4 MOSSES WITH A HAND-LENS 



four hours, and then remove and dry thoroughly in the open air. 

 Mosses growing in thin mats are best spread out in the drying 

 papers in their natural position, care being taken to remove any 

 surplus of adherent substratum, soil, rotten wood, etc., also any 

 other species that may be intertangled with the one it is desired 

 to collect. If the mats are thick and consist principally of erect 

 stems, it is better to break them up into vertical sections or 

 slices before pressing. The substratum, the habitat, the locality, 

 the date, and the name of the collector should be noted for each 

 specimen, and either put in with the specimens or else recorded 

 in a note-book, numbered to correspond to numbers attached to 

 the specimens. The name of the person identifying the plant 

 should also be written on the label. Many times it is also im- 

 portant to give the altitude at which the specimens were col- 

 lected. The following is a good sample label:

Pseudoleskea rigescens (Wils.) Lindb. 



Bark of Alder Trees. Alt. i, 800 ft. 



Beaver Meadows, Vancouver, Id., Aug. 26, 1901.

When dried the mosses may be placed in suitable envelopes or 

 pasted on cards, and preserved in an herbarium in the usual manner. 



In the pronunciation of the scientific names it is well to re- 

 member that the best authorities give the English pronunciation 

 of the Latin with the accent according to the rules of Latin gram- 

 mar. The Roman pronunciation so much in vogue in schools and 

 colleges is sure at some early date to supersede the English, but 

 at present the English has the weight of authority. 



The pronunciation is indicated by the same signs as in the re- 

 cent works on the flowering plants. 



\ Indicates the accent and the long, broad, open, or close 

 English sound of the vowel. 



'Indicates the accent and the short English sound.
