A New Foundation Method.

The Literary Digest quotes from a foreign engineering paper the description of a new method of making foundations now used in all sorts of conditions. It is known as the compressoi system. It consists in making holes through the soft soil down to thj hardpan by means of a tapering arm, which is forced down like a pile driver, and then filling these holes with stones and rubble in successive layers, each.of which is firmly rammed down. The result is to produce a monolithic block of great strength. No ground is removed in the boring of the shaft, the sides of which acquire great compactness. =—- •. . .. '■ ~
