The results have already proven q
success for the three years, or rather
two years in which the treatment has
been actually carried out under the di.
rection of the expert (as the first
year the spray was not applied with
full knowledge of the requirements
necessary to be effective, so that while
spraying has been done for three
years one of these years-the first

suits were futile, due to error on the
part of the owner as to strength of
the solution req1ired), in that not on

instances over 100 per cent over the
year in which the infection took place,
but the physical condition of the trees
have been improved to such an extent
that they have withstood the sapping
of their strength by insects and in

one instance, the cause of which, due

These tests were carried out under
the direction of Prof. w. w. Yothers,
chronological assistant of the United
States Department of Agriculture, Bu-

Grafton of E. H. Williams, John Nc
Cormick and w. F. Glynn, large and
successful citrus growers at Crescent
City, who, in line with the intelligent
and far-sighted growers of the State,
are quick to realize and appreciate
the value of the work of the entomol-
cgist in his special field of endeavor,
and to avail themselves of the knowl-
edge gained by his years of study and
research, in the protection of their
grove property and the eradication of
the pest that infect it.
