A TRIUMPH IN BLASTING.

By the blasting of a huge bowlder twenty feet below the surface of the northwest corner of Central Park, New York, two shafts through solid rock, begun one thousand seven hundred and twenty-five feet apart, were joined. The work was carried out with such exactness that the junction was as clean cut as if the mining had been along one continuous stretch. The engineers have had to exercise much care, and the blasting has proceeded with the greatest caution, one of the principal fears being that they would come upon a change in the texture of the rock. This is not always to be foreseen and may cause fatal accidents.—Christian Advocate.
