MARINE REVIEW. 15 exhibits from such firms as William Denny & Bros., J. & G. Thompson, Laird Bros., Armstrong, Mitchell & Co., the Fair- field Ship Building and Engineering Company and many others, there are models of the greatest merchant and naval vessels in the world, some of which will receive special attention in. future issues. One picture in William Denny & Bros. collection, that of the experimental tank, has been given special attention by naval men visiting the fair, and we have received, in addition to an engraving of the picture, a very complete description of this tank from the Dumbarton firm, which will be published in the next issue of the REVIEW. It is well known that the yard of Messrs. Denny is one of the most widely known and scientifi- Mr. Geo. G.

The exhibit of this company is among the most interesting in the exposition. Sections of cables, specimens of fractured cables, a complete working outfit of instruments, and in fact all of the detail necessary to represent cable sending and receiving stations are to be seen in this pavilion, and the repre- sentatives of the company are attentive in giving out information. Less than fifty years have elapsed since the first Atlantle cable was projected, yet there are 143,000 miles of cables in successful operation throughout the world. Eleven cables connect America cally conducted yards on the Clyde, and a description from them of the famous experimental tank will undoubtedly prove interesting. SUB-MARINE CABLE DISPLAY. A picture of the famous Great Eastern in a Storm, which appears in connection with this description of some of the features of the fair, is taken from a large engraving of the original, which has a prominent place in the interesting exhibit of the Commercial Cable Company, occupying a pavilion in the gallery of the electricity building.

A cable may be laid from San Francisco to China, but at present all messages to that far-away country cross under the Atlantic, the Mediterranean, the Red and the Arabian seas to Bombay, thence by land to Madras, and beneath the waves of Singa- pore, a distance of nearly 15,000 miles under the sea and 10,000 miles on land, A message from Chicago would follow this route and cost $2.02 a word, while the charge for messages to England, France or Germany is but 31 cents a word. The length of time required in cabling varies slightly according to the conditions, but a question has been sent from New York to London and instantly answered by the operator, all within the
