Read it through once
From the narrative, we infer, that Shelby was in possession of many slaves; for Mrs. Stowe speaks of a dozen black children perched on the veranda railings at one time; and it is not presumable, that all the little boys and girls in his possession, would happen to be perched on the veranda railings at the same time; and these children must have had fathers and mothers, and many of them of course, brothers and sisters, who were men and women. She also tells us, that there were various negro cabins on the place; each cabin must have contained one family of negroes at least, if not more. She speaks of a couple of negro men who went with Haley, the trader, in search of Eliza and her child.
