ring June and July, pollen of _C. dentata_ came from Mr. E.
J. Grassmann, Elizabeth, N. J., Mr. Paul Maxey, Montcoal, W. Va., Mr.
Malcolm G. Edwards, Asheville, N. C.; _C. mollissima_ and _dentata_ from
the Division of Pathology, U.S.D.A.; _C. sativa_, vars. _pistolese_ and
_selvatico_ from Dr. Aldo Pavari, _Stazione Sperimentale di
Selvicolture,_ Florence, Italy; and _C. pumila_ and _dentata_ from Mr.
Alfred Szego, Flushing, N. Y. This list is presented as evidence of the
widespread interest in our work. It is a pleasure to acknowledge this
cooperation and to thank the many donors. We are especially glad to
report that several "catches" have been made with the C. sativa scions
from France and those of the tall _mollissimas_ at Mt. Cuba, Del., from
Mr. Viggars.

May I again caution those who send us nuts not to allow them to become
dried out. The embryos, when dried, are killed. The nuts should be
wrapped in moist cotton, peat moss, or something similar, and mailed to
me not later than a few days after harvesting, at 255 South Main Street,
Wallingford, Conn.

~Insects, bad and good.~ The cankerworms were rather destructive in May at
our Sleeping Giant Plantation (not at the others) but fortunately later
than usual. The mite, _Paratetranychus bicolor_, attacked the leaves of
some of the trees on the Sleeping Giant Plantation rather late in the
season, so that on September 8 we sprayed with the Station's power
sprayer, using Aramite effectively. Shade and humidity seem to favor the
spread of this pest. Japanese beetles appeared but have never been very
destructive with us. As happened last year, we sprayed twice for the
weevils, August 14 and September 8, with excellent results.

This spring in early June, four hives of bees were placed in one of our
Sleeping Giant Plantations by bee experts of the staff of the Conn.
Expt. Station. Improved results in pollination and the resulting nut
harvest cannot be affirmed with only one season's trial.

A Method of Controlling the Chestnut Blight on Partially Resistant
Species and Hybrids of Castanea

This method has been in use since 1937 on our chestnut plantations, and
has been so remarkably successful that we believe all chestnut growers
should be thoroughly acquainted with it.
