COST OF PRODUCING APPLES IN YAKIMA VALLEY. 23 
DISPOSAL OF BRUSH. 
Several rather widely varying methods of brush disposal are em- 
ployed, hence there is considerable range in the cost of this operation. 
A normal time could not be expected where there is such a wide varia- 
tion in controlling factors. The regularity of pruning, the amount 
and kind of wood removed, as well as the method of handling and 
disposing of the brush, each has a considerable bearing on the time 
required for this operation. The cost of disposing of brush is nearly 
proportionate to the cost of pruning.

There is little difference in the cost in the orchards under clean- 
cultural as compared with those under mulch-crop management. 
Considering all the records taken the former cost per acre is $4.59 
and the latter $4.53. (See Table XV.) 
The two more common methods used in disposing of the brush are: 
1. A crew of either one man and one horse or two men and team 
with a wagon or sled is used to pick up, haul, and burn the brush left 
by the pruner. 
2. The brush is often placed in piles. A crew, varying in size as 
stated above, pick up the brush either by hand or with forks, haul, 
and burn it. 
In some instances a horse rake is used to clean up and carry the 
brush to a burning-place. However, two-man and two-horse crews 
are most commonly used in brush disposal in both the upper and the 
lower valley. 
It is a general practice in some orchards where large limbs are 
removed to have the same trimmed up and used for fire wood. Where 
such a practice is usual, the time required for trimming up, together 
with the hauling of the wood to the ranch house, is considered and a 
credit to the orchard is made for the same. 
There is little difference between the cost of removing brush in the 
North Yakima and in the Zillah districts. Considering all records
