IIO THE TEACHING BOTANIST 



trations of marked adaptations to special habits, etc., 

 must surely have a zest not inferior to the gathering 

 of all the species of a given area, though this also is 

 not to be disparaged. Moreover, a collection of this 

 kind has a practicable limit of completeness, which 

 a floristic one hardly has, and a small one expresses 

 more than a floristic one of the same size. There 

 are other plans on which herbaria may profitably be 

 made. Professor L. H. Bailey, in his " Lessons with 

 Plants ' (pp. 443-444), recommends special collections 

 and suggests various sorts. 



In making these students' herbaria, most teachers 

 require the standard size of mounting paper, the regu- 

 lar genus covers, etc. But while this size (i6|-xii-| 

 inches) is very convenient in large herbaria with 

 proper cases, one or two hundred of such sheets 

 make a package very awkward to store amongst a 

 student's other effects, and not easy to consult on 

 small crowded tables. This objection can be overcome 

 if the sheets can be reduced to the size of a large 

 book and kept stored among books. This I have 

 found to be entirely practicable, and so advantageous 

 that I have adopted it for a small private collec- 

 tion of my own, even in the presence of the best facili- 

 ties for storing the larger size. Sheets one-half the 

 usual size will hold most specimens (see Fig. 10), and 

 those too large can be treated precisely as are those 

 too large for the ordinary size of sheets. The speci-
