CO-OPERATION.

Every other subject that might be considered on this occasion must be

subordinate to the one great question of co-operation. With the large

increase of actual workers in our favorite field, distributed all over

the country, the necessity for some co-operation and co-ordination

must be apparent to every one. Just how this should be brought about

or in what direction we may work toward it, will be for this

association in its deliberations to decide. Nor will I venture to

anticipate the deliberations and conclusions of the special committee

appointed to take the matter into consideration, beyond the statement

that there are many directions in which we can adopt plans for mutual

benefit. Take, for instance, the introduction and dissemination of

parasites. How much greater will be the chance of success in any

particular case if we have all the different station entomologists

interested in some specific plan to be carried out in co-operation

with the national department, which ought to have better facilities of

introducing specimens to foreign countries or to different sections of

our own country than any of the State stations.

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 larvæ 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. The station entomologist may be engrossed in some line of

research which he deems of more importance to the people of his State,

and may resent being called upon to divert his energies; and with no

central or national power to decide upon plans of co-operation for the

common weal, we are left to voluntary methods, mutually devised, and

it is here that this association can, it seems to me, most fully

justify its organization. And this brings me to the question of
