l as a stronger engine; a larger as
well as a less hazardous propeller; and a natural condition of
resistance to the action of the elements; will make travel by water a
forcible rival to the speed attained upon land, and bring all the
distant countries in contact with our civilization, to the profit of
all. This metal is destined to annihilate space even beyond the dream of
philosopher or poet.

The tensile strength of this material is something equally wonderful,
when wire drawn reaches as high as 128,000 pounds, and under other
conditions reaches nearly if not quite 100,000 pounds to the square
inch. The requirements of the British and German governments in the best
wrought steel guns reach only a standard of 70,000 pounds to the square
inch. Bridges may be constructed that shall be lighter than wooden ones
and of greater strength than wrought steel and entirely free from
corrosion. The time is not distant when the modern wonder of the
Brooklyn span will seem a toy.

It may also be noted that this metal affords wide development in
plumbing material, in piping, and will render possible the almost
indefinite extension of the coming feature of communication and
exchange--the pneumatic tube.

The resistance to corrosion evidently fits this metal for railway
sleepers to take the place of the decaying wooden ties. In this metal
the sleeper may be made as soft and yielding as lead, while the rail may
be harder and tougher than steel, thus at once forming the necessary
cushion and the avoidance of jar and noise, at the same time
contributing to additional security in virtue of a stronger rail.

In conductivity this metal is only exceeded by copper, having many times
that of iron. Thus in telegraphy there are renewed prospects in the
supplanting of the galvanized iron wire--lightness, strength, and
durability. When applied to the generation of steam, this material will
enable us to carry higher pressure at a reduced cost and increased
safety, as this will be accomplished by the thinner plate, the greater
conductivity of heat, and the better fiber.

It is said that some of its alloys are without a rival as an
anti-friction metal, and having hardness and toughness, fits it
remarkably for bearings and journals. Herein a vast possibility in the
mechanic art lies dormant--the size of the machine may be reduced, the
speed and the power increased, realizing the conception of two things
better done than one before. It is one of
