Right through his shoes and stockings the X-Ray penetrated and the clasps on the card cases stood out good and clear to the eye of the examiner. The buttons on several pairs of gloves betrayed their presence next to the skin, somewhere in the region of the heart, of a French official who tried to fool the little machine by wrapping each glove up first in linen then in tissue paper. The X-Ray saw through his deception immediately. He was accused of "carrying concealed buttons which were perhaps attached to some dutiable articles." He confessed like a man and the X-Ray received another good mark as a detective.

New Air-Ship Model AUGUST KINDLER, of San Fran
cisco, has constructed the model of a flying machine that is designed to operate somewhat on the same principle as
cinating but elusive problem of aërial navigation. His model, as has been stated, works admirably, and gives a
basis for the inventor's high hopes.
Bones of the Dead ON a little island in the Columbia
river is one of the most notable Indian burial grounds in America. In fact, Memaloose island was considered a sacred spot by the tribes who in the past inhabited the valley of the Columbia. Although situated at a point where the

This island covers but a few acres. It is located not far from the formation known as the Dalles, where the river rushes through a crevice in the cliffs which line the shore on either side. There is a legend that at one time a great natural bridge spanned the Columbia at The Dalles, but that one of the Indian gods in a fit of anger wrenched it apart and destroyed it. The legend states that Memaloose island was a part of this bridge which was hurled in the river, and this is why it was considered sacred by the natives.
Tapping an Oil Well THE 'HE extent of the oil deposits of Cali
fornia is so great that while the bulk of the various forms of petroleum is pumped from wells driven at various distances into the earth, some of the deposits are so near the surface that the removal of a few shovelfuls of sand or earth reveals the oil “springs," as they are called locally. When an oil spring is "tapped, it is often drawn off like so much water by means of troughs or wooden conduits, open at the top, and accumulated in the reservoir by gravity. The accompanying photograph shows an oil spring in the
desert foothills and a type of the conduit. The thickness of the petroleum is well illustrated by the picture.
THE loom, whose busy
shuttle is proverbial, is to become silent. A mechanism has been invented which propels the shuttle noiselessly across the shed, obviating the picking motion that makes the whirring sound. The new device works much on the same principle as does an orange seed shot out from between thumb and finger by pressure. In the new invention the shuttle is mounted on wheels. Small fingers protrude about the shuttle race. The fingers give a sinuous motion.
As each wave of motion passes, the shuttle is pressed forward by it. For weaving goods of high grade, the mechanism is particularly valuable.
Automobile on Fire WE
E frequently hear about automobiles
taking fire and being consumed, but seldom is a camera available so that a picture can be taken showing just how they burn. In this instance, however, a photographer happened to be on hand just as the touring car ignited, and made several pictures showing the fire in various stages. The destruction which gasoline will cause is well shown in the view taken after the car began to blaze. The accident occurred in Cleveland, Ohio, the gasoline taking fire from some unknown cause. In fifteen minutes the car was practically a wreck, even the engine in front being so badly damaged that it was useless.

The tides of Puget Sound, however, have a rise at times of fully eight feet, so it is necessary to lift the keel at least this distance above the surface of the water. In all, less than 100 horse-power are required to raise and lower the dock. The photograph shows a clipper ship of 4,000 tons being repaired in the dock.

Moreover, it had to be as simple as possible in construction in order that it might be handled by even the inexperienced. This problem was successfully solved.
