This represents the cost of an advance of about 8 feet. 
The cost per foot is, then, $3.64. 
Itis better, however, to figure on the cost per cubic yard ; so, 
in the above calculation, the cost per cubic yard is about $1. 
Cost of Blasting. 
The following figures in connection with the cost of drilling 
give a fairly good idea of the cost of the blasting operations:

A No. 1 powder is used in soft ground; No. 1 powder is 
used in extra hard ground; No. 2 powder is used in ordinary 
ground; gelatine powder is used in very wet ground. 
Cost of Timbering. 
As the timbering operations are almost wholly confined to 
the lining or cribbing of shafts, it is not possible to give very 
exact figures on the cost of timbering ground of varying de- 
grees of softness. The amount of soft ground is quite limited 
and the areas small and scattering. 
TIMBERING OF SHAFT 
CRIBBING. 
When round poles cut from the scrub-oak are used, the 
price per foot is from one-half to one cent, or from 5 to 10 
cents per 10-foot length. If 2-inch poles are used, consider- 
ing 22 feet of timber necessary for a 4-inch rise in a 4x5 
shaft and 28 feet of timber for a 5x7 shaft, the cost of crib- 
bing a foot of shaft in the former case is 66 cents; in the lat- 
ter, 84cents. When sawed timber is employed, the following 
figures show the cost for the various sizes employed: Two-by- 
fours, at $15 per thousand, crib a 4x5 shaft 1 foot for 99
