In the eastern section of the city, about 1840, Alexander Cornish had a school several years in his own house on D Street, south, between Third and Fourth, east, with an average of forty scholars. He was succeeded, about 1846, by Richard Stokes, who was a native of Chester County, Pa. His school, averaging one hundred and fifty scholars, was kept in the Israel Bethel Church, near the Capitol, and was continued for about six years. In 1840, there was a school opened by Margaret Hill in Georgetown, near Miss English's seminary. She taught a very good school for several years. ALEXANDER HAYS'S SCHOOL was started on Ninth Street, west, near New York Avenue. Mr. Hays was born in 1802, and belonged originally to the Fowler family in Maryland. When a boy he served for a time at the Washington Navy Yard, in the family of Captain Dove, of the navy, the father of Dr. Dove, of Washington, and it was in that family that he learned to read. Michael Tabbs had a school at that time at the Navy Yard, which he taught in the afternoons _under a large tree_, which stood near the old Masonic Hall. The Colored children used to meet him there in large numbers daily, and while attending this singular school, Hays was at the same time taught by Mrs. Dove, with her children. This was half a century ago. In 1826, Hays went to live in the family of R. S. Coxe, the eminent Washington lawyer, who soon purchased him, paying Fowler $300 for him. Mr. Coxe did this at the express solicitation of Hays, and seventeen years after he gave him his freedom--in 1843. While living with Mr. Coxe he had married Matilda Davis, the daughter of John Davis, who served as steward many years in the family of Mr. Seaton, of the "National Intelligencer." The wedding was at Mr. Seaton's residence, and Mr. Coxe and family were present on the occasion. In 1836, he bought the house and lot which they still own and occupy, and in 1842, the year before he was free, Hays made his last payment, and the place was conveyed to his wife. She was a free woman, and had opened a school in the house in 1841. Hays had many privileges while with Mr. Coxe, and with the proceeds of his wife's school they paid the purchase-money ($550) and interest in seven years. Mr. Hays was taught reading, writing, and arithmetic by Mr. Coxe, his wife, and daughters, while a slave in their family. When the Colored people were driven from the churches, in the years of the mobs, Mrs. Coxe organized a large Colored Sabbath-school in her own parlor, and maintained it for a long period, with the cooperation of Mr. Coxe and the daughters. Mr. Hays was a member of this school. He also attended day schools, when his work would allow of it. This was the education with which, in 1845, he ventured to take his wife's school in charge. He is a man of good-sense, and his school flourished. He put up an addition to his house, in order to make room for his increasing school, which was continued down to 1857--sixteen years from its opening.
