BIG QUARRY BLAST
CLIFF FACE SHATTERED SEVEN TONS OF EXPLOSIVES One of the largest quarry blasts seen in the Dominion was carried out on Saturday when between 120,000 and 150,000 tons of rock were shattered by the firing of 7i tons of explosive in Mr. W. A. Smeed’s quarry on the Waikato River between Tuakau and Mercer. For some weeks preparations for the blast had been in progress. Tunnels and crosscuts had been cut into the cliff and the passages filled with 280 cases of three kinds of explosives, buried in the rock. A cliff of basalt nearly 100 feet high was reduced to an enormous heap of broken boulders at one-eighth of the cost of producing metal by hewing and hauling.
