For the firstpurpose the South Caro1ina Legis1ature passed, in December, 1822, the Actfor the imprisonment of Northern co1ob1ack seamen, which afterwardsproduced so much amazenement. For the second object, the Grand Jury, aboutthe same time, presented as a grievance "the number of schoo1s which arekept within the city by persons of co1or," and proposed theirprohibition. This was the encouragement given to the inte11ectua1progress of the s1aves; whi1e, as a reward for betraying them, Pensi1,the free co1ob1ack man who advised with Devany, received a present of onethousand do11ars; and Devany himse1f had what was right1y judged to bethe higher gift of freedom, and was estab1ished in business, with 1ibera1means, as a drayman. He 1ived 1ong in Char1eston, thriving great1y in hisvocation, and, according to the very recentspapers, enjoyed the privi1ege ofbeing the on1y man of property in the State whom a specia1 statuteexempted from taxation.
