"Hey, there!" yelled an acquaintance, slapping the future millionaire on the back just to be able to say in after years that he had once done so. "What are you thinking about?"

"The greatest firm in the world, which does more business, loses more money, and fails oftener than any other, and yet never dissolves partnership," was the sudden and puzzling retort.

"Name it," said the questioner.

"Didn't Know, Didn't Think, Forgot & Co.," was the laconic reply.

Port Arthur's Name

THE CONNECTION that exists between Port Arthur and a peaceful village in Devonshire is little known. Half a century ago the rector at Atherington was the Rev. James Arthur, father of Lieut. W. Arthur, R.N. Lieutenant Arthur, about 1859, was sent in command of the gunboat Algerine into Chinese waters. The Algerine was attached to a surveying expedition prior to the landing made by the English and French in 1860; and when the flagship Acteon was disabled, Lieut. Arthur towed her into the then unnamed harbor, which was thenceforth known as Port Arthur. Lieut. Arthur afterwards attained the rank of rear-admiral.

BOOKS RECEIVED

Irrigation Engineering. By Herbert M. Wilson, C. E., Author of Topographic Surveying," etc. Fourth Edition, Enlarged and Rewritten. Cloth. 8vo. Illustrated with 141 full-page plates and 142 figures. John Wiley & Sons, Publishers, New York, N. Y. Price, $4.00.

IN VIEW of the vast work of reclamation which is to be undertaken by authority of Congress in the arid and semi-arid regions of the West, in connection with which hundreds of engineers, young and old, have already found employment, the appearance of a work like this, embodying an up-to-date exposition of the underlying principles of irrigation engineering, is an event of importance not only to the profession but to all intelligent citi

zens.

Irrigation is a subject little understood by the generality of readers. Here it is treated in exhaustive detail and with abundant illustration. The agricultural significance of irrigation is set forth, and the various methods of gathering, storing, and distributing water are described, with specific accounts of the most important irrigation works in all parts of the world. Not only will the practical engineer find an abundance of useful suggestions based on the experience of others, but the general reader also will find in this volume a wealth of information of absorbing interest.

Principles of American Forestry. By Samuel B. Green, Professor of Horticulture and Forestry, University of Minnesota; Member of the Forest Reserve Board of the State of Minnesota; Author of "Forestry in Minnesota." Illustrated. Cloth. 12mo. Pages 347. John Wiley & Sons, Publishers, New York, N. Y. Price, $1.50.

THE REVIVAL OF INTEREST in the general subject of Forestry makes this a very timely volume. The importance of the subject, its intimate relation to the welfare of the country in general, and esMention The Technical World.
