THE PLANT WOKLD 3 



plants, representing the natural families of Pteridopli ytes and flowering 

 plants, as comprised in the flora of the world, so far as this is possible 

 under existing conditions. Tliis collection, unlike the other, will be ar- 

 ranged approximately in the ph ylogenetic sequence of the newer school, 

 as represented, for instance, by the publications of Engler and Prentl, and 

 North American species will be admitted only Avlien families can be 

 represented in no other way. Both of these tracts are being improved 

 under landscape plans of the Olmsteds, the intention being that while 

 each is a complete synopsis in itself, the two shall blend together and 

 blend with the older part of the Garden in a harmonious way. 



Mr. Shaw, from the inception of the botanical garden idea for his 

 garden, contemplated provision for the giving of instruction. In addi- 

 tion to the facilities for instruction in pure botany afforded by the en- 

 dowment of the School of Botany and its close connection with the 

 Garden, there was a provision in his will that instruction should be 

 given to garden pupils, and a symmetrical four years' course of theoret- 

 ical and i^ractical work, covering the various branches of gardening, has 

 long been in operation at the Garden, and is each year turning out a 

 small number of men who are taking rank in the gardening i>rofession, 

 some going to the offices of landscape firms, others to the i^ractical or 

 instructional departments of agricultural colleges, others engaging 

 directly in the work of professional florists, and others becoming gard- 

 eners in private or botanical establishments, or in parks. 



For research purposes, the effort has been to primarily secure foun- 

 dation facilities. Between nine and ten thousand named species or 

 varieties of plants are annually grown in the Garden, affording a large 

 range of material from which to select plants for investigation of the 

 most varied kind. The herbarium has grown to about 350,000 incorpo- 

 rated sheets of specimens, and some 50,000 others are awaiting incorpo- 

 ration. The scientific value of the collections of both living and dried 

 plants may be gathered from the statement that the former contains 

 much material derived from Engelmann and representing the original 

 sources of many of his conclusions on cacti, agaves, yuccas, etc., as well 

 as the living material on which important investigations have been made 

 at the Garden within recent years, the living type collections of cacti of 

 Mrs. Katharine Brandegee, etc. ; while the latter contains the herbaria 

 of Bernhardi, Engelmann, Redfield, Chapman, Jorr, Jermy, Eiehl and 

 others who have done work of either local or general value, as well as 

 large numbers of types and other material subjected to recent critical 

 examination by the Garden staff or other botanists. 



The library, which now comprises some 15,000 volumes and 19,800 

 pamphlets, is especially rich in the earlier authors' separates derived 

 from the Engelmann library and other sources, and in sets of long series
