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.
