CONCLUSION.

I have thus touched, gentlemen, upon a few of the many subjects that

crowd upon the mind for consideration on an occasion like this--a few

gleanings from a field which is passing rich in promise and

possibility. It is a field that some of us have cultivated for many

years and yet have only scratched the surface, and if I have ventured

to suggest or admonish, it is with the feeling that my own labors in

this field are ere long about to end and that I may not have another

occasion.

At no time in the history of the world has there, I trow, been

gathered together such a body of devoted and capable workers in

applied entomology. It marks an era in our calling and, looking back

at the progress of the past fifteen years, we may well ponder the

possibilities of the next fifteen. They will be fruitful of grand

results in proportion as we persistently and combinedly pursue the yet

unsolved problems and are not tempted to the immediate presentation of

separate facts, which are so innumerable and so easily observed that

their very wealth becomes an element of weakness. Epoch-making

discoveries result only from this power of following up unswervingly

any given problem, or any fixed ideal. The kerosene emulsion, the

Cyclone nozzle, the history of _Phylloxera vastatrix_, of _Phorodon

humuli_, of _Vedalia cardinalis_, are illustrations in point, and

while we may not expect frequent results as striking or of as wide

application as these, there is no end of important problems yet to be

solved and from the solution of which we may look for similar

beneficial results. Applied entomology is often considered a sordid

pursuit, but it only becomes so when the object is sordid. When

pursued with unselfish enthusiasm born of the love of investigation

and the delight in benefiting our fellow men, it is inspiring, and

there are few pursuits more deservedly so, considering the vast losses

to our farmers from insect injury and the pressing need that the

distressed husbandman has for every aid that can be given him. Our

work is elevating in its sympathies for the struggles and suffering of

others. Our standard should be high--the pursuit of knowledge for the

advancement of agriculture. No official entomologist should lower it

by sordid aims.

During the recent political campaign the farmer must have been sorely

puzzled to know whether his interests needed protection or not. On the

abstract question of tariff protection to his products we, as

entomologists, may no more agree than do the politicians or than does

the farmer himself. But ours is a case of protection from injurious

insects, and upon that there can nowhere be division of opinion. It is

our duty to see that he gets it with as little tax for the means as

possible.
