spite the attention paid to research in these subjects in Govern- 
ment agricultural bureaus, state experimental stations, and special 
research institutes, much more should be done. 
The increase in the last quarter century of our general knowl- 
edge of heredity presents a basis for rapid advance along the lines 
of many specific biological problems involving matters of inherit- 
ance. The tremendous practical importance of an intensive 
knowledge of plant breeding and plant protection to this country 
of rapidly increasing population, with a consequent growing im- 
portance of the food problem, is obvious to any thoughtful person, 
Too much scientific work cannot be done along this line; nor too 
much money made available for this work. 
Very sincerely yours,

Dear Dr. Gager: 
The fear that work in science may be duplicated, when a new 
agency enters the field, is an unconscious expression of the feel- 
ing that there exists in nature a definite sum of knowledge to be 
uncovered and that when one fact is subtracted there remains that 
much less to investigate. But there is no such limit. The un- 
covering of one fact or phenomenon only discloses another. 
There are no remainders. The field is limitless. If ten times 
the present researches in plant breeding, diseases, and other lines 
were now to be instituted, we should still be touching only the 
borders of the unknown. Plant breeding is not one subject, but 
a congeries of a thousand and one problems. No two persons are 
likely to attack the same identical problem or in the same way. 
This may be said of any other field to which we happen to have 
given a name. We need many minds under different environ- 
ments trained on all the problems of science. There need be no 
fear of duplication in research in any field. We shall never have 
enough of it. | 
I hope you will be able to assemble your endowment and to
