Case 1. — The cost includes the clearing of site, yarding of the material, excavating for brow skids, etc., 
preparing and raising gin poles, swinging loading rigging on poles, digging settings for yarding and loading 
engines, as well as building the landing proper. The common labor in this case, as well as in the other two, 
did the pick-and-shovel work and such swamping as could be done by hand. 
Case 2. — The cost includes the same items of expense as the previous case, except that it does not include 
the cost of preparing and raising the gin pole and the swinging of the loading rigging. 
Case 3. — "With the exception of the water system, this case includes the same items of expense as Case 2. 
Generally speaking, the same equipment is nsecl in building land- 
ings as in yarding, viz., a steam yarding engine, lines, blocks, 
chokers, etc. 
One company has used a gasoline logging engine successfully for 
two years in building landings. It resembles the steam logging en- 
gine in a general way, and is a 40-horsepower two-cylinder, opposed 
type of engine. The combination of gears, drum, and frictions 
yields a high tractive efficiency, and gives, it is claimed, an engine 
that is capable of withstanding hard service. The drums and gears 
are erected on a built-up steel frame. The engine and 200-gallon 
water tank are independent of the drum mechanism, and are bolted 
securely to the sled. The power is transmitted by a No. 78 Grriplock 
steel chain drive about 8 feet long, running from a 12-inch sprocket 
on the engine to an 18-inch sprocket on the countershaft, the latter 
being fitted with a 9-inch pinion. The engine has three drums, the 
frictions being such as to require very little pressure to hold the 
heaviest strain. It weighs about 7 tons, and is mounted on a sled 
32 feet long and 4J feet wide. A compressed-air tank, charged from 
the cylinders, furnishes about 50 pounds pressure for the operation 
of the signal whistle. The main drum carries 1,500 feet of f-inch 
line ; the trip drum, 3,000 feet of 4-inch line ; the loading drum, 300 
feet of f-inch line. The main yarding line can be made to travel 
500 feet per minute ; the trip line, 800 feet per minute. The cost of 
. fuel has been approximated at $2.70 per 10-hour clay, consisting of
