Mr. Plumb to Mr. Seward
Sir: I have the honor to acknowledge the receipt of your personal instructions of the 7th instant, accompanied by my commission and passport as secretary of legation to the republic of Mexico.
The Hon. Lewis D. Campbell, minister to Mexico, and Lieutenant General Sherman arrived in this city late on the 8th instant. I reported that night to the minister, and, as at present advised, our departure for Mexico on board the steamer Susquehanna will take place at 2 p. m. to-day.
I am, sir, with the highest respect, your most obedient servant,
Hon. William H. Seward, Secretary of State, Washington, D. C.
