plementary to larger engines. The maximum yarding distance is 
usually from 1,000 to 1,300 feet. The larger timber, where logging 
conditions are good, is mostly yarded by slightly larger machines, 
such as 10 by 12 inch and 10 by 13 inch tandem drum yarders, and 
10-J by 10| inch and 10 by 11 inch compounds. The maximum yard- 
ing distance usually ranges from 1,300 to 1,600 feet. 
The machines commonly used for logging in the harder chances in 
the Sierras, where long hauls and uphill pulls are necessary, are still 
larger. The smallest are 11 by 13 inch yarders and the largest 12 
by 14 inch. The latter are the largest on the market. The maximum 
yarding distance is usually 2,000 feet, sometimes 2,200 feet. The 
tendency is to replace worn-out yarders by larger machines, and the 
manufacturers have accordingly been turning out larger engines each 
year. 
Table 3 gives the approximate prices, f. o. b. factory, for yarding 
engines.

The approximate cost of most yarding engines can be arrived at 
by allowing 10 cents for each pound of weight. 
Freight to California points is about $200 on small engines, $250 
on medium, and from $300 to $350 on large engines. In addition 
each yarder must be equipped with a sled. These range in length 
from 20 feet for small yarders to 40 feet for large machines. They 
are usually built by the logger and cost from $200 to $300 each. 
Either wooden or steel water tanks are built for each machine and 
placed on the rear of the sleds. The steel tanks give the best service 
and cost from $100 to $200 each, depending upon the size of the 
machine. Usually a shelter with a corrugated iron roof is placed
