The Board of Trustees of the Carnegie Institution having 

 made an appropriation of $8,000 for the establishment and 

 maintenance of a desert botanical laboratory during the fiscal 

 year 1 902-1 903, the executive committee of that institution 

 appointed Mr. Frederick V. Coville and myself as an ad- 

 visory board in relation to the undertaking. This laboratory 

 has been organized for the purpose of making a thorough in- 

 vestigation of the morphological and physiological features 

 of plants under the unusual conditions of light, humidity, 

 moisture and temperature characteristic of desert regions. A 

 resident investigator is to be placed in immediate charge of 

 the laboratory, who will carry out a series of reseaches upon 

 problems outlined by the board. This laboratory will also 

 offer opportunity to trained investigators who may wish to 

 avail themselves of its facilities to solve problems which 

 may be worked out under the conditions mentioned. My 

 duties in connection with this institution will not absorb any 

 considerable amount of my time, nor interfere with the regu- 

 lar performance of my duties at the Garden. 



The weekly conventions of botanists at the Garden have 

 been held as noted from time to time in the Journal. This 

 informal organization has proved of great value to its mem- 

 bers, as it affords a convenient opportunity for the early pres- 

 entation of the results of researches by the staff and visiting 

 investigators. 



The following persons have been granted the privileges of 

 the institution during the year for more or less extended 

 periods. A brief note is also given as to the nature of the work 

 of every person included in the list : 

 Harriet Brown Bailey.
