THE HERBARIUM 



HOW TO COLLECT HEPATICS, MOSSES AND LICHENS 



Search for them in damp places at all times of the year. They 

 are so much more beautiful when in a moist atmosphere that 

 you will feel inspired to learn as much as possible about them. 

 Collect the finest specimens you find, selecting some in fruit, 

 if possible. 



Place your specimens in a convenient receptacle, box, bag or 

 basket; in such a way as to keep them separate, each specimen 

 with a few notes in pencil telling its habitat and the date and 

 place of finding. 



Clasp-envelopes, such as are used by dry-goods merchants for 

 samples, will be found particularly desirable as the mosses may 

 be dried in them and may be kept indefinitely before being per- 

 manently mounted. 



HOW TO PRESERVE HEPATICS, MOSSES AND LICHENS 



The specimens to be preserved should be laid between ab- 

 sorbent paper, under a moderate pressure until dry, then they 

 may be placed in envelopes which come for the purpose and 

 these may be glued to regular herbarium sheets or the specimens 

 themselves may be mounted directly upon sheets of paper. 



Several specimens of the same species from different localities 

 may be mounted on one sheet; but it is undesirable to put 

 different species on a sheet as this interferes with a proper 

 classification of material. 



HOW TO STUDY HEPATICS, MOSSES AND LICHENS 

 WITH THE NAKED EYE AND WITH A LENS 



Have both fresh and dry material before you for comparison. 

 If you have only dry material to start with, freshen part of it by
