New York City was made by Charles Goodale on July 19. He flew from
Palisades Park on the Hudson and return.

From a scientific toy the Flying Machine has been developed and
perfected into a practical means of locomotion. It bids fair at no
distant date to revolutionize the transit of the world. No other art
has ever made such progress in its early stages and every day witnesses
an improvement.

The air, though invisible to the eye, has mass and therefore offers
resistance to all moving bodies. Therefore air-mass and air resistance
are the first principles to be taken into consideration in the
construction of an aeroplane. It must be built so that the air-mass
will sustain it and the motor, and the motor must be of sufficient
power to overcome the air resistance.

A ship ploughing through the waves presents the line of least resistance
to the water and so is shaped somewhat like a fish, the natural denizen
of that element. It is different with the aeroplane. In the intangible
domain it essays to overcome, there must be a sufficient surface to
compress a certain volume of air to sustain the weight of the machinery.

The surfaces in regard to size, shape, curvature, bracing and material,
are all important. A great deal depends upon the curve of the surfaces.
Two machines may have the same extent of surface and develop the same
rate of speed, yet one may have a much greater lifting power than the
other, provided it has a more efficient curve to its surface. Many
people have a fallacious idea that the surfaces of an aeroplane are
planes and this doubt less arises from the word itself. However, the
last syllable in _aeroplane_ has nothing whatever to do with a flat
