106 BULLETIN" Til, U. S. DEPARTMENT OF AGRICULTURE. 
The cost at camp 1 includes the wire rope used in yarding and 
loading, including the rope used for chokers, tag lines, straps, etc. 
Straw lines were not used. One and one-eighth-inch rope was used 
for the main yarding lines; one-half -inch rope for the trip lines. 
Logs were single hauled a maximum distance of about 900 feet. The 
ground was practically leyel, quite free of pot holes and down timber, 
and contained little rocky material. The logs ayeraged about 550 
feet in yolunie, and 10 by 11 inch yarding engines were used. A gin 
pole and crotch line were used in loading, the motiye power being 
furnished by a drum on the engine. 
The cost at camp 2 includes the wire rope used for the main yard- 
ing, trip, and main loading lines. It does not include chokers and 
tag lines used in yarding, and the crotch lines used in loading, which 
cost $0,045 per thousand feet. One and one-fourth-inch rope was 
used for the main yarding lines, five-eighths-inch rope for the trip 
lines, 1^-inch rope for the loading lines. All the timber was single 
hauled an ayerage maximum distance of about 800 feet. The ground 
was practically leyel and contained no rocky material. Xot less than 
two logs were yarded at a trip, sometimes three or four, and occasion- 
ally as many as five. The yarding engines were driven at practically 
their highest speed, so that, relatively speaking, the lines had hard 
usage. The logs averaged about 600 feet in volume. The yarding 
engines were 10 by 11 inch, compound-geared. 
The cost at camp 3 includes the wire rope used in yarding and 
loading, also chokers, tag lines, crotch lines, etc. All timber was 
yarded direct to the landing at an ayerage maximum distance of 
about 800 feet. The ground was of mixed topography, being badly 
broken up as regards minor features. The logs, averaging 1,000 
feet in volume, were never moved uphill. 
The cost at camp 4 includes the wire rope used for main yarding, 
trip, and main loading lines. It does not include the cost of rope 
used for chokers, tag lines, etc., used in yarding, and crotch lines 
used in loading. The chance, from the standpoint of the ground, 
was an average one, as the country is not particularly rough or badly 
broken up. From the standpoint of brush, rotten.stumps, and down 
timber, it was much worse than the average. Part of the timber was 
double hauled, just how much is not known. The volume of the 
ayerage log was about 675 feet. 
The cost at camp 5 in 1912 includes the wire rope used for main 
yarding, trip, and main loading lines. It does not include the cost 
of chokers, tag lines, etc., used in yarding, and crotch lines used in 
loading, which cost $0,064 per thousand feet. One and one-fourth 
and If -inch rope were used for the main yarding lines; J-inch rope 
for the trip lines. The country is mountainous and badly broken 
up, the slopes being generally steep. Logs were moved both uphill
