226 MARINE BIOLOGICAL LABORATORY. 



dents. The gain was divided almost equally between investigators 

 and students, fourteen of the former and fifteen of the latter. 

 The class of beginning investigators alone showed a gain of lo, 

 i6 in 1909 as against 6 in 1908. This was one of the most 

 encouraging features of the session. We should continue our 

 efforts to increase the attendance of this class of workers, because 

 it is one of the most important functions of our Laboratory to 

 assist in the making of investigators ; and because those who are 

 to succeed us in the work of advancing our science and in the 

 management of the Laboratory are represented by the younger 

 investigators of to-day. 



Subscribing Institutions. — The number of subscribing institu- 

 tions was 19 in 1909 as against 17 in 1908; Princeton University, 

 Oberlin College, and the University of Missouri were new, and 

 we hope permanent, accessions. We are still, however, far from 

 having reached the limit of growth in this respect and we may 

 confidently expect new additions. A committee of the board is 

 now engaged in correspondence with institutions on this subject. 



Donations. — The president of the board has again provided for 

 the deficit in running expenses. He has also presented the 

 Laboratory with a large piece of land having 157 feet of frontage 

 on the main street and more than twice that on East Street, which 

 unites our two main holdings and forms an ideal site for the 

 erection of future permanent buildings. 



Supply Department. — The business of the Supply Department 

 continues to grow in a satisfactory manner; it has been neces- 

 sary to furnish Mr. Gray with two assistant collectors during the 

 year instead of one as formerly, and a bookkeeper is also employed 

 throughout the year, but the growth of the business has been 

 more than sufficient to pay for the additional expense involved. 



In conclusion, I wish to express my thanks to the board of 

 trustees for their hearty support and to the members of the staff 

 for their loyal cooperation in the work of the Laboratory.
