he can pass trains in four days. I will at once direct best possible arrangements to work from this end. You will please advise, when proper to do so, whether we can depend upon obtaining the materials from Harper's Ferry. You are doubtless aware that in case of necessity we can send trains from Washington to the Monocacy River in five hours, and from Baltimore in four hours.
