OF THE WORLD'S INDUSTRY. 69
by several gold medals in the United States. How far this application of his invention
may be superior to the methods now in use for the same purpose is uncertain. In the
minds of sailors there is always an objection to fixtures above deck, which would be likely
to impede their general introduction.
Together with daguerreotypes, before alluded to, there were exhibited camera obscuras
by C. C. Harrison, of New York, the results of which, in the pictures that hung above
them, were exceedingly favourable. There were shawls from the Bay State mills, of
beautiful colour and a high perfection of manufacture; white cotton goods, which, in
bleaching, finishing, and putting up, appeared equal to Manchester products; some very
beautiful flannels, single-milled doeskins and wool-black cassimeres of thorough fabric;
tweeds, well mixed and of good colours; a salamander safe, well made; Newell's improved
bank lock, ingenious and well constructed; a patent paying-machine for pitching the
seams of vessels, the box being provided with a ventricle wheel, which receives the hot
melted material, and applies it neatly, economically, and directly to the seam to be
covered; an air-exhausted coffin, with glazed aperture at top, a most whimsical idea, but
whether for the benefit of the defunct to look out, or the survivors to look in, we were
at a loss to determine. Next came a host of "notable things." Car wheels for railroads,
wood and cork legs, clocks, watches, dentists' tools and works, India-rubber goods of
various forms, mathematical and solar instruments, a self-determining variation compass,
trunks, boots and shoes, hats, specimens of printing aud binding, together with pistols,
rifles, and other weapons of offence and defence. Of these rifles, manufactured by
Bobbins and Lawrence, it is but just to say that they are among the best, if not the
best, of any rifles manufactured in the world, the Americans claiming to excel in this
species of manufacture. They are made from the best selected Copake cold-blast forge
iron, and are of an unpretending style, but remarkable for a plain, substantial, and
perfect finish; they are strong, simple, and thorough in their workmanship, and
eminently adapted for real service.
Two bell telegraphs, exhibited in the central avenue, very deservedly attracted much
attention. The bell telegraph, otherwise called an " annunciator," is an invention
made to supersede the awkward array of bells in houses and hotels. It is an extremely
neat and beautiful article, and indicates whence the bell was rung, by uncovering a
number corresponding to the number of the room; and this, too, for any length of time
afterwards, until, by the touch of a spring, the number is re-covered. In the large
hotels in the United States, and in many private residences, it is much used.
In the moving machinery department, among other objects of interest from the United
States, was a machine exhibited by*Mr. Charles Morey, called a stone dressing machine.
A machine for dressing stone by power has long been regarded as a great desideratum,
and has been the object of many expensive, though unsuccessful experiments. One
great difficulty has been found in making the cutting tools of a quality to stand the
action of stone, unless at such cost as to render their use unprofitable. This difficulty
is overcome by the present invention, which consists in the employment of chilled cast-
iron burrs, or rolling cutters. Iron, as is now known, may, by a peculiar process of
chilling in casting, be converted to a diamond hardness, that perfectly fits it for reducing,
with great facility and economy, the surface of stone. The burrs made in this way
retain a sufficient degree of sharpness for a long time, and can be maintained at a
small cost, being wholly formed and finished in casting. In dressing circular forms, the
stones are made to revolve, when the burrs, which are mounted in sliding rests, are
brought into action. For straight surfaces, however, the stones are laid upon a trans-
verse bed, and the cutters, mounted upon a revolving cylinder, are placed above them.
The burrs or cutters are so arranged as to turn freely on their axis when brought in
by several gold medals in the United States. How far this application of his invention
may be superior to the methods now in use for the same purpose is uncertain. In the
minds of sailors there is always an objection to fixtures above deck, which would be likely
