Desert Botanical Laboratory (F. V. Coville and D. T. MacDougal, 

 Washington, D. C). Grant No. 26. $8,000. 



At the meeting of the Trustees in November, 1902, a compre- 

 hensive plan for the encouragement of botanical researches was 

 submitted by the Advisory Committee on Botany (see Year Book, 

 No. 1, pages 3-12). 



In carrying out this plan, Mr. F. V. Coville, Botanist of the De- 

 partment of Agriculture, Washington, and Mr. D. T. MacDougal, 

 Director of the Laboratories of the New York Botanical Garden, 

 were requested to go to the arid lands of the west and make such 

 further recommendations as might seem to them best. They became 

 persuaded that the best position for the laboratory, considering both 

 natural and artificial advantages, is Tucson, Arizona, and they rec- 

 ommended its establishment there and the engagement of Dr. W. A. 

 Cannon to be resident investigator.
