Table III. — Field record form used in maldng individual-tree records in the orchard. 
[This blank provides space for recording data from four 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 R'.]

1 Each tree in the investigational plat was given an individual-tree number which included the block 
number, row number, and location of the tree in 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 OF DATA. 
In the succeeding tables only the computed figures for the different 
platg; 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 m 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 ia Tabls II, the first
