A new English publication, intended specially for booksellers, and called the Intelligencer, has the startling piece of news, that Mrs. STOWE is a large slaveholder! And this is the manner thereof: "Her slaves are numerous, and, what slaves are not generally, rather respectable; more than that, they are slaves of capital, and are actually doing very good business at the present moment. They are the publishers of London. From the moment Uncle Tom's Cabin landed here, these London publishers had no rest. Directly it came out, there were a dozen of them reprinting it, each running frantically all over the trade with his own little shilling book; when they went to bed at night, when they woke in the morning, it was Uncle Tom. With Ida, Ida, Ida, rang the woods. The life of some London publishers at that time was one fever of the mad. Then there came a lull. They rested from their labors. Uncle Tom disappeared gradually from shop windows, from parlor chairs, from back kitchen corners, and in the book trade we had a little peace. Several of the publishers went down to the coast to recruit after the tremendous wear and tear of such a fearful excitement."
