Congress has adjourned, and passed the Cass-
Herran treaty, with some very important modiflca-
TONS very much to the regret of President
Ospeuis. These were made under the influence of
General MOsquera, the father-ln-law of General
Herran, who made the treaty with Gen. Cass But
for the influence of President Ospenia, who wrote
pamphlet on the subject In favor OF the treaty,
as it came from the United States, is doubtful if 1t
would have passed in any shape. The President is
very anxious to close up, in some shape, all the
difficulties that New-Granada has not only with the
United States, but Europe. On the adjournment
of Congress, the members and the population were
invited to examine the surveys and report made by
Capt Williamson, on the Cali and Bueno Fenturs
Railroad route. Among those who attended the
meeting was your correspondent, anxious 10 see
some of his cOuutrymens work, which has been
so highly spoken of in all parts of the country.
Much OF the indignation | felt against Gen. Mos
guerra for the part he took sganst the treaty, WAS
cooled off when / saw his tai form rise in the large
assembly present, viewing The surveys and explora
ton four miles on each side of the lines, as laid
down. There were 81 sheets of drawing paper,
feet long by 81 feet wide and profile Of the road
over 800 leet In length The General called the
assemblage to order; he rema hed that the surveys
explorations were made at his expense, IN behalf OF
the Company, ty Capt. John ID. Williamson, as
Engneer-ln-C chief, Of the children OF the great
North American Republic, gentleman whose fame
is we'll known in New Granada, and throughout
South America for his perseverance and energy in
exploring and bringing 10 public knowledge
the resources Of the continent New-Granada
owed him much for this vast work now
before them; and that work, which had
cuped 50 much time, care, attention and energy
for the last two years, with considerable corps of
engineers, and large number of laborers in the
field under Capt. williamson, had not cost the sum
Of $4,000. If it had been done in the United
States under any other engineer, with all the fac
ties there, il would have cost $4,000. Capt
Williamson deserved great credit for this beautiful
and correct survey and report, for the Army En-
glneers who were sent 10 examine II had So re-
ported To Congress. He congratulated the .cOmpa-
ny stockholders and our citizens that Capt Will
hsmson had been appointed Engineer-n-C Chief
His hope now was that he would accept the posi-
ton, aud the road under his perseverlng care and
energy would BE- completed in the time ne speci-
ned, as they had had any amount of money re-
quired to finish the road offered TO the Company
under bis direction, not only here but from Eu-
rope. After the General took his seat, Gen. No
reno of the House of Representatives made some
remarks about the survey and its importance 10
New-Granada, and also 10 the Panama Railroad.
And if Governments would lay aside their political
opinions in diplomatic appointments, and appoint
those who suited for the position, the difficult
ties which spring up between nations would be set
tied without the and of armies and nsvies. He
truly believed il the gentleman ut the head of that
survey had been Of the parties to settle the diff
hculties now existing between the two countries,
they would have been settled in 1857.
Z. S.-My next, / hope, will b. dated from
the region OF the Moss Emerald Mines, which
| shall visit next also the valley of the
Cauca to the south; also the Salt Mines Of
the interior. A friend at my elbow says
the reason of General Mosquerss opposition to the
treaty VAS because the Government here believed
the United States trying to destroy the trade
of the Isthmus, by compelling, in their Contracts,
all lines of steamers south Of the Isthmus 10 go
10 Tehuantepec when the route is opened, and all
the influence of the South to BE- put forth for the
support Of that route, So as 70 cut of the small
stipend New wGrsnsds is now receiving from the
Panama road; and my friend says that was the
reason the President used MS influence for the
treaty as il came from til United States 4.
