To the Senate of the United States:
In compliance with the resolution of the Senate of the 19th ultimo, requesting information in regard to any plans to induce the immigration of dissatisfied citizens of the United States into Mexico, their organization there with the view to create disturbances in the United States, and especially in regard to the plans of Dr. William M. Gwin and M. F. Maury, and to the action taken by the Government of the United States to prevent the success of such schemes, I transmit a report from the Acting Secretary of State and the papers by which it was accompanied.
