THE TEMPLE ON THE ACROPOLIS BURNT BYTHE PERSIANS. The excavations conducted by the Greek Archæological Society at Athens from 1883 to 1889 have laid bare the entire surface of the Acropolis, and shed an unexpected light upon the early history of Attic art. Many questions which once seemed unanswerable are now definitively answered, and, on the other hand, many new questions have been raised. When, in 1886, Kabbadias and Dörpfeld... more...

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 problem, as submitted to the writer, was to construct a yacht landing at East... more...

While engaged in such studies some years ago, the attention of the writer was attracted by the fact that the usual... more...
