The frame is entirely separated from the chute, acting merely as a supporting device to hold it, first, while it is being loaded, and later as a dumping device. This framework merely rests on the car across both sides.
When sufficient material has been taken from the car, the frame is tipped and the rear end is allowed to rest on the bottom of the car. This permits the

WIRELESS FOR AIRSHIPS.
According to the connections of the aerial and the complete set it will be noted that, when sending out the electrical waves, the alternating currents will radiate in every direction and will travel in proportion to the strength and capability of the set in regard to transmission. The system, if adopted by air-men, will give better results high in the air where there is little of atmospheric disturbance and therefore greater and better results can be accomplished. The distance in the air will be three to four times as great with the same set than if used on land.
THE LEAF OF THE SUNDEW. Here is an interesting example of a device used by a plant to catch its insect food. There is a little sweetness in the center of the leaf and when a fly alights it is caught by the quick turning in of the tentacles. These hold the fly in position until it is digested, that is until actually eaten by the plant.
TRACTION THRESHING MACHINES OF A NEW SORT.
There is a man in Skowhegan, Maine, who has invented a traction threshing machine. The power is a gasoline engine and it is moved about by its own power with the separator which is built on a jigger of the four-wheeled delivery cart style. In moving the threshing machine from place to place it travels at the rate of about four miles per hour. It threshes grain faster than it can possibly be threshed with the old fashioned threshing machine with horses.
the aid of the rubber tires, which prevent the escape of the high tension oscillating currents through the frame and wheels, thereby insuring a perfect ground insulation, the experimenters were enabled to communicate for the distance of about 372 miles without a ground connection. The experiment took place along the banks of the Charles River with Jonescick Brothers at the foot of the Cambridge Bridge and Mr. I. Wolff at the foot of the North Harvard Street Bridge.
TEETH OF AQUATIC ANIMALS HERE is an assemblage of the teeth of
some aquatic animals—interesting if only for the reason that they are so different.
For instance, the two outside ones are the tusks of a walrus. They are the upper incisor teeth of the beast, and are not intended for chewing, but for defense.
All through creation is found the most astonishing adaptation of teeth to necessity. Thus the mighty ivory lance of the narwhal, ten or twelve feet long and strong and sharp enough to be driven through the side of a ship, is simply the left upper incisor of the creature. Once in a while, by a freak, both upper incisors will be developed in the narwhal, so that it is equipped with two spears instead of one. The female has no lance.
Likewise, the tremendous ivory spear of the swordfish is merely a gigantic tooth developed for fighting purposes.
