THE BEHAVIOR OF HEATED AND NONHEATED PLATS IN 1914. 
Although practically all the nonheated plats had returned to nor- 
mal production by January, 1914, in order to collect data on the 
behavior of trees in the year following the freeze it was decided to 
continue the individual-tree records in plat 6, a heated acre of Lisbon 
lemon trees, and in plat 8, which had not been protected in 1913. 
The production by grades in these plats during the calendar year 
1914 is shown in Tables XX and XXL 
Table XXI. — Total estimated production by grades from plat 8, an acre of Lisbon 
lemon trees, for each picking during the calendar year 1914. 
[The data in this plat were computed from tbe individual-tree records often Lisbon lemon trees. This plat 
was not heated during the winter of 1913 and was selected for comparison with plat 6 in an orchard of 
Lisbon lemon trees which, was heated during that period. The data from plat 6 for the calendar year 1914 
are shown in Table XX.]
