pedal. (3) The pole must have a shape adapted to its peculiar function and its dimensions must bear the proper relation to those of the coil.

The first requirement is the most important because lack of this endangers the result of an operation. This magnet has one great advantage over all so far in use, because it permits the physician to have his hands free. The magnet is of the bell form and the working pole is a cone of 90 degrees and this end of the coil is tapered sufficiently to give the operator a clear view of the field up to the tip of the magnet pole. The idle pole is expanded into the form of a bell which covers and protects the greater part of the coil. This construction possesses the

PAINTING ORNAMENTAL PALMS, We have all heard the phrase "painting the lily" to indicate an excess of artificial beautifying, and this photograph shows an almost literal interpretation of the phrase. In this case it is the ornamental date palms on a Pacific Coast estate which are "beautified" by being trimmed with exceeding symmetry and painted white. The result is more startling than aesthetic.

HOW TO STOP A WASP PLAGUE.

Over seventeen thousand wasps were caught in an English grocery store at Hastings, by the simple process of placing a lamp with no chimney on a jam jar in the middle of water. The store was purposely made dark to attract the insects to the light which, being without a chimney, burnt off their wings and caused them to fall into the water. The weight of this lot of wasps was 54 pounds with 212 wasps to the ounce.

additional advantage of restricting the escape of lines of force to one side and diminishing the area of the external magnetic field. The apparatus is mounted on a pillar which is hollow and which contains a switch at the bottom, operated by a pedal. This switch is closed by depressing and thrown open by a spring the moment the foot is raised. A special device protects the contacts from injurious sparking.

The electromagnet is designed for use on direct current circuits of 60 to 300 volts but it can be employed on alternating, uniphase or triphase circuits with the aid of a suitable transformer.

NEXT. THE SEEDLESS TOMATO

"DOTY'S Navel Tomato" promises to

be a valuable addition to our list of vegetables, A. J. Doty an enthusiastic amateur plant breeder and horticulturist of Porterville, California, having evolved a tomato of extreme size, which is to the usual vegetable what the navel orange is to the ordinary fruit. The resemblance is borne out by the navel formation at the blossom end of the fruit, where the navel characteristics appear.

In common with the navel orange the new tomato is almost entirely seedless, the usual seed pulp being replaced by solid flesh as shown in the photograph.

Mr. Doty was at work on the tomato for several seasons before he secured the production of

ELECTRICITY FROM THE

WAVES

AWAVE motor is in operation at

Venice, California, which pumps sea water to a height of about forty feet, and which it is proposed to use at an early date for generating electricity. This will be done by pumping the water into a storage tank and allowing it to run through the turbines. The motor is built in the form of a ten-foot wooden wheel suspended on a steel shaft and this

vancing waves drive the plane toward the shore, while the receding waves pull it back again, causing the wheel to revolve back and forth on its axle and this motion is transmitted to the gear of four pumps by means of steel wire cables, and the sea water is elevated from the surface to a height of about forty feet through a three inch pipe. As this is merely to demonstrate that the force of the waves can actually deliver the water, the stream is not caught in a tank but allowed to fall back into the ocean, and the spray of falling water can be observed in the photograph of the pump just behind the figure of Mr. Lewis, the in

erected upon a revolving tower having a giant arm some 160 feet long connected to it. At the other end of this arm-not plainly visible in the illustration are two supports extending down to the ground. Thence they run upon_a circular track. By this arrangement it is possible for the loading - bridge to reach an astonishing amount of territory.

This seems to be a new principle in wave motors, and although the present model is of crude construction it actually does the work. An improved model will be built within the next few months.

shown in the illustration.

In the background of the illustration will be seen a long chute running from the top of the tower to the dock below. By means of a moving belt inside of this chute 600 tons of coal are hourly transferred through it, up to the tower, thence out along the bridge, and dumped either into piles or loaded in cars, as the case may be.

In about the center of the long arm will be seen a bucket arrangement which automatically shovels the coal and dumps it. After one pile of coal is of a certain size it automatically finds another place to dump its cargo.

It seems a bit curious-does it not?-that Americans should look abroad for an apparatus of this sort. This seems to indicate, however, that in spite of our boasted mechanical progress Europeans may surpass us in such matters after all. At any rate Milwaukee, a very enterprising city, seems to be of that

STREETS OF PARIS.

RANCH SCENES

: IN BRONZE

PRIDE in his cattle

and ranches caused Major George W. Littlefield, of Austin, Texas, to have cast upon two solid bronze doors that ornament his new bank and office building in that city panels of scenes taken from actual life upon his Yellow Horse ranch in western Texas. This ranch embraces 300,000 acres of land. The doors were designed and manufactured in New York. Each door weighs 1,300 pounds and cost $4,000. Upon the two upper panels are shown mounted cowboys, dressed in typical picturesque garb. The second panels represent cattle round-up scenes and the two lower ones show herds of the animals quietly grazing. These representative pictures were made from photographs that were taken upon the ranch.

WHOLE UMBRELLA GOES IN BAG

THERE have been

numerous umbrellas with folding or telescopic handles and sticks placed upon the market, but it has remained for a young Chicago inventor, Armand C. Pfaff, to perfect one wherein not only the stick, but the cover and ribs may be reduced to such a small compass that the entire umbrella when closed can easily be placed in an ordinary hand bag. Among the other advantages claimed for it is an improved means

231

for automatically raising the cover, when desired, with a minimum of effort.

The stick of the umbrella is formed of three sections which telescope into one another, thereby reducing its length to approximately twelve or fourteen inches when the umbrella is closed. The most novel features, however, lie in the manner of constructing the ribs supporting the cover, and the inner braces. The ribs, like the stick, telescope or slide together and when thus shortened are of an equal length to the

folded stick. The braces are pivotally connected with the ribs, and instead of moving outward toward the handle, as happens when the ordinary umbrella is closed, slide down toward the tip. Thus ribs, stick and braces are all brought together in a

parallel line, forming a compact bundle of a little more than a foot in length.

The entire structure weighs no more than an ordinary umbrella, it is comparatively simple and inexpensive to manufacture, embodies few parts and these so arranged that the danger of derangement is reduced to a minimum.

Thus, one may take the umbrella about with him, put the little hand bag under chair or other seat, and be always certain that no unscrupulous individual is making off with the precious rain protector, from hall or cloak

room.

It insures one's mental comfort at all times.
