The rioters sought, especially, for John F. Cook, who, however, had seasonably taken from the stable the horse of his friend, Mr. Hayward, the Commissioner of the Land Office, an anti-slavery man, and fled precipitately from the city. They marched to his school-house, destroyed all the books and furniture, and partially destroyed the building. Mrs. Smothers, who owned both the school-house and the dwelling adjoining the lots, was sick in her house at the time, but an alderman, Mr. Edward Dyer, with great courage and nobleness of spirit, stood between the house and the mob for her protection, declaring that he would defend her house from molestation with all the means he could command. They left the house unharmed, and it is still standing on the premises. Mr. Cook went to Columbia, Pennsylvania, opened a school there, and did not venture back to his home till the autumn of 1836. At the time the riot broke out, General Jackson was absent in Virginia. He returned in the midst of the tumult, and immediately issuing orders in his bold, uncompromising manner to the authorities to see the laws respected at all events, the violence was promptly subdued. It was, nevertheless, a very dark time for the Colored people. The timid class did not for a year or two dare to send their children to school, and the whole mass of the Colored people dwelt in fear day and night. In August, 1836, Mr. Cook returned from Pennsylvania and reopened his school, which under him had, in 1834, received the name of UNION SEMINARY. During his year's absence he was in charge of a free Colored public school in Columbia, Lancaster County, Pennsylvania, which he surrendered to the care of Benjamin M. McCoy when he came back to his home, Mr. McCoy going there to fill out his engagement.
