Let us suppose that the fruit growers of one section of the country,
comprising several States in area, need the benefit in their warfare
against any particularly injurious insect of such natural enemy or
enemies as are known to help the fruit growers of some other section.
There will certainly be much greater chances of success in the
carrying out of any scheme of introduction if all the workers in the
one section may be called upon through some central or national body
to help in the introduction and disposition of the desired material
into the other section. Or, take the case of the boll worm
investigation already alluded to. The chances of success would be much
greater if the entomologists in all the States interested were to give
some attention to such lepidopterous larvae as are found to be affected
with contagious diseases and to follow out some specific plan of
cultivating and transmitting them to the party or parties with whom
the actual trials are intrusted. The argument applies with still
greater force to any international efforts. I need hardly multiply
instances. There is, it is true, nothing to prevent any individual
station entomologist from requesting co-operation of the other
stations, nor is there anything to prevent the national department
from doing likewise; but in all organization results are more apt to
flow from the power to direct rather than from mere liberty to request
or to plead.
