1 Every operator finds it necessary to carry certain repair parts and materials in stock. 
While the value of these parts varies, it is thought that the amount given in the table is 
ample in most cases. One operator, employing 5 yarders, carried parts and materials in 
stock to the amount of $1,700. This stock was made up of an extra guide and crank pin, 
brasses, valve stems, a steam gauge, gauge glasses, an extra cylinder head, a supply of 
valves for vulnerable parts of the engine, a small but complete set of pipe fittings and 
valves for water system, packing, etc.
