orld, if he had a suitable position for his fulcrum, conveyed an
apt illustration of the measureless power of the lever when exerted to
its fullest extent. This fullest extent Mr Archard claims to have
attained in the action of a succession of parallel levers--one lever
upon a second, the second upon a third, the third upon a fourth, and
so on progressively; each succeeding lever of the same length as the
first, and all operating simultaneously, the one lever upon, and with
all the others. This marvellous property of multiplying leverage, is
attained without any diminution in speed, since, to whatever extent
the additional levers may be carried, the entire succession is moved
as one compact mass, operated upon at the same instant, the last lever
moving at the same moment with the first. This simultaneous movement
of a succession of parallel levers, acting the one upon the other,
with a force successively increasing and in geometrical proportion, is
the grand desideratum, the _ne plus ultra_, in the science of
mechanics, which the inventor professes to have achieved. To place
this multiplied _ad infinitum_ power in its plainest light, we may
observe that a given power--say that of one horse--will impart to a
lever of a given dimension a sixteenfold power; that sixteenfold power
gives the succeeding lever sixty-fourfold increase; that to the third
lever, 256; that gives to the fourth lever an increase of 1024; while
this fourth lever, with its largely increased ability, gives to the
fifth lever the enormous increase of 4096. If, therefore, this
succession of leverage is rightly stated, a single horse is enabled to
exert the power of four thousand and ninety-six horses!--_American

MY SPIRIT'S HOME.

Where is the home my spirit seeks,
Amid this world of sin and care,
Where even joy of sorrow speaks,
And Death is lurking everywhere?
Oh! not amid its fading bowers
My wearied soul can find repose,
For serpents lurk beneath its flowers,
And thorns surround its fairest rose.

The home of earth is not for me;
Far off my spirit's dwelling lies;
The eye of faith alone can see
Its pearly gates beyond the skies;
The ear of faith alone can hear
The music of its ceaseless song,
As nearer with each passing year
Its angel-chorus rolls along:

_There_ is the home my spirit seeks,
Above the fadeless stars on high!
Where not a note of
