and 
rhizoids of certain mosses, when mounted on paper. This annoyance is espe- 
cially pronounced in plants which grew on sandy or clayey soil, or in such 
plants as Bruchia, and others of similar habitat, where it is desirable to 
retain, with the plant in the herbarium, a block. of clayey substatum. For- 
tunately, there is a simple method of mitigating this evil and, in most cases, 
of entirely overcoming it. After the specimen is mounted in the ordinary 
way apply a few drops of diluted white shellac to the parts which are expected 
to prove troublesome in this respect. Care should be taken to apply the 
shellac to only one side of the substratum (not to the specimen) or an unsightly 
shiny spot may be evident when the solution dries. The writer has on his 
work table a small (i oz.) reagent bottle with a rubber-topped dropping tube. 
This bottle is about half full of a mixture of shellac (i part) and 95 percent, 
alcohol (about 3 parts) which is used for the purpose mentioned. If, after 
drying, a thin film of shellac is obvious on the substratum or specimen, it is 
probably due to the fact that the shellac was not sufficiently diluted, Or else 
too much of it was used. The moral is obvious. In most cases dissections 
wiil be made from specimens left in the envelope. Sometimes, however, it 
may become necessary to dissect specimens which have been treated with 
shellac. The preliminary application of a few drops of alcohol, or even a rins- 
ing in that fluid, is then advisable. Providence, Rhode Island.
