Doc. 138.-President Lincoln's letter to the Maryland authorities.
Messrs. Bond, Dobbin and Brune, is received. I tender you both my sincere thanks for your efforts to keep the peace in the trying situation in which you are placed. For the future, troops must be brought here, but I make no point of bringing them through Baltimore. Without any military knowledge myself, of course I must leave details to General Scott. Ho hastily said this morning, in presence of  these gentlemen, “March them around Baltimore, and not through it.” I sincerely hope the general, on fuller reflection, will consider this practical and proper, and that you will not object to it. By this a collision of the people of Baltimore with the troops will be avoided, unless they go out of the way to seek it. I hope you will exert your influence to prevent this. Now and ever, I shall do all in my power for peace, consistently with the maintenance of Government. Your obedient servant,
--N. Y. Evening Post, May 6.
