PLOUGHING BY DYNAMITE
Ploughing by dynamite is being carried ou, extensively in the United States. The famous Dupont Company —one of Schwab's enterprises, which last year showed a -profit' of twenty millions sterling—who are the biggest manufacturers' of explosives in the world, have invented a system which enables the farmer to till virgin land by -means of specially prepared lowpower dynamite cartridges, which are i placed at intervals of ten yards. The dynamite makes a regular furrow, similar to that made by a plough, aiid the depth can be graded as required. The explosion is so delicate that farm hands who-are drilling the hole for the second cartridge are not injured By the explosion of the first ten yards back.. Stumps of trees are readily removed, and during peace time the scheme is recommended for the construction of .buiiKers and undulating greens on golf courses. Low-grade cartridges are also now used for breaking up boiTers, whether embedded in brickwork or not, which have hitherto had to bo broken up by hand with great trouble and expense.
