BANISHING THE WHEEL

BARROW AN

N invention which seems to do away

with the wheelbarrow, at least as far as the laying of brick pavement is concerned, is shown in the illustration. The device, which is known as a roller brick carrier, looks like a long steel ladder laid in an inclined position from the sidewalk to a point near the center of the street. What appears to be the rungs of the ladder are really steel rollers set very closely together and running on ball bearings, upon which the bricks are laid and allowed to run down to the street by gravity. To keep the bricks from running off the sides, the rollers are made with flanges at the ends. Among other advantageous features, the carrier delivers the bricks to the exact point where they are to be used, saving the two handlings which are required when the material is delivered with the wheelbarrow. Such an invention as this makes for speed, profit, and efficiency.

A KEYLESS LOCK

the market, resembles in appearance almost any other door lock in a general way, having a handsome door plate and knob, but at the right side and a little below the knob is a series of four small levers. These operate in various combinations known only to those who are permitted free access to the house, and can be changed to a different combination when necessity demands. The lock can be adjusted so that it will lock on closing or by turning the small button underneath the knob. It is opened by pulling upward one or more times on one or more of the levers at the side. So simple is its operation that a child too small to unlock a door by means of a key can readily gain admittance with the keyless lock. This keyless mechanism can be attached to any standard lock so that the purchase of an entire new lock is not

a long distance, by day or by night, on the dials, and every quarter-hour between sunrise and sunset the chimes peal out in strong, harmonious tones. From sunset to sunrise powerful flashes of red and white light, streaming from the tower tip and visible on clear nights for fifteen miles, announce the hour.

SCULPTURED GLASS A WONDERFUL example of the

glassmakers' art is that depicted in the accompanying photograph. It is a piece of sculptured glass in the form of à beautiful plaque. It has the appearance, too, of a delightful cameo. This effect is produced by fusing a thin layer of opaque white glass on a thick layer of dark brown glass. The design is carved upon the white surface, and the various depths of the carving allow the dark background to tint the white glass to different shades, exactly as in a real cameo. Naturally, the work has to be done by a skilled artist by hand and it occupies a great deal of time. The plaque shown took eighteen months from start to finish and is valued at several hundred dollars.

A HUGE CLOCK HALF-WAY up, the 700-foot white

tower of the Metropolitan Building, New York City, at the 26th story, are the four dials of the most remarkable timepiece in the world. The dials are 26 feet 6 inches in diameter, with Arabic numerals 4 feet high and 60 circular minute-marks each 10 inches in diameter. The clock and its no less remarkable auxiliaries, the chimes at the 46th story and the flashing lantern at the tip-top of the tower, constitute a stupendous advertisement. The time can be read from

AN ISLAND THAT Floats. Extraordinary formation of lands on water's surface

ai Lake Sadawga, Vermont.

FLOATING ISLAND
IN Whitingham, Vermont, on a small

body of water known as Lake Sadawga, one can see the unusual phenomenon of seventy-five acres of unattached soil locally famed as "The Floating Island.” This island consists of a vast nexus of roots of reeds and trees which are overspread by a thin layer of earth. Quantities of moss, flags, cat-tails and other vegetation which favors moist localities, are found in great profusion. The trees are mostly beeches and firs, some of which are of great age, but they grow to a height of only about twentyfive feet, and at that point the growth is arrested, probably on account of interference with their nutrition. Fishermen cut holes through the soil and fish through them just as one fishes through the ice in winter.
