AVIATION DEVELOPMENT.

The wonderful progress made in the science of aviation during the year 1911 far surpasses any twelve months' advancement recorded. The advancement has not been confined to any country or continent, since every part of the world is taking its part in aviation history making.

The rapidly increasing interest in aviation has brought forth schools for the instruction of flying in both the old and new world, and licensed air pilots before they receive their sanctions from the governing aero clubs of their country are required to pass an extremely trying examination in actual flights. Exhibition flights and races were common in all parts of the world during 1911, and touring aviators visited India, China, Japan, South Africa, Australia and South America, giving exhibitions and instruction.

Europe was the scene of a number of cross-country races in which entries ranging from ten to twenty aviators flew from city to city around a given circuit, which in some instances exceeded 1,000 miles in distance. Cross-country flights with and without passengers became so common that those of less than two hours' duration attracted little attention. There were fewer attempts at high altitude soaring, although the world's record in this department of aviation was bettered several times. In place of these high flights, the aviators devoted more attention to speed, duration and spectacular manoeuvres, which appeared to satisfy the spectators. The prize money won during 1911 exceeded $1,000,000, but owing to the increased number of aviators the individual winnings were not as large as in 1910.

It is estimated that within the past twelve months more than 300,000 miles have been covered in aeroplane flights and more than seven thousand persons, classed either as aviators or passengers, taken up into the air. The aeroplane of today ranges through monoplane, biplane, triplane and

even quadraplane, and more than two hundred types of these machines are in use.

Aeroplanes are becoming a factor of international commerce. The records of the Bureau of Statistics show that more than $50,000 worth of aeroplanes were imported into, and exported from, the United States in the months of July, August and September, 1911. The Bureau of Statistics only began the maintenance of a separate record of this comparatively new article of commerce with the opening of the fiscal year 1911-12.

Two of the prominent developments of 1911 were the introduction of the hydro-aeroplane and the motorless glider experiments of the Wright brothers at Killdevil Hills, N. C., where during the two weeks' experiments numerous flights with and against the wind were made, culminating in the establishing of a record by Orville Wright on October 25, 1911, when in a 52-mile per hour blow he reached an elevation of 225 feet and remained in the air 10 minutes and 34 seconds. The search for the secret of automatic stability still continues, and though some remarkable progress has been made the solution has not yet been reached.
