extent, and I have great faith in its efficacy. Herein we see 

 another possibility of development realizable only through 

 instruction. 



But it is as important for independent investigators as for 

 beginners to cultivate organic unity in their work. How shall 

 the investigator hope to keep in touch with the multiplying 

 specialities of his science .-' Here again I maintain that in- 

 struction is an indispensable means. Fill a laboratory with 

 investigators and, if no instruction is provided, many of the 

 more important avenues of acquisition will be closed and the 

 opportunities for coordination of work will be of little or no 

 avail. Investigators might work for months in adjoining rooms 

 and never learn anything about each other's work, as every one 

 knows who has worked in such a laboratory. How different 

 in a laboratory where instruction is so arranged as, without 

 overtaxing any one, to bring the workers into active and mutu- 

 ally helpful relations, and enable them to draw from one an- 

 other the best that each can give ! Instruction in the various 

 forms before indicated supplies just the conditions most favor- 

 able to interchange of thought and suggestion. It is just this 

 feature of our work at Wood's Holl to which we are most 

 indebted for whatever success we have had. 



I am aware that other points might be raised, but it is far 

 from my purpose to run down all possible objections. It is 

 enough to have indicated the grounds of my choice of types. 

 It now remains to briefly sketch the general character and to 

 emphasize some of the leading features to be represented in a 

 biological station. 



The first requisite is capacity for growth in all directions 

 consistent with the symmetrical development of biology as a 

 whole. The second requisite is the union of the two functions, 

 research and instruction, in such relations as will best hold the 

 work and the workers in the natural coordination essential to 

 scientific progress and to individual development. It is on 

 this basis that I would construct the ideal and test every prac- 

 tical issue. 



A scheme that excludes all limitations except such as nature 

 prescribes is just broad enough to take in the science, and that
