BOTANICAL COLLECTIONS IO/ 



ration of specimens for such a collection. 1 It may be 

 that such an herbarium would find its highest usefulness 

 as a private collection, built up to illustrate his own 

 studies by the teacher, or by his best students. To illus- 

 trate the possibilities of the plan, there are here added 

 photographs of two sheets from my own collection, one 

 ecological and one morphological (Fig. io). 2 



There is yet another important phase of herbarium- 

 making in elementary teaching. Many teachers are 

 accustomed to require from their students the making of 

 one of a definite size as an integral and important part 

 of their courses. There are many conditions under 

 which this plan seems to me of value, as when facilities 

 for any other actual work with plants are entirely want- 

 ing, or when overworked or undertrained teachers can 

 give the science but scanty attention ; and certainly it 

 gives opportunity for careful manual work which always 

 has moral value. But, viewed from the broader educa- 

 tional standpoint, the requirement of an herbarium from 

 elementary students seems to me quite uneconomical, in 



1 The fullest account of herbarium methods is contained in W. W. 

 Bailey's " Botanical Collectors' Handbook," and in Chapter X, Section IV, 

 of Gray's "Structural Botany"; there is valuable matter also in the Her- 

 barium Number of the Botanical Gazette (June, 1886); in Mr. Walter 

 Deane's series of five articles " Notes from my Herbarium " in the Botanical 

 Gazette, Vo\s. XX and XXI; and in L. II. Bailey's "Lessons with Plants," 

 p. 437. On preserving colors in dried flowers, there is a valuable note 

 in "Annals of Botany," Vol. I, p. 178. 



2 These sheets but partly illustrate the value of the plan, as they were 

 prepared as an experiment before it was fully worked out.
