stratum, or substance it was growing upon, and the date of collect- 

 ing, should be written on tlie flap that folds down. The packets 

 should be cut of various sizes to accommodate differently shaped 

 specimens, and the paper should be rather stout. It is well to 

 have stock patterns of a few of the most useful sizes of packets 

 cut out of stiff paper, for the purpose of obtaining the outline on 

 the paper used for making packets. By marking the outline of the 

 pattern on the top sheet of a pile of paper, a number of packets

 fairly heavy quality. Never stick more than one species on the 

 same sheet, which in the case of small specimens may perhaps take, 

 say four packets of the same kind of fungus collected in different 

 localities, and at different dates. The advantage of liaving several 

 examples of the same fungus is, that each specimen frequently 

 shows some particular feature better than any of the others. When
