Mr. McMahon to Mr. Seward.
Sir: I have the honor to inform you that I have received from Mr. Worthington, United States minister resident to the Argentine and Oriental Republics, the assurance that the allied governments engaged in the war against Paraguay will oppose no obstacle to my passage up the rivers Parana and Paraguay to my post of duty, and that they have issued appropriate orders to the generals commanding their respective forces.
The communication contaning this assurance, a copy of which I inclose, marked A, comes from the Argentine government, and was issued, it appears, upon consultation with the representatives of Brazil and the Oriental Republic.

I will leave for Paraguay this evening on the United States steamer Wasp accompanied by Admiral Davis. Three other vessels of the squadron passed this port to-day on their way to the Parana.
No change in the military position has taken place since my last dispatch. The allies have not yet attacked the position of President Lopez at Villeta.
I have the honor to be, very respectfully, your obedient servant,
Hon. William H. Seward, Secretary of State, Washington, D. C.
