Greatest Firm in the World

A DETROIT CAPITALIST was hur**■ rying down Griswold street, evidently in a brown study.

"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

T-HE CONNECTION that exists be*■ tween 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 i860; 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.


The Flemish Name for automobiles is said to be "Paardelooszoondeerspoormegpetroolrytuig," and there are many people in America who believe that they deserve every single syllable of it, too.

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 citizens.

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.

LITERATURE— (Continued)

pecially of the agricultural and allied industries of the great West, is none too well understood even by those who pride themselves on keeping in intelligent touch with what concerns public issues of vital interest. In opening eyes to the dangers of wholesale deforestation and reckless waste of natural resources—follies of which our own country and others furnish many striking examples—and in stimulating a sentiment in favor of rational conservation of some of the richest of our national assets, this book will render a public service of inestimable value.

The volume, though designed especially for students and others beginning the subject of Forestry, is also intended for the general reader who wishes to secure a broad idea of Forestry in North America. It covers the field in its entirety and with an abundance of detail too minute for mention here. Besides treating fully of the conditions of forest growth and management, it contains much information of practical value to the agriculturist, the engineer, the lumberman, and the woodworker. Illustrations are abundant, including many beautiful half-tones; and a complete analytical index renders all details easily available.

Elementary Woodworking. By Edwin W. Foster, Instructor in Shopwork and Drawing in the Manual Training High School, Brooklyn, N. Y. Cloth. 12mo. Pages 133. Illustrated. Published by Ginn & Company, Boston, Mass. Price, postage prepaid, 80 cents.

An Admirable Handbook of great practical value. In the hands of students it will reinforce the work of their instructors, and, while specially adapted to higher grammar grades and the lower years of the high school, it will be found replete with scientific information and practical hints of value to all woodworkers. In Part I the tools most used in elementary benchwork are described and pictured, with directions for their use. Part II deals with wood. Beginning with a description of lumbering operations, it goes on to explain such natural peculiarities as shrinkage, warping, etc. Then follows a detailed study of the woods and trees of the United States.
