I have just received a deputation from the Alexandrians, who are under uneasiness for their own unprotected situation, and asking the loan of a large number of muskets and cannon. I have convinced them that a very small force at Digges' Point will defend them more effectually than a very great one at their city, and that on your return we will have the place examined, a battery established, and have small arms in readiness to be given out to them in the moment they shall be wanted to support the battery. Indeed I think a position to be taken there is indispensable for the safety of the Navy Yard and its contents: say a battery and block-house. Who can we get to examine the place, and give a proper plan? This we must determine on your return. Nothing new from Norfolk. Mr. Erskine has written pressingly to Commodore Douglass. Affectionate salutations. TO MR. GALLATIN. July 10, 1807. Something now occurs almost every day on which it is desirable to have the opinions of the heads of departments, yet to have a formal meeting every day would consume so much of their time as to seriously obstruct their regular business. I have proposed to them, as most convenient for them, and wasting less of their time, to call on me at any moment of the day which suits their separate convenience, when, besides any other business they may have to do, I can learn their opinions separately on any matter which has occurred, also communicate the information received daily. Perhaps you could find it more convenient, sometimes, to make your call at the hour of dinner, instead of going so much further to dine alone. You will always find a plate and a sincere welcome. In this way, that is, successively, I have to-day consulted the other gentlemen on the question whether letters of Marque were to be considered as written within our interdict. We are unanimously of opinion they are not. We consider them as essentially _merchant vessels_; that commerce is their main object, and arms merely incidental and defensive. Affectionate salutations TO MR. BOWDOIN. WASHINGTON, July 10, 1807.
