Uessrs. Editors True DeLta Our semi-monthlv
connection with the United States which, by reason
OF the infrequency and costliness of this communi-
cation seems foreign country to us, enables me-
after long silence, to again apprise you of passing
events upon this frontier
About two weeks ago force of four hundred
raw Mexican recruits, started under Col. Guada-
lope garcia, to assist on attempt to take Tampi
co from the Centralists. They have not been heard
| from; but only the most creduous expect them to
| make much Roadway against a garrison of reg
! uars.
| But a much more important decree of the COVER
| nor OF the State of Tamauipas has TRANSFERRED 1t
| is no less than declaring all the ports on the Rio
| .Grande and indeed its whole shore and for some
twenty miles into the interior free for the importa
ton OF all goods, which to pay duty only when
they are carried beyond this ''free zone" it is
called. As Gov. Cara (Csarza) is acting in concert
| with Gov. Nidaurr of Nueva Leon, the gentleman
! (Sen. Cavazos) who obtained this concession from
! Gov. q. has gone to seek the concurrence of v,
and, that procured, will find, in exchange for the
| late oppressive, cumbrous and deadening Mexican
tariff, belt of country twenty miles wide. of the
richest alluvion, watered by a river navigable now
for five hundred miles the year round with taxes
whatever upon its commerce, its manufactures its
! products, or any of its industrial pursuits.
| With such advantages | cannot see why, let it
continue but five years. the Mexican side OF the Rio
Grande should not be settled with a most thrifty,
| prosperous energetic, improving population, who
with English and French and German goods laid
down free of duty, as well those of the United
States, will have largely the advantage of their
neighbors on this side, who will be paving from 20
! to 30 per cent. in duties for the same goods
/ Vidaurri and GAIA Nueva Leon and Tamaulipas
are now Independent of Toloaga and Mexico We
think they can maintain their independence and if
they cannot otherwise they will ask the protection
OF the United States, without the Union if possible
II not, within it. For this | have high authority
FIRE-ARM INvEXT1oS-Mr Sauerbery. of Switzer-
land, Is the inventor of new firearm device,
slstng OF hollow cylinder of steel other mccall
OF diameter slightly smaller than the inside of the
barrel intended to be rided hecordially The two
ends of the cylinders are warmed inside; into one
end Is screwed rod by means of which the cylin-
der is worked and the other end receives
destined to drag in its motion priSmatic mandril
This mandril is slotted and followed at its largest
part to bind itself with the end of the screw
for transmitting to the mandr a movement of lon
gitudina sliding when the is turned by press
ing spindle in its hole. At about half the length
of the hollow cylinder, three openings are made
through its thickness, IN which are placed three
dies, the under part of which comedies in the inside
sides of the mandril. The dies are of cast steel
tempered, and have outside cutting projections dis
disposed in a spiral line.
The mandril being pushed towards the extremity
of the followed cylinder, its point causes the ont
ting parts OF the dies to project but very slightly
from the cylinder, and in proportion as the mandr
pushed forward by turning the screw the emitting
parts will project more and more Conseouentiy
by passing the followed cylinder, as described IN
the barrels OF guns, pistols &c. and by pivinp to
1t the suitable helical motion there is obtained at
the same time all the helical grooves which, till
now, were made one after the other
