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, Augu
