If a small weight is placed at the pointed end, and it is projected through the air, it will fly straight, and is but little affected by cross currents. The A-shaped disposition of the planes, gives it good lateral stability, but it has the disadvantage under which all aeroplanes labor, that the entire body of the machine must move on a fore and aft vertical plan in order to ascend or descend.
As a rule, it is handled and petted by the children from the time of its birth, and hence its taming and breaking is a matter of little moment. In the mountain region about Lakub, where most of the animals are allowed to run half wild, only the strongest are broken. The animal is driven into a A-shaped pen, and a heavy pole is fastened across its neck just behind the horns.
The load is strapped with a rawhide to a double A-shaped frame which fits loosely over a second saddle on the animal's back and is held in place by its own weight. If a mule falls the pack comes off and, moreover, it can be easily removed if the road is bad or whenever a stop is made.
It seems to be a form which has equal stabilizing powers whether at slow or at high speeds, thus differing essentially from many forms which require a certain speed in order to get the best results. RACING MODELS. Here and in England many racing models have been made, generally of the A-shaped type, which will be explained hereinafter.
West of this about ten miles, where we had killed some deer earlier, we made a A-shaped cabin and made dead falls many miles around to catch fishes, foxes, mink and raccoons. We made weekly journeys to the places and generally staid about two nights.
Sometimes we thrill with the "honk, honk" of the Canada goose and think the A-shaped band of migrants is surely this year's messenger, crying in the wilderness to prepare the way of the goddess and make her paths straight; but a little later we pass through a shadowy ravine where the white oaks have held their leaves all winter, and find that the great horned owl has already appropriated a last year's hawk's nest and deposited therein her two white eggs.
On account of the lateness of the season and the rocky, precipitous, and extremely dangerous character of the coast in the vicinity of Gizhiga, the captain of the bark had not deemed it prudent to run into the mouth of the Gizhiga River at the point of the long A-shaped gulf, but had anchored on a shoal off the eastern coast, at a distance from the beacon-tower of nearly twenty miles.
Unlike the large aeroplanes, the supporting surfaces, in the models, are at the rear end of the frames, the pointed ends being in front. A-Shaped Racing Glider.
The favorite method of locomotion is to pole or, when the wind favors, sail. The mast is an A-shaped contraption, twelve feet high, made of two light poles tied together and fastened, one to each side of the craft, slightly forward of amidships.
The A-shaped roof was thatched with small branches laid close together and over these long jungle grass and palm fronds, with a final coating of clay.
