The sledge for driving the bar should not be too heavy. A man will strike more blows with a light one, which is what counts in soil. An apparatus to pull a bar when it gets tight in the ground will save con- siderable hard work and time. Power outfits for making holes for charges similar to those described on page 54 are of advantage on big jobs where there are no stones in the ground. Anyone interested should write us. The powder should be dropped to the bottoms of the holes rather than low- ered by the fuse. When charges are small pieces of sticks the best of tying of the fuse is none too secure. Caps may be pulled out of the powder very easily. Tamping should be done thoroughly, as on it depends to some extent the dis-. It is easy to see which tree is growing in a blasted bed and which is not. Both the same age and variety. A special subsoil bar usually is about 4 feet long, though any crow-bar can be used. Other tools that are needed are a wood tamping rod and the usual basket or box containing small blast- ing equipment, as described on page 9. No waterproofing material is required, since the soil must be dry when the work is done. Don't forget the gloves for handling powder. tance the blast will break the ground sideways. Dirt should be solidly tamped to the top of the hole. If tamping is neglected the blast will tend to blow out a crater. Compare, for illustration, the method of blasting post-holes, described on page 76, in which no tamping is used. The fuse (or wires) should be held to one side, or the rod may damage it.
