Although during these four years Section B 

 received 80 acre inches of irrigation water as against 

 58 acre inches received by Section A, yet the growth 

 and general health of the trees on both sections, 

 which are situated on similar soil, was, as far as all 

 appearances went, identical. However, during the 

 1917-18 season, as shown by the occasional wilting 

 of some of the trees, it was evident that Section A, 

 with 13 inches of irrigation water, had received the 

 minimum amount, lower than which it was not safe 

 to go if the crop was not to be lost. Nevertheless, 

 on Section C, during the 1917-18 season, the appli- 

 cation of 14 inches of irrigation water proved suffi- 

 cient to mature an average crop of four cases of 

 fruit per tree from a section of mandarins situated 

 on land of a similar nature to Sections A and B. 



The argument is sometimes advanced by fruit- 

 growers that although it is possible for young trees 

 and vines to make satisfactory growth on small
