(c) Maintenance of locomotives and trucks (labor) : This segre- 
gation includes the labor cost of repairing the three locomotives 
already described and 33 sets of trucks. The upkeep of the engine 
used on the spurs was very high because the engine was not built for 
the service demanded of it. It was of an early type, having a very 
light driving shaft, which caused a number of breakdowns during 
the year. 
The regular machine and blacksmith force consisted of the follow- 
ing: 
Per day. 
Blacksmith 85. 00 
Blacksmith's helper : 3. 25 
Mechanic 5. 00 
Car tinkerer 3. 25 
During a part of the year, a mechanic assistant and a carpenter 
were employed; then, too, when a locomotive was in the shop, the 
train crew assisted with the repairs. It should be stated that the 
blacksmith and his assistant spent a large part of their time in re- 
pairing logging equipment, such time being charged against the 
cost of upkeep of such equipment. 
(d) Depreciation on track supplies: This segregation includes the 
depreciation on ties, steel rails, bolts, nuts, spikes, rail braces, tie 
plates, angle bars, etc.

the average output per day amounting to about 150.000 feet. 
A portion of the salaries of the foreman and bookkeeper, and all 
the salary of the civil engineer are prorated against the labor cost. 
Two geared locomotives, one 33 and one 42 ton, were used to haul 
the logs and do miscellaenous work about the camp, including rail- 
road construction. The haul from the landings to the dump and 
the camp (buildings) had practically a water grade, the 42-ton
