Table III. — Field record forvi used in vialzing individual-tree records in the orchard. 



[This blank provides space for recording data from lour trees at one picking. The fruits were sorted into 

 the following grades; Green, Tree-Ripe, Frozen, and Cull, and the number and weight of the fruits in 

 each grade are recorded. The record thus made in the orchard was afterwards transferred to a yearly 

 series form, as shown in Table IV.]

I Each tree in the investigational plat was given an individual-tree number which included the block 

 number, row number, and location of the tree m the row; thus tree 1-26-17 means that that particular tree 

 is in block 1, row 26, and the 17th tree from the end of the row, always numbering from some fixed point. 



The data secured for each tree at each monthly picking were trans- 

 ferred to a yearly series record form, as shown in Table IV. The num- 

 ber and weights of the Green, Tree-Ripe, and Frozen fruits for all the 

 record trees in each plat were added at each picking and multiplied 

 by 10 or 20, as determined by the number of record trees, to secure 

 an approximate record of the plat on an acre basis.

PRESENTATION OP DATA. 



In the succeeding tables only the computed figures for the different 

 plats, as shown on an acre basis, are given. It is thought that the 

 presentation of the average number of sound and frozen fruits for each 

 month in the year in all the plats, as expressed in acre terms, will give 

 the reader a comprehensive idea of the behavior of the different or- 

 chards under observation. As will be noted in Tablo II, the first
