The article on Amateur Engineering, by E. P. Watson, proves the expediency of placing an undertaking in the hands of a trained engineer rather than attempting to do the work oneself without the proper knowledge.

and New York TIIE FIRST ARTICLE is on “Concrete-Steel Bridges at Dayton, Ohio.” The concrete construction is becoming such an important factor in the building trades at the present time, that these articles are always read with great interest.
Another interesting article is on “Paving Materials,” by John W. Alvord, C. E. In this article the writer gives an excellent description of the most common kinds of pavement, such as asphalt, stone pavement, brick, wood, macadam, and bitulithic.
The usual interesting departments, Question Department, Notes on Water Supply, Cement and Concrete, Streets and Lighting, Sewerage, etc.—are excellent.

the New Science Library, but they would have considered it an extraordinary work of fiction, with its story of electric currents flashing messages through space half around the world ; of a metal so rare that it costs half a million dollars an ounce; of astronomers determining the exact constituents of a star a trillion miles away; of a theory of evolution which carries the origin of man back millions of years to a lower form of life.
They would have found a surprise on every page-yet the New Science Library is filled with sober facts, which the amazing progress of the last fifty years has brought to light. Until you read this magnificent record of man's achievements you cannot realize fully how science has transformed the entire fabric of intellectual and commercial life. It describes simply, clearly and accurately the great inventions and discoveries of the nineteenth century. It will tell you what the famous Darwinian theory is; how the sun and planets are weighed and their motions charted; how liquid air is made and used; what radium is; what ideas Herbert Spencer brought into the world—and a thousand other interesting things you have always wanted to know. It teems with ideas and suggestions, as well as with facts. It will lift the reader out of the dull circle of commonplace things.
The New Science Library is the autobiography of the nineteenth century-written by the men who made modern science. It consists of sixteen volumes covering comprehensively the whole field of Evolu on, Astronomy, Invention, Geology, Electricity, Political Economy, and Anthropology. This Library is a necessary set of books-necessary to the reader who expects to be well informed. Among its authors are Spencer, Darwin, Proctor, Lubbock, Huxley, Tyndall, and other leaders of modern thought. It is a work to be read and enjoyed, for the great authors who wrote it were too close to nature to be dull and too big and human to be narrow.

U. S. A. Bulletin No.8. Pages 16. Paper, 8 by 10
inches. THIS BULLETIN describes the general features and advantages of the Jeffrey Gathering Locomotives. The several illustrations show some of the types of Gathering Locomotives. They are made in different sizes, and are equipped with either one or two motors, dependent upon the weight of the locomotive. The distinctive feature of the electric gathering locomotive is that it may be operated over tracks where there is neither trolley wire nor steel rails. This is made possible by carrying upon the locomotive a reel of flexible, insulated conductor, which is operated by a friction-clutch positively driven by a silent running chain and sprocket from the motor, the control of the clutch being placed within easy reach of the motorman at the operating end of the locomotive.
The use of Jeffrey Gathering Locomotives has many advantages. It reduces the wear and tear of the road-bed; the gathering of coal is performed with regularity, causing little or no confusion; and the air in the mine, on account of absence of mules and horses, can be kept pure.
