16 BULLETIN 815, U. S. DEPARTMENT OF AGRICULTURE. 
In Tables III and IV are presented the detailed performance 
records of 25 representative trees from the Lisbon investigational 
plat, includmg examples of all the strains. These trees were arbi- 
trarily selected by taking every fourth tree of the Lisbon strain, 
as listed in Table I, every eighth tree of the Open strain, every third 
tree of the Bull and Dense-Unproductive strains, and two of the 
three trees of the Sporting strain, always including the highest and 
lowest ranking trees of each strain. In this way the selection included 
6 trees of the Lisbon strain, 10 of the Open strain, 4 of the Bull strain, 
2 
3 of the Dense-Unproductive strain, and 2 of the Sporting strain.

Formance-record plat, showing also the strain and the rank in crop production of each 
individual tree for the 4-year period from July, 1913, to June, 1917, inclusive. 
[The positions of trees in ranks 22 and 81 are not indicated in the table. They were both No. 10in rows 25 
and 83, respectively, both belonging to the Sporting strain. The tree numbers count from the southern

The following notes regarding some of the methods of recording 
and compiling the data presented in Table III may assist the reader 
to understand and interpret it. 
Commercial performance records were not being obtamed on the 
erchard in which this piat was located, and the workmen were 
unacquainted with such operations. Consequently on a few occasions 
the fruit from some of the performance-record trees was removed 
by the regular workers in the grove before the records were made. 
Fortunately the most of such losses occurred in the summer or 
fall when the production was light and the total recorded crops 
were not greatly affected thereby, but the record for tree 1-83-10 
is considerably reduced by similar losses in January and February, 
1914, at which time the production was very heavy. At least 200 
pounds of fruit was picked at that time and not recorded, so that 
the relative rank for this tree is really considerably higher than is
