MINE EQUIPMENT. 

 In conjunction with the operation of coal mining, there is usually main- 

 tained a wood-working department for the manufacture and repair of all 

 wooden equipment required in connection with the work. Table 55 includes 

 all the kinds of material used for these various purposes except that used in 

 the rough, as props, lagging, caps, segments, sills, etc. In the interior of 

 the mines lumber goes for uses in connection with ventilation schemes; brat- 

 tices, doors, airways, manways, and for pit railing, etc. On the breakers 

 in collieries it is used for tipple parts, drum bands, chutes, screens, scraper 

 lines, flights, etc., besides it answers for parts of haulage systems, slope 

 rollers for example, and for sprags and various other less important com- 

 modities. The lumber used for mine cars and their repair has been included 

 as shown above, under car construction, while that going into manufactured 

 parts for houses, buildings, and other building operations was listed with 

 similar material under the planing mill industry. The available statistics 

 reported by both anthracite and bituminous operations in Pennsylvania are 

 as follows:
