woman. Out of this union came a desirable mulatto girl who married a
surgeon of Nantes then stationed at Pittsburgh. His family was considered
one of the most respectable of the city. The Negro referred to was doing a
creditable business and his wife took it upon herself to welcome
foreigners, especially the French, who came that way. Along the Ohio also
there were several cases of women of color living with unmarried white men;
but this was looked upon by the Negroes as detestable as was evidenced by
the fact that, if black women had a quarrel with a mulatto woman, the
former would reproach the latter for being of ignoble blood.[23]

These tendencies, however, could not assure the Negro that the Northwest
Territory was to be an asylum for freedom when in 1763 it passed into the
hands of the British, the promoters of the slave trade, and later to the
independent colonies, two of which had no desire to exterminate slavery.
Furthermore, when the Ordinance of 1787 with its famous sixth article
against slavery was proclaimed, it was soon discovered that this document
was not necessarily emancipatory. As the right to hold slaves was
guaranteed to those who owned them prior to the passage of the Ordinance
of 1787, it was to be expected that those attached to that institution
would not indifferently see it pass away. Various petitions, therefore,
were sent to the territorial legislature and to Congress praying that the
sixth article of the Ordinance of 1787 be abrogated.[24] No formal action
to this effect was taken, but the practice of slavery was continued even
at the winking of the government. Some slaves came from the Canadians who,
in accordance with the slave trade laws of the British Empire, were
supplied with bondsmen. It was the Canadians themselves who provided by
act of parliament in 1793 for prohibiting the importation of slaves and
for gradual emancipation. When it seemed later that the cause of freedom
would eventually triumph the proslavery element undertook to perpetuate
slavery through a system of indentured servant labor.
