This circumstance is not without significance; for it is the colonized, or reservation, Indians[8] exclusively that are to figure in these pages and, since this story is a chapter in the struggle between the North and the South, the proportion of southerners to northerners among the Indian immigrants must, in the very nature of things, have weight. The relative location of northern and southern tribes seems to have been determined with a very careful regard to the restrictions of the Missouri Compromise and the interdicted line of thirty-six degrees and thirty minutes was pretty nearly the boundary between them.[9] That it was so by accident may or may not be subject for conjecture. Fortunately for the disinterested motives of politicians but most unfortunately for the defenceless Indians, the Cherokee land obtruded itself just a little above the thirty-seventh parallel and formed a "Cherokee Strip" eagerly coveted by Kansans in later days. One objection, be it remembered, that had been offered to the original plan of removal was that, unless the slaveholding southern Indians were moved directly westward along parallel lines of latitude, northern rights under the Missouri Compromise would be encroached upon. Yet slavery was not conscientiously excluded from Kansas in the days antecedent to its organization as a territory. Within the Indian country, and it was all Indian country then, slavery was allowed, at least on sufferance, both north and south of the interdicted line. It was even encouraged by many white men who made their homes or their living there, by interlopers, licensed traders, and missionaries;[10] but it flourished as a legitimate institution only among the great tribes planted south of the line. With them it had been a familiar institution long before the time of their exile. In their native haunts they had had negro slaves as had had the whites and removal had made no difference to them in that particular. Since the beginning of the century refuge to fugitives and confusion of ownership had been occasions for frequent quarrel between them and the citizens of the Southern States. Later, when questions came up touching the status of slavery on strictly federal soil, the Indian country and the District of Columbia often found themselves listed together.[11] Moreover, after 1850, it became a matter of serious import whether or no the Fugitive Slave Law was operative within the Indian country; and, when influenced apparently by Jefferson Davis, Attorney-general Cushing gave as his opinion that it was, new controversies arose. Slaves belonging to the Indians were often enticed away by the abolitionists[12] and still more often were seized by southern men under pretense of their being fugitives.[13] In cases of the latter sort, the Indian owners had little or no redress in the federal courts of law.[14]
