With Discussion by Messrs. William Arthur Payne, and Eugene Klapp. A private yacht pier, built near Glen Cove, Long Island, has brought out a few points which may be of interest. It is an example of a small engineering structure, which, though of no great moment in itself, illustrates the adoption of means to an end that may be capable of very great extension.

THE DIVINITY OF OUR RELIGION AS CONCEDED BY ITS ENEMIES.
