Mr. Alfred H. Cockayne, head of the Biological 
Division of the New Zealand government, is now in the 
United States on an important mission. He will lecture 
before the Society either in December or in January, on 
his return to California from the East. The lecture will 
deal with the native vegetation of New Zealand, and 
will be illustrated by many lantern slides. 
Prof. W. P. Tufts of the University Farm School, 
Davis, presented before the Horticultural Seminar the 
results of his experiments in regard to the pruning of 
fruit trees. Severe cutting back resulted in less devel- 
opment of root and trunk. Long pruning resulted in a 
larger tree, with correspondingly increased trunk and 
earlier fruiting. Early summer pruning was advan- 
tageous in shaping the tree, and did not reduce its vigor 
as later summer pruning did. 
The Secretary-Treasurer of the Society is Miss Anna 
E. Ehlers, 2613 Durant Ave., Berkeley. (Telephone
