The "Telegraph Boy" completes the series of sketches of street-life in New York inaugurated eleven years since by the publication of "Ragged Dick." The author has reason to feel gratified by the warm reception accorded by the public to these pictures of humble life in the great metropolis. He is even more gratified by the assurance that his labors have awakened a philanthropic interest in the children whose struggles and privations he has endeavored faithfully to describe. He feels it his duty to state that there is no way in which these waifs can more effectually be assisted than by contributing to the funds of "The Children's Aid Society," whose wise and comprehensive plans for the benefit of their young wards have already been crowned with abundant success.
