APPENDIX. 
sent. On examination, although satisfied with the provisions of the treaty, 
they were fearful of future difficulties that might arise from the ambigui- 
ty of certain passages, and declined to approve it, stating the clauses to 
which amendments were solicited. 
The treaty was sent back to Mexico. In the mean time- a new election 
for the Presidency of that Republic had been held ; a new President inau- 
gurated ; a new Cabinet formed. On the application for amendment of 
the treaty, the requests of the grantees, through their Government, were 
favorably considered, many of them accorded, and a new treaty negotia- 
ted. During this entire negotiation not a hint was thrown out, not a sug- 
gestion made, indicating on the part of either of the two Presidents of 
Mexico, or any member of the two successive Cabinets, a doubt as to the 
entire validity and binding force of the grants and decrees above related, 
nor as to the titles of the present holders. And it is, perhaps, worthy of 
remark, that they were both negotiated in the city of Mexico, by Manuel 
G. Pedraza, an ex-President of that Republic, and at that time President 
of the Mexican Senate. 
The second treaty was sent to this country for approval and ratification, 
and on the 18th February, 1851, the following letter was written, viz. : 
Department of State, 
Washington, 18th February, 1851. 
To P. A. Hargous, Esq., Washington : 
Sir — I have to inform you that a convention between the United 
States and the Mexican Republic, relative to a transit way across the Isth- 
mus of Tehuantepec, was signed in the city of Mexico on the 25th ultimo. 
As its twelfth article requires that the holder of the grant conferred by 
the Mexican Government, pursuant to its decree of the 1st March, 1842, 
shall file his assent to the convention in the office of the Mexican Minister 
at Washington, before the instrument shall be "submitted to the Senate of 
the United States, you are requested to call at this Department for the 
purpose of examining the convention. 
I am, sir, very respectfully, your obedient servant, 
Daniel Webster. 
In compliance with this invitation, the treaty was examined by Mr. 
Hargous, and approved for himself and in behalf of the company. The 
treaty, together with the titles to the grant, were submitted to the Senate, 
unanimously approved and ratified, and the treaty was engrossed, signed, 
and returned. 
In the mean time, and before the treaty had been sent back to Mexico,
