While the yields are not high, they are considered very satisfac- 
tory, coming from land which had previously been unproductive. 
They indicate that, so far as the surface soil is concerned, the land 
has been fairly well reclaimed. 
Cost of the method. — A record has been kept of the work done on 
this land from the first plowing in 1910 to the end of the season of 
1912. In order to get an idea of the cost of the treatment, the 
different operations applied to the land have been listed and the cost 
of each has been estimated. The figures are given in Table V.

SECOND METHOD. 
The practice of alternate irrigation and cultivation was not started 
until September, 1911. The season was then so far advanced that 
it was not possible to accomplish much during the remainder of that
