’ ENTOMOLOGICAL AND BOTANICAL DIVISION.
As heretofore, under the direction of Prof. Garman, forage
plants have been given a large share of attention in this division
during the year. The plots on the new addition of the Experiment
Farm are aifording a better opportunity of testing the various A
species of plants adapted in one way or another to furnish food
for stock. Co-operative work in forage plants has been continued
with the U. S. Department of Agriculture. We have now 173 plots
on the Experiment Farm used in this connection, and Prof. Gar-
man reports that we have now on hand for this spring’s planting
the finest assortment of annual forage plants that has been seen
in the State. _
Mr. W. G. Campbell has been employed to assist Prof. Garman
in this co—operative work. The U. S. Department of Agriculture
appropriated $500.00 towards such experiments for the hscal year.
This is used in part payment of Mr. Campbell’s salary and in labor.
Experiments with the Hessian fly have been continued, and a
bulletin, No. 103, has been published giving the results obtained
in these experiments. The experiments still continue. A
`· Experiments in spraying cabbage and tobacco with arsenites
were carried out in the plots on the farm during the year. The
study of insects injurious to grains and seeds has been continued.
Grape insects have been given attention. In the line of fungus
I troubles, a knot disease on young apple trees has been investigated.
