New Treaty with meIico-The Route to Calf
fornia by the Tehuantepec Isthmus.
Mr.. Letcher, the American Minister at Mexico
has been announced, has succeeded in effecting
treaty with the government of that country, with
respect TO the Tehuantspec route across the 18TH

its character and conditions, that recently made
by our efficient Charge d'Affaires, Mr.. Squier,
between our government and that OF Nicaragua

decree of the first Of March, 1912; and in that of
Mariana de Salas, dated the fifth Of November
1S46. The former decree contained eleven articles;
and the third Of the series declared that the pas
sage across the Isthmus should be neutral and
sommon to all nations at peace with Mexico The
government generally made this whole decree,
upon certain terms, with Don Joee de Gsray who,
h appears, has surrendered, in some way, all the
concessions originally made to him, to certain citi-
zens of the United States residing at New Orleans.
by way Of distinction, therefore, this may be term
cd New Orleans enterprise, though the results
may be Of national importance. The treaty was
made the twenty-fourth of last month, and it 10
calculated to call forth much discussion. as well as
TO excite great interest in every part of the country
For many years the idea ofmaking an easy route,
either by railroad or canal, between the Pacific
and Atlantic oceans has arrested the attention. not
emily of our countrymen, but the serious in
eury Of several European governments. A ship
railroad, with a capital Of ten millions Of
pounds sterling, was proposed, at one time, in
London, with a view OF levyng tolls upon all the
nations Of the earth This was gigantic scheme.
When the mind contemplates the possibility Of
taking a ship into a dry dock on the Atlantic
shore, Of crsdling il upon with forty-eight
wheels, running upon eight rails, Of seeing il
transported across the country, and deposited in a
dock upon the Pacific, the ingenuity OF man be-
comes an object Of admiration. We are startled
with its boldness-though we can scarcely doubt
the raiisnaliiy Of its resources. Vast capital
accomplish vast results. However, the English
plan will not be carried into effect in the present
century. The French and the Germans have
made several surveys Of different routes, az well
Is the English and Americans. That by Tehuan-
tepsc, may or may not be practicable. Senior
Gattano Moro's survey gives a highly favorable
picture Of the country, for the proposed road.
From his surveys, il seems that the entire dis
lance from Tea TO sea, is one hundred and thirty
1--WE miles, ia a right line II presents a wide plain
from the mouth Of the Coasacoalcos TO the foo, of
the Mesa de TARIFF, which is table land, rising
to siI hundred and fifty feet above the level Of the
sea, and, AZ five miles distance, descends again to
the plain which reaches the Pacific Near Tehu-

ships may find harbors in these waters From
the inner LAKE. the land rises very gradually Ia the
Venta de Chicaps, thence with sleeper .cclivty
upon Tarifa-snd there is a slight declvity to a
nver, which is navigable for ships for the distance
Of thirty four miles from its mouth on the Giir of
Mexico. Such the rude outlines Of Moro's
survey.
The resources Of the country are immense for
timber % the beet quality, for building a road.
The facilities for cattlefeedng are complete. The
coil is prolific, and salt mines are absndant. The
climate is agreeable and mild, and usually salu-
brious. The advantages, therefore. for construct.
ing a road, cannot be overlooked. In a com
mefeial and political point Of view however, such
a road would be very desirable, and, could Il be
made, would add largely TO the prosperity Of our
country. From the mouth Of the Mississippi to
San Francisco, by Tehuantepec, is one thousand
eight hundred and twenty-five miles nearer than
by Pansma. From New York, fourteea hundred
miles Of sea navigation would be saved, were ts,
route opened.
Such are the most obvious advantages Of this
route. Others, though not so specifically ap1a-
rent, VIII readily rise, upon investigation. The
Gsh OF Mexico lies chiefly within the jurisdistion
OF those who would be interested in this route.

carried on, withou, any serious apprehension Of
disturbances Gor foreign powers. Th. alone Is not
an unimPofiant consideration. and will, we doubt
no', be amply rejected upoa BY our Senatorial body,
