All of the seedlings of the above table were planted out by the 
writer in May on his land at Hamden, Connecticut. On account 
of the extremely dry summer, a considerable number died of 
drought, so that on October 1, 1932, seventy-two of the 100 were 
still living. However, all of the Winthrop and all of the Ham- 
mond hybrids came through the summer well. This fall each 
little stem was enclosed in a cylinder of 14 inch mesh wire netting 
to protect it from attack by rabbits and field mice during the 
winter. 
Other Plantings During 1932.—In early December, 1931, we 
received a quantity of nuts of various types of the Japanese chest- 
nut. These had been obtained by Dr. G. M. Reed from Japan, 
through Mr. Tanaka. Most of these germinated and are now 
growing well in the nursery north of the Laboratory Building and 
on my land at Hamden. 
Map of Chestnut Plantings—Including the hybrids, and Jap- 
anese and American trees planted there this year, there are now 
over 200 chestnut seedlings growing on this land, covering an area 
of about 3% acres. New land will have to be prepared for the 
reception this year of the additional hybrids and the seedlings of 
Castanea sativa and dentata now growing in our greenhouses. A 
map showing the location of all these plantings at Hamden is 
submitted with this ae 
Hybridization Work in 1932—During the summer Miss Rusk 
and Miss Vilkomerson pee the hybridization work, using 
only one tree, that of Mr. Renville S. Smith at Oyster Bay, L. By 
as the Japanese parent. We would like to take this opportunity 
to thank Mr. Smith for his continued interest and cordial coopera- 
tion. On June 26th and July 2d, 203 branches bearing pistillate 
flowers were castrated (i.c., stamens removed) and bagged. On 
June 27th pollen was secured from American chestnut shoots near 
New Milford, Connecticut, and on July 6th and July 10th more 
American pollen was collected from native trees near Cr afts, New 
York (not far from Lake Mahopac.) Mr. Snuth’s Japanese tree 
is peculiarly late in flowering, being practically synchronous with 
the American species or even a trifle later. On this account it 
is especially suitable for hybridizing work. As a rule the Jap- 
anese individuals bloom much earlier (sometimes several weeks ) 
than the American.
