The McLoughlin Brothers, a publishing firm located in Springfield, Massachusetts, specialized in reprinting various texts for children. They reprinted Uncle Tom's Cabin at least several times in the first two decades of the 20th century, sometimes in their "Young Folks Standard Library" series, sometimes with New York as the publication place, and with at least two different covers and frontispieces (see below).
Although uncredited, the person who adapted Stowe's text did a careful job both shortening it by two-thirds and revising or eliminating passages that must (half a century after Stowe's novel was a family favorite) have now seemed inappropriate for children. For example, in Chapter 17 Simon Legree tells Cassy he's had a "terrible" night instead of a "hell of" one; Legree spurns his mother, but never physically abuses her; and the story Cassy tells in Chapter 16 replaces her white lover with a white father who dies suddenly, before he can free her. Other changes are harder to account for, such as making George Harris a religious teacher rather than a political leader when he ends up in Liberia.
All the editions I've seen are very cheaply and carelessly printed, with numerous typos -- including the misnumbering of chapters. Most errors have been silently emended in this electronic text.
