Cross Pollination Work in 1941.—The season was unusually 
early. The first blossoms appeared on June 7, and the first nuts 
were harvested even as early as August 31. 260 hybrid nuts 
were obtained. Three new hybrids representing combinations 
new to science were obtained, making a total of 51 new hybrids

Visitors —On June 25 a delegation of about forty members of 
the Phytopathological Society of America visited the plantations.

Agricultural Experiment Station, New Haven, Conn.
