No thinning of twigs or small branches was done on any part of the tree during the first four Fig. 3.—Mission tree 5 years old which has been shaped by light annual priming. Illustrates system C after pruning in 1929. A light crop was borne the fifth season. The following winter the trees were opened up by removing all of the main branches except four, five, or six scaffold branches on each tree. These reserved branches were selected so as to form as nearly as possible a hollow inverted cone with sides rising at an angle of about 60 degrees from the horizontal. After the removal of superfluous large branches, the lower half of the tree was thinned out by the removal of twigs or by cutting back to laterals as much as appeared necessary to prevent overbearing. No topping of the main branches was done. (See figs. 1 and 2, 4 and 5, 11 and 12.).
