SCIENTIFIC RESEARCH 
AN UNLIMITED FIELD 
‘The fear that work in science may be duplicated, 
when a new agency enters the field, is an unconscious 
expression of the feeling 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 
uncovering 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 i in any field. 
We shall never have enough of it
