FIRST ANNUAL REPORT OF THE DIRECTOR. 101 



pamphlets have been liberally bought where needed, for 

 the use of those having such work in hand. 



Aside from the instrumental equipment of the School of 

 Botany, the facilities for work now include the library col- 

 lected by Mr. Shaw, the entire botanical library of the late 

 Dr. Engelmann, the herbaria of Engelmann, Bernhardi, S. 

 B. Buckley, and Kiehl, and the private cryptogamic collec- 

 tion and pamphlet library of the Director, in addition to a 

 large number of duplicates from the Gay and Joad herbaria 

 obtained through the interest of the late Professor Gray. 



As calculated to be of historical interest in the future de- 

 velopment of the Garden, and a desirable basis for noting 

 chunges that must be made from time to time, a survey of 

 th( grounds has been made, and the results are being em- 

 bodied in two maps on a scale of twenty feet to the inch, 

 one showins: the contours for each two feet of difference in 

 elevation, as well as the general features of the garden ; 

 the other accurately locating all buildings, drains, fences, 

 beds, walks, etc., on the premises, and marking the loca- 

 tion of even the individual trees in the arboretum and else- 

 where. Such a map, though costly, is an indispensable 

 foundation for future operations in improving and develop-

 lowing areas of the various parts of the garden are ob- 

 tained: Garden proper, 9.4 acres; Arboretum, 20.5 acres; 

 Friticetum, 8 acres; Old or Vegetable garden, 3.5 acres; 

 Grove, .6 acre ; Lawn, 2.7 acres; — making a total of 44.7 

 acies. The grounds about the garden also include an equal 

 or greater acreage of pasture-land, which can ultimately be 

 usdd, wholly or in part, for extensions which may from 

 time to time be found desirable or necessary. Two large 

 green-houses, and several smaller ones, afford facilities for 

 the cultivation of exotics, and for the propagation of tender 

 and half-hardy plants used for bedding during the sum- 

 mer. 



it has been popularly supposed, and is frequently stated, 

 that representatives of all plants that are capable of cultiva-
