It is tt'cll to jot down important nieir.oranda at the 

 time of collecting. This is the method in ust' at the Gray 

 Herharium in (.'amliridge. It can. of course, he modified 

 to suit one's own taste oi' con\'enience. The young col- 

 lector can hegin by simjily ])ressing his specimens between 

 the leaves of a liook, tlie older and coarser the lietter; and 

 he can mount them in a lilank book designed for the ]>ur- 

 pose, or if he has only a common lilank liook, lie can cut 

 out some of the leaves, alternately with others left in ])lace, 

 as is often done with a scrap book, that when I he book is 

 full it may not be crowded at the liack. Or he can use 

 sheets of Itlank jiaper of any uniform size and mount the 

 specimens on these with gummed strips, and then group 

 them, placing those of the same genus together. Such an 

 exten)])orized herbarium, thougli crude, will serve for a 

 beginning, while stimulating his interest, and advancing 

 his knowledge of the ferns. Let him collect, ])ress, and 

 mount as many varieties as possible, giving the name with 

 date and place of collecting, etc. Such a first attempt may 

 be kept as a reminder of i)leasant hours s])ent in learning 

 the rudiments o' a delightful study.
