Mr. Seward to Mr. Johnson

Insist on convention like 1853, without now naming arbiter. Convention must be submitted to Senate and the country. Objection would be raised to any arbiter who could be named in advance. When convention goes into effect, the two governments can instruct the commissioners to agree on arbiter.

WILLIAM H. SEWARD.

Reverdy Johnson, Esq., &c., &c., &c.
