The other letter gives an account of the Alton riot and the killing of Rev. Elijah P. Lovejoy. This is one of the few contemporary accounts we have of that shocking event. Although he was not an eye-witness of the riot, the facts as stated are substantially correct, and the comments give us a view of the opinions of the writer at the age of twenty-four, touching a subject in which he was destined to play an important part. The letter is subjoined: BELLEVILLE, SUNDAY, Nov. 12, 1837. DEAR FATHER: Since my last to you there has been a mob to put down Abolitionism, in Alton, thirty-five miles northwest of this place, in which two persons were killed and six or seven badly wounded. The immediate cause of the riot was the attempt by a Mr. Lovejoy to establish at Alton a religious newspaper in which the principles of slavery were sometimes discussed. Mr. Lovejoy was a Presbyterian minister and formerly edited a newspaper in St. Louis, but having published articles in his paper in relation to slavery which were offensive to the people of St. Louis, a mob collected, broke open his office, destroyed his press and type and scattered it through the streets. Immediately after this transaction, which was about a year since, Mr. Lovejoy left St. Louis, and removed to Alton, where he attempted to re-establish his press, but he had not been there long before a mob assembled there also, broke into his office and destroyed his press. In a short time Mr. Lovejoy ordered another press which, soon after its arrival in Alton, was taken from the warehouse (where it was deposited), by a mob, and in like manner destroyed. Again he ordered still another press, which arrived in Alton on the night of the 7th inst., and was safely deposited in a large stone warehouse four or five storeys high.
