STEAM ENGINE VALVES. By THOMAS HAWLEY. In considering the slide valve in its simple form with or without lap, we find there are certain limitations to its use as a valve that would give the best results. The limitation of most importance is that its construction will not allow of the proper cut off to obtain all the benefits of expansion without hindering the perfect action of the valve in other... more...

Bulletin No. 6 of Missouri Agricultural College Farm is devoted to an account of experiments intended to demonstrate the relation of dew to soil moisture. Prof. Sanborn has prosecuted his work with that patience and faithfulness characteristic of him, and the result is of a most interesting and useful nature. The Professor begins by saying that many works on physics, directly or by implication, assert... more...

PROGRESS OF ANTWERP. Antwerp is now the chief port on the Continent. Since 1873 the progress has continued, and made very rapid advances. In 1883 the tonnage of the port reached 3,734,428 registered tons. This marvelous development is partly due to the position of Antwerp as the embarking point from the Continent of Europe to America, and partly also to the recent additions and changes which have been... more...

THE RIGHI RAILROAD. In the year 1864, the well-known geographer, Heinrich Keller, from Zurich, on ascending to the summit of the Righi Mountain, in the heart of Switzerland, discovered one of the finest panoramic displays of mountain scenery that he had ever witnessed.

The City of Victoria is situated on the southern end of Vancouver Island, in the Province of British Columbia, Canada, and is the capital of the Province.

IMPROVED DYNAMO MACHINE. The continuous current and the alternating current generators invented by Dr. J. Hopkinson and Dr. Alexander Muirhead are peculiarly interesting as being probably the first in which the bobbins of the armature were wound with copper ribbon and arranged on a disk armature much in the same way as was afterward done by Sir William Thomson and by Mr. Ferranti. In the... more...

EMPEROR WILLIAM II. OF GERMANY. Since William II. of Germany ascended the throne as German Emperor and King of Prussia, on June 15, 1888, the eyes of Europe have been fixed on him. He has always been rather an unknown quantity, and he is regarded by the powers as an enfant terrible. The press of the world delights in showing up his weak points, and the "war lord" undoubtedly has them, but, at... more...

THE RAPHAEL CELEBRATION AT ROME. The most famous of Italian painters, Raffaele Sanzio, whom the world commonly calls Raphael, was born at Urbino, in Umbria, part of the Papal States, four hundred years ago. The anniversary was celebrated, on March 28, 1883, both in that town and in Rome, where he lived and worked, and where he died in 1520, with processions, orations, poetical recitations, performances... more...

Editor Prairie Farmer—I write you in regard to the corn question. I would like to know if angle-worms damage corn. Eight years ago I came to the conclusion that I could raise double the number of bushels of corn that I was then raising. I then commenced experimenting on a small scale. I succeeded very well for the first three or four years. I got so that I could raise over ninety bushels per acre. In... more...

METAMORPHOSIS OF THE DEER'S ANTLERS. Every year in March the deer loses its antlers, and fresh ones immediately begin to grow, which exceed in size those that have just been lost. Few persons probably have been able to watch and observe the habits of the animal after it has lost its antlers. It will, therefore, be of interest to examine the accompanying drawings, by Mr. L. Beckmann, one of them... more...
