As the fear of Negro immigration increased the law of 1804 was found to be inadequate.  In 1807, therefore, the legislature enacted another measure providing that no Negro should be permitted to settle in Ohio unless he could within twenty days give a bond to the amount of $500, guaranteeing his good behavior and support.  The fine for concealing a fugitive was raised from $50 to $100, one half of which should go to the informer.  Negro evidence against the white man was prohibited.[6] This law together with that of 1830 making the Negro ineligible for service in the State militia, that of 1831 depriving persons of color of the privilege of serving upon juries, and that of 1838 prohibiting the education of colored children at the expense of the State, constituted what were known as the “Black Laws."[7]

Up to 1826, however, the Negroes of Cincinnati had not become a cause of much trouble.  Very little mention of them is made in the records of this period.  They were not wanted in this city but were tolerated as a negligible factor.  D. B. Warden, a traveler through the West in 1819, observed that the blacks of Cincinnati were “good-humoured, garrulous, and profligate, generally disinclined to laborious occupations, and prone to the performance of light and menial drudgery.”  Here the traveler was taking effect for cause.  “Some few,” said he, “exercise the humbler trades, and some appear to have formed a correct conception of the objects and value of property, and are both industrious and economical.  A large proportion of them are reputed, and perhaps correctly, to be habituated to petit larceny.”  But this had not become a grave offence, for he said that not more than one individual had been corporally punished by the courts since the settlement of the town.[8]

When, however, the South reached the conclusion that free Negroes were an evil, and Quakers and philanthropists began to direct these unfortunates to the Northwest Territory for colonization, a great commotion arose in Southern Ohio and especially in Cincinnati.[9] How rapid this movement was, may be best observed by noticing the statistics of this period.  There were 337 Negroes in Ohio in 1800; 1,890 in 1810; 4,723 in 1820; 9,586 in 1830; 17,342 in 1840; and 25,279 in 1850.[10] Now Cincinnati had 410 Negroes in 1819;[11] 690 in 1826;[12] 2,255 in 1840;[13] and 3,237 in 1850.[14]

It was during the period between 1826 and 1840 that Cincinnati had to grapple with the problem of the immigrating Negroes and the poor whites from the uplands of Virginia and Kentucky.  With some ill-informed persons the question was whether that section should be settled by white men or Negroes.  The situation became more alarming when the Southern philanthropic minority sometimes afforded a man like a master of Pittsylvania County, Virginia, who settled 70 freedmen in Lawrence County, Ohio, in one day.[15] It became unusually acute in Cincinnati because of the close social and commercial relations between that city
