WAR DEPARTMENT, May 29, 1842.

Brigadier-General EUSTIS,

Boston.

SIR:  The governor of Rhode Island has represented to the President that preparations are making in other States (particularly in Massachusetts) for an armed invasion of that State to support the usurpations of Mr. Dorr and his friends and foment domestic insurrection.  It is very important that we should have accurate information on this subject, and I have to desire you to take all necessary means to acquire it, and communicate directly to me as speedily and frequently as possible.  It is said that 1,000 stand of arms have been procured in Boston, some pieces of artillery, and a large quantity of camp equipage for the use of the insurgents.  Your attention to this is particularly desired to ascertain its truth or falsehood.  It is also said that there are 200 men enrolled and embodied in a town upon the borders of Rhode Island, the name of which has escaped me.  Please inquire into this.  If it becomes necessary to employ confidential persons to discover what is doing, you will do so, being careful to select those only that are entirely trustworthy; and it will be desirable to avoid heated partisans on either side.  Their inquiries should be conducted quietly and privately.

I desire you to communicate fully and freely what you may learn and your views concerning it for the information of the President and the Department.

It is scarcely necessary to say that this communication is strictly private and confidential.

Respectfully, your obedient servant,

[J.C.  SPENCER.]

NEW YORK, June 3, 1842.

The PRESIDENT.

MY DEAR SIR:  I came to this city yesterday, having taken a severe cold on the Sound, and am now just out of my bed.  I transmit herewith a letter from ——­, a friend appointed by me, as you requested, to look into the Rhode Island business.  Mr. ——­ has had access to authentic sources in Governor Dorr’s party, and I have no doubt his account of the whole matter is perfectly just.  I supposed I should receive the foreign mail here, but I shall not wait for it if I should feel well enough to travel to-morrow.

Yours, truly,

DANL.  WEBSTER.

NEW YORK, June 3, 1842.

Hon. DANIEL WEBSTER,

Secretary of State.
