Mr. Sanford to Mr. Seward.
Sir : With reference to my No. 403, I have the honor to enclose herewith, in continuation, an exposé of the negotiation respecting the works undertaken by Holland in the Scheldt, which was submitted yesterday to the House of Representatives.
The French and English engineers who are to investigate this subject, at the request of Belgium, have already left for Holland ; the Prussian engineer is about to proceed there, and their opinions will, doubtless, soon be submitted to this government.
I have the honor to be, with great respect, your most obedient servant,
Hon. William H. Seward, Secretary of State, Washington, D. C.
