have really combined in our present Director of the Labora- 

 tories a representation of the general lines of work pursued 

 by both Dr. Underwood and Dr. Gager. 



This new arrangement is specially satisfactory to our 

 Assistant Director, whose researches in mycology become 

 more and more interrupted by his administrative duties, 

 and who is often very glad to utilize the services of so excel- 

 lent a mycologist as Dr. Seaver. 



Next in importance to these rearrangements was prob- 

 ably the authorization to establish a new Garden publica- 

 tion, namely, Mycologia. Although essentially a new 

 publication, Mycologia may be regarded as a successor to 

 the Journal of Mycology, a large part of the subscription list 

 of which will come to the new publication. In the symmet- 

 rical development of botanical science in America, there 

 exists a positive necessity for such a publication, and its 

 inauguration represents one of the important functions 

 of the Garden. It is very fortunate that just at this time, 

 we should have found it possible to utilize a new cheap 

 process for the production of colored plates, so highly im- 

 portant in the illustration of fungi. 



The other publications of the Garden have appeared 

 regularly. Three parts of "North American Flora," aggre- 

 gating 255 pages, have been issued. 



Dr. Gager's paper on the effects of the rays of radium on 

 plants, comprising Volume 4 of the Memoirs, takes rank 

 among the great contributions to the subject of vegetable 

 physiology. 



Although not published under the auspices of the Garden, 

 two publications of an encyclopedic character should re- 

 ceive mention here, because of the important part which the 

 collections and library of the Garden have taken in contrib- 

 uting to their success. The first is Dr. Britton's Manual 

 of the Trees of North America; the other is the second 

 edition of the National Standard Dispensatory. 



The explorations of the year have been conducted in 

 conformity with the plan adopted by the Scientific Direc-
