The activity of the girls who had received instruction in household economics in free schools showed progress in another direction. They formed a society under the name of the African Dorcas Association for the purpose of procuring and making garments for the destitute. The boys, too, contributed their share to this progress, taking up such trades as sail makers, tire-workers, tailors, carpenters and blacksmiths. Such reports[12] represent the condition of the free Negroes of New York before slavery was completely abolished. This change in the status of the Negroes then, and the evolving industrial system effected a change in the economic condition of the Negro throughout the city.[13] It must be remembered in this connection, however, that these Negroes experienced difficulties on account of their color either in obtaining a thorough knowledge of the trades or, after they had obtained it, in finding employment in the best shops. White and black laborers at first worked together in the same room and at the same machine. But soon prejudice developed. It was made more intense by the immigration into this country of a large number of poor Germans and Irish, who came to our shores because of the disturbed conditions of Europe. Their superior training and experience enabled them to get positions in most of the trades. Most northern men, moreover, still objected to granting Negroes economic equality. When the supply of labor exceeded the demand, the free Negroes, unable to compete with these foreigners, were driven not only from the respectable positions, but also from the menial pursuits. Measures to restrict to the whites employment in higher pursuits were proposed and where they were not actually made laws, public opinion, to that effect, accomplished practically the same result. This reversal of the position of labor, however, did not take place without a struggle, for there soon arose ill-feeling which culminated in the riots between 1830 and 1840.[14] In spite of this condition, Arthur Tappan, Gerrit Smith and William Lloyd Garrison reported to the Second American Convention for the Improvement of the Free People of Color that "by perseverance, the youth of color could succeed in procuring profitable situations.[15] To these benefactors, however, it was soon evident that Negroes had to be trained for the competition with white laborers or be doomed to follow menial employment. In accordance with this Gerrit Smith established in 1834 a school in Peterboro, for the purpose of training Negro youths under the manual labor system.[16] With such training, he believed, free Negroes would gain a livelihood, send their children to school, and gradually accumulate money. He hoped that many of them would make progress to the extent of possessing property valued at $250, which amount would enable citizens of color[17] to vote in the State of New York.
