r Sleeping Giant
Plantation and from these were obtained 247 nuts. Finally, we have this
year succeeded in making a cross between _Castanea henryi_, the Henry
Timber Chinkapin from southern and central China, which is said to
attain a height of 90 feet, and _C. mollissima_, the Chinese chestnut.
Since _henryi_ blooms very early, much before our _mollissima_, the
Division of Forest Pathology mailed us pollen of _C. mollissima_, which
reached us just in time to be applied to _henryi_. Seven good nuts of
this cross were gathered.

Altogether, as the overall result of our cross pollination work, we
harvested 1259 nuts, more than twice as many as obtained in any other
year since we began this work in 1930.
