Building a Chimney MANY of us who have seen factory
n 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
Saves from Flames CONTRARY to the mode of operation
of other inventions of its kind, a fire-escape that is to be used, not by the imperiled person himself, but by his rescuers, is here shown. The invention is in the nature of a substantial, portable ladder not partaking of the flimsy character of those devices which one is supposed to carry about with him in his trunk or suit-case.
The apparatus is known as the "telescope" fire-escape, from the way it is opened and closed. It is drawn about on a truck, and requires a somewhat elaborate system of machinery for its. operation. The illustrations show the fire-escape closed; also as it is when it has been released and extended up the side of a building. 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.
TELESCOPE FIRE-ESCAPE EXTENDED.
New Use for the Auto A NEW departure in the development n 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 work have a speed of 50 feet per minute and a pulling strength of 5,000 pounds, while in aërial work this is increased to 150 feet per minute with a pulling strength of 5,000 pounds.
The winches are operated by the same motive power that drives the car. A separate clutch is provided, which makes it possible to connect or disconnect the

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
