Chemistry for Aeronauts. British aeronauts will be interested to learn of a useful development of invention as applied to practical ballooning which can hardly fail to give the science a strong practical lift forward. A German inventor, Captain von Krogh, who acted as a pilot of the Parseval balloon, has devised a means for dispensing with ballast in bulk. Instead of sand, certain chemicals of a non-bulky nature are used. These have the property of absorbing moisture from the atmosphere and thus of increasing their weight. The invention was tried with complete success in a voyage from Tegel to Koeslin, a distance of 186 miles, which was covered in about six hours. Journal Atlanta 15 Ap-1907 Ga. MAN AND DAUGHTER HURT BY BALLOON Big Aerial Vesssel Falls On Two People As They Stood Watching Ascension. (Special Dispatch to The Journal.) BIRMINGHAM, Ala., April 15.--H. D. Keith, a prominent citizen of Bessemer, and his little daughter were injured in a most peculiar manner in an accident near their home. The two were out watching a balloon ascension by a carnival company showing there. When the balloon reached its highest point the aeronaut cast off from it and started down in a parachute. The two were intently watching the parachute, and never noticed the descending bulk of the balloon, which struck them, overturning their buggy and involving the horse, as well as the two occupants of the vehicle, in a mass of smoking cloth and network. Mr. Keith's injuries, as a result of the struggles of the frantic horse, were at first pronounced serious, but physicians now state that he will be out in a few days. Queencan New York 16 Ap-1907 "U.S. WILL FLY IN THE AIR IN 1917" So Says A.M. Herring, Inventor, in Address to New York Aero Club. "The United States of America will be all flying in the air ten years from now," were the cheering words of A.M. Herring, experimenter to the New York Aero Club, at its meeting last night. Mr. Herring says he's the more confident of this because he has just perfected the invention of a new metal lighter than steel and twice as strong. He's making this metal now out of magnesia, aluminum alloy, nickel, and some other things which you can't expect him to tell about because there are fortunes in it. "Anyway, we'll be soaring in aeroplanes anywhere we want to go by that time," he continued. "My metal is going to make it possible." The new aeroplane which Mr. Herring is now devising will sail a thousand miles, according to Mr. Herring, and will be "just as safe as a cyclone cellar." The experimenter was very heartily cheered by Dr. Thomas, Leo Stevens, and other Aero Club members who don't care if they have been on the wrong tack with their gas bags so long as somebody makes air navigation a household word and flying machines as common as baby carriages. They also cheered when Mr. Holland. of submarine boat fame, told them just how a bird flies. Coupling this information with Mr. Herring's invention it became plain to all the laymen present that all anybody will have to do, after the patents have been applied for, will be to step into an aeroplane and soar away. orm the body of in future all trials will be conducted over water, and specially prepared oil surface will be used for all cloth that may be necessary to use for the work. He says there is no deviation from the experiments of former years. The general outline of the machine will remain the same. Practically the propelling on the plane the motor.

Knabenshue Will Bring the Real Thing Here in September. Secretary Conger of the West Michigan State Fair association has closed the first contract for the special features on this year's exposition, securing the big feature of the week in A. Roy Knabenshue and his airship. The week of the exposition is Sept, 9-13, inclusive, and Mr. Knabenshue is to make an ascension each day, weather conditions permitting. Not only this, but he will bring with him a captive balloon, patrons being permitted to take a ride in the clouds on payment of a fee, and also two racing balloons, one of which will be operated by himself and the other by his assistant. Mr. Conger said in view of the fiascos attending previous airship events in this city and Detroit he and the association were rather cautions regarding Mr. Knabenshue. He entered into correspondence with secretaries of fairs in different parts of the country who had in previous years had Mr. Knabenshue's services and all spoke in high terms of the merits of the attraction. Under the contract Mr. Knabenshue is to bring his latest type of ship, which he is now building at his home in Toledo, and which, ninety-two feet in length, is nearly twice as long as that previously used by him. He readily signed the agreement under which he makes ascensions or receives no pay. Last year he appeared at some of the biggest state fairs in the country and Mr. Conger says he lost but five days out of forty-three and these owing to unfavorable weather conditions. Mr. Conger believes this at-traction will be highly appreciated by the patrons of the west Michigan fair, as it was at Brockton, Mass., and other places Record Philadelphia 17 Ap-1907 STILL ANOTHER FLYING MACHINE Trials Made in France With Small Model Proved Quite Successful. -- HEAVIER THAN THE AIR -- French Inventor Busy on a Larger One He Intends to Enter in Competition. -- Another new flying machine known as the "Cornuce helicopter" is in the course of construction in France, where a series of successful trials have already been made with a small model. In this machine, which is of the "heavier-than-air" type, the ascentional power is provided by screws, but light canvas planes are used to assist in the flight. In the trials with the model apparatus the machine, which carries a two-horse power gasoline motor, rose readily in the air, the propeller having to lift a total weight of over 30 pounds. Monsieur Cornu, the inventor, proposes to build a larger machine on the same lines, and to enter with it for some of the aeronautic prizes which have been offered by different countries. These prizes are almost all the result of private interest in the subject of aerial navigation, as, for some unknown reason, Government officials of all nationalities seem to hold themselves somewhat aloof from such experiments. AN ENGLISH MODEL. Thomas Coop, an English engineer, is also constructing a new flying machine. The Coop machine, which is of the "heavier-than-air" type, too, is designed to rise by the direct lift of several propellers, and is not dependent upon the inclined plane which forms the basis of almost all inventions of this type. It is believed that by avoiding the use of the inclined plane, the danger so often met with, caused by sudden puffs of wind as the machine rises, will be obviated. The new machine has altogether eight flights of wings, the principal ones being in the centre of the top; while there are propellers fore and aft. side propellers to check the action of cross winds, and one at the bottom to help in regulating the descent. It is stated that much ingenuity has been devoted to the combining of extreme lightness with strength in constructing the Coop flying machine, which has a framework formed of bamboo. It is intended to carry three persons and two 20-horse power petrol engines. It is intended to carry three persons and two 20-horse power petrol engines. It will readily be understood that a very high degree of efficiency will have to be attained if the machine is to rise with this load under the influence of its wings alone. No trial trips seem to have been made as yet, and Coop's apparatus may be said to be still "all in the air," though not precisely in the manner its inventor intended or desires.
