Among the students attending this Institute in 1841 were James E. Burr and George Thompson. These young men, together with a villager, Alanson Work, arranged with two slaves to convey them from bondage in Missouri. The abductors found themselves surrounded by a crowd of angry Missourians, and were speedily committed to jail in Palmyra. To insure the conviction of the prisoners three indictments were brought against them, one charging them with "stealing slaves, another with attempting to steal them, and the other with intending to make the attempt."[487] Conviction was a foregone conclusion. Work and his companions were pronounced guilty and sentenced to twelve years' imprisonment. These men were not required, however, to serve out their terms. Mr. Work was pardoned after three and a half years on the unjust condition that he return with his wife and children to the State of Connecticut, his former residence. Mr. Burr was released at the end of a little more than four years and six months, and Mr. Thompson after nearly five years' imprisonment. The anti-slavery character of Mission Institute at length brought down upon it the wrath of the Missourians. One winter night a party from Marion County crossed the Mississippi River on the ice, stealthily marched to the Institute, and set it on fire.[488] [487] Quoted by Wilson, _Rise and Fall of the Slave Power in America_, Vol. II, p. 71.

In southern Indiana operations similar to those of the students of the Mission Institute were carried on by a supposedly inoffensive pedler of notions, Joseph Sider. With his large convenient wagon Sider traversed some of the border counties of Kentucky, supplying goods to his customers; one of his boxes was reserved for disguises for negroes that wished to cast off the garments of slavery. Sider's method involved the use of his vehicle for long trips to the Ohio River, where the passengers were conveyed by boat to a place of safety, and told to remain concealed until the wagon and team could be transported by ferry the following morning. So simple a plan did not excite suspicion, and served to carry fugitives rapidly forward to some line of underground traffic.[489] [489] E.
