The approach consists of masonry arches. An unusual feature in the construction of this bridge was that electricity was extensively employed in the work. With great pomp, King Edward opened the bridge for traffic, he being the first passenger to cross.


Building a Chimney MANY of us who have seen factory

chimneys projecting into the air, some a hundred feet and over, may have wondered how they could be constructed so solidly, yet without being crooked. The accompanying photograph gives an idea of how they are built. When the brickwork is completed a few feet above the ground, rods of iron are fastened

Where there is no fire-escape attached to the building, or where it is necessary to fasten several ladders together, the telescope method should prove invaluable.


New Way to Waves FOR electricity, still another use has

been found-namely, in the launching of vessels. The British battleship Agamemnon, recently launched, slid to the water by this new method. A series of interlocking levers were connected with the electrical arrangement. The Countess of Aberdeen, who performed the ceremony, turned a wheel which controlled the apparatus, thus closing the circuit and releasing the triggers that held the manof-war on either hand. The time occupied by the ceremony was very brief. From the instant the Countess put her hand to the wheel, to the ship's clearing the ways, was a matter of but one minute and fifty seconds.

To safeguard against the contingency of the vessel's not starting of herself, powerful hydraulic rams were placed, one on each side of the vessel. No use was found, however, for either of these.



New Use for the Auto A NEW departure in the development

of the automobile truck has been tried by the Bell Telephone Company with great success. Every one is familiar with the enormous winch wound around with lead piping which is laboriously unwound by muscular laborers for burial in the subway. The old process of pulling overhead and underground cables is entirely done away with by the use of the auto-truck. The truck is equipped with two winches, which, for underground

The Early Bird One of the rural schools in Kansas has a pretty girl as its teacher, but she was much troubled at first because many of her pupils were late every morning. At last she made the announcement that she would kiss the first pupil to arrive at the schoolhouse the next morning. At sunrise the three largest boys of her class were sitting on the doorstep of the schoolhouse, and by 6 o'clock every boy in the schoool and four of the directors were waiting for her to arrive.—New York Tribune

A Lecture on Finance Non', money's most mysterious stuff;

You can't say where it's rated;
For if you haven't quite enough,

For sorrow you are slated;
If you've too much, again it's tough-
You get investigated.
