COMPOSITION OF CALIFORNIA LEMONS. 5 
though not too small to preclude satisfactory results had the varia- 
bility encountered been less. While the averages of the three sets 
are taken from a sufficient number of samples to make them worthy 
of consideration, the monthly averages depend on but three samples, 
too small a number from which to draw conclusions. Moreover, 
neither Tulare County nor Arizona is a large lemon-shipping center, 
and the number of samples analyzed from each of these districts was 
small. In Tulare County the lemon season begins in September and 
lasts but a few months, so that comparison with lemons grown in 
other districts throughout the season is impossible. The data con- 
tained in Tables 3, 4, and 5, however, are of no little interest to lemon 
growers, and it is felt that they should be published here.
