I return you the pamphlet of the author of War in Disguise. Of its first half, the topics and the treatment of them are very commonplace; but from page 118 to 130 it is most interesting to all nations, and especially to us. Convinced that a militia of all ages promiscuously are entirely useless for distant service, and that we never shall be safe until we have a selected corps for a year's distant service at least, the classification of our militia is now the most essential thing the United States have to do. Whether, on Bonaparte's plan of making a class for every year between certain periods, or that recommended in my message, I do not know, but I rather incline to his. The idea is not new, as, you may remember, we adopted it once in Virginia during the revolution, but abandoned it too soon. It is the real secret of Bonaparte's success. Could H. Smith put better matter into his paper than the twelve pages above mentioned, and will you suggest it to him? No effort should be spared to bring the public mind to this great point. I salute you with sincere affection.

TO THE HONORABLE JOHN SMITH.

Monticello, May 7, 1807.

Dear Sir,—Your two letters of March 27th and April 6th have been received. Writing from this place, where I have not my papers to turn to, I cannot even say whether I have received such as you ask copies of. But I am sorry to answer any request of yours by saying that a compliance would be a breach of trust. It is essential for the public interest that I should receive all the information possible respecting either matters or persons connected with the public. To induce people to give this information, they must feel assured that when deposited with me it is secret and sacred. Honest men might justifiably withhold information, if they expected the communication would be made public, and commit them to war with their neighbors and friends. This imposes the duty on me of considering such information as mere suggestions for inquiry, and to put me on my guard; and to injure no man by forming any opinion until the suggestion be verified. Long experience in this school has by no means strengthened the disposition to believe too easily. On the contrary, it has begotten an incredulity which leaves no one's character in danger from any hasty conclusion. I hope these considerations will satisfy you, both as they respect you and myself, and that you will be assured I shall always be better pleased with those cases which admit that compliance with your wishes which is always pleasing to me. Accept my salutations, and assurances of great esteem and respect.

TO MR. MADISON.

Monticello, May 8, 1807.

I return you Monroe's letter of March 5th. As the explosion in the British ministry took place about the 15th, I hope we shall be spared the additional embarrassment of his convention. I enclose you a letter of Michael Jones for circulation, and to rest with the Attorney General. It contains new instances of Burr's enlistments. I received this from Mr. Gallatin, so you can hand it to General Dearborne direct.

I expect to leave this on the 13th, but there is a possible occurrence which may prevent it till the 19th, which however is not probable. Accept affectionate salutations.

TO MR. HAY.

Washington, May 20, 1807.
