IRRIGATION. 
In the Los Angeles and Salinas areas irrigation is frequently 
necessary in the production of sugar beets. Usually one irrigation 
is required. 
Different methods are employed in applying the water. In the 
Los Angeles area the water is pumped from wells and forced through 
portable galvanized iron pipes (see figs. 12 and 13). These pipes, 
10 to 12 feet long, with a diameter of 8 to 10 inches, are fitted to- 
gether and stretched across the beet field. The entire ROU | is covered 
by moving them from one place to another, the land adjacent to the 
pumping plant being watered last. In a number of cases under- 
ground,concrete pipes are used to carry the water from the well 
out into the field, where a number of outlets are provided for at- 
taching the galvanized surface pipe. This method requires less sur- 
face pipe than the first, and less work in moving pipes from one 
place to another. It is a comparatively expensive method, however, 
requiring a large investment in equipment. 
This system of irrigation is known as the flood system and the 
water is applied to the growing crop usually during the latter part 
of July or the first part of August. 
In the Salinas area winter irrigation is usually practiced. In most 
instances the water, as well as the labor for applying it to the land, is 
furnished by the sugar company at a flat rate of $3.75 an acre. The 
water used is the factory waste water, and it is applied in October 
put in other men to complete any work unfinished or neglected by the party of the 
second part and charge the cost of such labor to the party of the second part. 
In consideration whereof the party of the first part agrees to pay to the party of the 
second part for thinning, hoeing, weeding, topping, and loading beets, as follows:

Fractions of tons per acre in proportion. 
The tonnage per acre to be determined for each field upon the net weight of the beets 
received by the sugar factory. 
During the course of the work the first party agrees to pay the second party a sum 
not exceeding 80 per cent of the amount covering work already done, the balance to be 
paid when the work specified in this contract shall have been completed to the satisfac- 
tion of the first party. 
The sum not to exceed 80 per cent of the amount covering the work already done is 
to be based on $ per acre for thinning, $ per acre for the first hoeing, and 
$ per acre for the second hoeing, and the balance for topping and loading, ac- 
cording to schedule of prices stated in ‘this contract.
