DEAR SIR,--You are not unapprized that in order to check the evasions of the embargo laws effected under color of the coasting trade, we found it necessary to prevent the transportation of flour coast-wise, except to the States not making enough for their own consumption, and that to place the supplies of these States under some check, a discretionary power was given to the Governors to give licenses to the amount of what they deemed the necessary importation. By a subsequent regulation, the collectors were advised not to detain suspicious vessels, the articles of whose cargoes were so proportioned as not to excite suspicion of fraudulent intentions; and particularly where not more than one-eight in value was provisions. This last regulation has operated so well that in the other importing States (Massachusetts excepted) little or no use has been made of the power of giving special licenses. But the licenses of Massachusetts, in the first two months, having amounted to 60,000 barrels of flour, the quantity was so much beyond their consumption, that it was suspected the licenses were fraudulently perverted to cover exportation. I therefore requested Governor Sullivan to discontinue issuing them, as, if the whole quantity was landed and retained in the State, it could not want for some time, and if exported, it showed we ought to guard that avenue to fraud. He apprized me, however, by letter, of circumstances which induced him to continue a moderated issue of licenses till he could hear from me, and I approved of his doing so till he should leave the capital, which he informed me he should do in the fall, when, if the power were to be continued, he wished it to be put into other hands, as his absence would prevent his exercising it. On this ground the matter now rests. He supposes that about ninety thousand persons in the State subsist on imported flour, which, at a pound a day, would require between thirteen and fourteen thousand barrels a month. Certainly it is not my wish that the want of a single individual should be unsupplied a single day; and I presume the well-affected citizens of Massachusetts would not wish, by importing a superfluous stock, to open a door for defeating a law judged by the national authorities necessary for the public good, and cheerfully submitted to elsewhere in the union. The question is, whether, after so great importations, the permission to all coasting vessels to take one-eight in provisions will not supply the State? On this subject I ask your friendly information. If it will not, then I must request your undertaking to issue licenses, on the departure of the Governor, to such characters as you may not suspect would make a fraudulent use of them. The power will, with propriety, devolve on you, on the Governor's declining it. You stand next in the confidence of the State, and certainly second to no one in my confidence. I will therefore ask from you a full
