supplied. Its natural setting makes it one of the show places 

 of the Garden. 



Considerable time has also been devoted to plans and accumu- 

 lations of material looking toward the development of facilities 

 for educational and research work in economic botany at the 

 Garden. This involves lantern slide material for lectures, 

 exhibit material, and living greenhouse and outdoor material. 



As for several years past, I have been editor of the Genetics 

 Section of Botanical Abstracts, which involves the editing, 

 abstracting, and securing abstracts of several hundred genetic 

 papers and books annually. 



Part of my time, during the forepart of the year, was taken up 

 with the preparation of "The Amazon Valley" section of 

 The Naturalist's Guide, a work now in press. This work is to 

 be issued as a guide for naturalists and others, and covers North 

 America, Central America, the West Indies, and northern South 

 America. 



Numerous inquiries regarding heredity, plant-breeding, eco- 

 nomic plants, and South America were answered. 



Respectfully submitted,

 Curator of Plant Breeding 



and Economic Plants, 



REPORT OF THE HORTICULTURIST AND HEAD 

 GARDENER FOR 1924 



Dr. C. Stuart Gager, Director. 



Sir: I beg to submit herewith my report for the year ending 

 December 31, 1924. 



The gardening force consisted of six gardeners. Half the 

 time of one man was assigned to the Curator of Elementary 

 Instruction and half the time of one man to the Curator of 

 Plant Pathology. During the growing season two men from 

 the laboring force were available for gardening work. With 

 the increase of the scientific collections and of the horticultural 

 features of the garden the services of two additional gardeners are 

 urgently needed.
