. 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.
