Lotteries have of late been a very productive source of revenue in this State.--The moral tendency of them has been supposed by some to be injurious to society; and government have been careful to grant them for such purposes only, as that the probable benefit should outweigh the evil. By this means we have seen the interests of literature supported--the arts encouraged--the wastes of war repaired--inundations prevented--the burthen of taxes lessened, &c.

There exists a spirit of adventure in all societies, which will lead a number to throw themselves into the hands of Chance in one way or another, & which, under the direction of a wise Legislature, may be made to subserve their best interests. The monies raised by lotteries cannot impoverish the community--as they are not sent abroad, but only taken out of one pocket and put into another. * * * * * There is also in the same paper, of Feb. 25, 1794, another communication, in which the writer apparently takes an entirely opposite view, and quotes a letter of Joel Barlow to the National Convention of France, in which will be found some rather strong language.

It is as follows:
