Mr.. Enron. Please give place to the following ex-
tracts from the ST. Louis Union, democratic paper,
They contain some Items that may be new TO many
of your readers.
Several very important inventions have recently
been patented. One of them is an improvement in
steam-bolers by James Montgomery, Of Tennessee.
! am not mechanic enough TO give you clear writ
ten description of this invention, and can only say
that ii consists of boiler of novel construction,
forming, as II were a complete honey,com of fiues
of course OF smaller size than the fiues now used
and vertically instead Of horizontally The nven-
tor claims that will fifty per cent in fuel will
occupy much less room than the old style boiler, and
will weigh much less and generate steam faster
and, above ALL 81" will not blow up under any crcun-
stances" II possesses many other advantages
which cannot now enumerate. 1t is very highly
recommended by Professor Renwick, of New York
| and by number of extensive Engine builders in
that city, and also by Capt Shreve, of ST. Louis
As this is matter of interest to large portion Of
your citizens, ! wasld refer them to a late number
| oil Hunts Merchants Magazine, in which they will
find full description of this important invention
But steam is longer to be used as motive pow
err. Mr. James P. Egan, of Dresden, Ohio, has Just
filed caveat for an invention for propeng machine
ny by Electro-Magnetism. This consists of what
he terms contraction magnet" being series OF
| circular magnetised plates connected In such man.
ner as to admit of their being drawn apart to given
distance, or closed up like rod of solid metal
These plates are aernated with solid metal of the
same diameter, and together they form piston
which works in pelx answering to a cylinder
which being properly charged with electricity, forces
out the piston which forces itself back apa NV the
magnetic power within 1t, and thus, power Is OBJ
tanned which can be increased TO any required ex-
tent Machinery for the contraction magnet will
require neither boilers or fuel and of course will be of
great saving In cost and bulk, and besides, there
cannot possibly be an explosion. II can be worked
cheaper than steam This know Is hard 10 swa-
low but the inventor demonstrate the practicable
lily and utility Of his machine with as much facility
as ever did Fulton, the Steam Engine.
Another late invention Is one patented two or
three days ago, by citizen of ST. Louis II il an
Improvement in sadderees, and has attracted great
and will be adopted by the Government for the ORA,
COON and Calvary service II was patented BY Col,
Thornton Grimsley, who is now in this city.
BY the bye, the Colonel receives q great deal Of
attention. He has been the guest Of Mr. Benton and
Of several other distinguished personpges without
regard TO politics. ! him few days ago, In
company with another former citizen of your place.
Lewis +. Thomas, the poet; known in 81. Louis as
'Rhe Gentleman in biack'') he is now living here,
practising law and keeping an agency for Patents
and soldiers claims &c, and looks as well us ever
and yet another well known sometime citizen of ST
Louis, Is often seen among us, J. Larkin Dorsey
zone OF The People, he used to be styled from his
signature TO some Wing pamphlets which exhibited
great research and much talent. Mr.. d. was an
unsuccessful candidate for the Legislature in Prince
Georges county, Maryland, at the late election. We
have quite n colony Of Missourians here, and the
Mastodon State is always well represented In the
metropolis ofthe Union. &~
Mr.. Dorsey, alluded TO above, was for some time
resident in ST. Louis, Missouri, and well known TO
the writer an able, efficient and incorporating
Wing. His frequent speeches while there were al
ways listened TO with great attention and were re-
markable for their political statistics and their depth
of reasoning. His pamphlet, "One Of the People,

cratic nisrnle and had great influence throughout
the STATES II Missouri and Illinois After Mr.. d.
removed 10 this City, be became in 1874 Of the
most prominent Wing partisans in this vicinity and
his pen produced the strong and vigorous pamphlets
which emanated from the Washington Wing Com
