Equally helpful was the work of Arabella Jones. Educated at the St. Frances Academy at Baltimore, she was well grounded in the English branches and fluent in French. She taught on the "Island," calling her school "The St. Agnes Academy."[1] Another worker of this class was Mary Wormley, once a student in the Colored Female Seminary of Philadelphia under Sarah Douglass. This lady began teaching about 1830, getting some assistance from Mr. Calvert, an Englishman.[2] The institution passed later into the hands of Thomas Lee, during the incumbency of whom the school was closed by the "Snow Riot." This was an attempt on the part of the white people to get rid of the progressive Negroes of the District of Columbia. Their excuse for such drastic action was that Benjamin Snow, a colored man running a restaurant in the city, had made unbecoming remarks about the wives of the white mechanics.[3] John F. Cook, one of the most influential educators produced in the District of Columbia, was driven out of the city by this mob. He then taught at Lancaster, Pa. [Footnote 1: _Ibid._, p. 211.] [Footnote 2: _Ibid._, p. 211.] [Footnote 3: _Special Report of the U.S. Com. of Ed._, p. 201.] While the colored schools of the District of Columbia suffered as a result of this disturbance, the Negroes then in charge of them were too ambitious, too well-educated to discontinue their work. The situation, however, was in no sense encouraging. With the exception of the churches of the Catholics and Quakers who vied with each other in maintaining a benevolent attitude toward the education of the colored people,[1] the churches of the District of Columbia, in the Sabbath schools of which Negroes once sat in the same seats with white persons, were on account of this riot closed to the darker race.[2] This expulsion however, was not an unmixed evil, for the colored people themselves thereafter established and directed a larger number of institutions of learning.[3] [Footnote 1: The Catholics admitted the colored people to their churches on equal footing with others when they were driven to the galleries of the Protestant churches. Furthermore, they continued to admit them to their parochial schools. The Sisters of Georgetown trained colored girls, and the parochial school of the Aloysius Church at one time had as many as two hundred and fifty pupils of color. Many of the first colored teachers of the District of Columbia obtained their education in these schools. See _Special Report of U.S. Com. of Ed._, 1871, p. 218 _et. seq._] [Footnote 2: _Sp. Report_, etc. 187, pp. 217, 218, 219, 220, 221.] [Footnote 3: _Ibid._, pp. 220-222.]
