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.

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.

The most interesting improvement found on this motor and perhaps the most important advance made in the construction of aviation motors since the introduction of the revolving cylinder type, is
