We are soon to have a new book from THOMAS CARLYLE--a _Memoir of the late John Sterling_, the "Archaeus" of _Blackwood_, and the author of some of the finest compositions in recent English literature. Sterling, it is known to his friends, from a devout believer became a skeptic, and then a deist, pantheist, or perhaps an atheist, and finally, having done all that he saw to do, deliberately shut himself up to die--wrote to his friends what time he should leave the world, and on the very day, as if by a mere volition, went to his place. All this is concealed or passed over very lightly by Archdeacon Hare, his biographer, and Carlyle therefore determines that the world shall have his friend's true history. Among Sterling's most intimate correspondents was Ralph Waldo Emerson, and even Carlyle cannot write his life, we suspect, without having access to the extraordinary series of letters the poet sent to his American friend--letters, we have reason to believe, that will command a greater fame for him than all his published works have won, letters that almost any man might die to be the author of. * * * * * The most noticeable event connected with literature in this country is an arrangement entered into between a New-York publisher and THOMAS H. BENTON, for the publication of the _Historical Memoirs of the Life and Times_ of that eminent person. Mr. Benton is now about sixty-eight years of age, and for half a century he has been an active participant in affairs. He was thirty years a senator from Missouri, to which state he removed some time before its admission to the Union. His name has been connected with many great measures, and very few have exercised a more powerful influence upon our institutions or policy. The increase of his strength, as well as the increase of his fame, has been gradual but regular. He has been from his youth a student. To every question which has arrested his attention he has brought all the forces of his understanding, and what he has acquired by incessant and painful labor he has to an astonishing degree retained after the occasions which made it necessary have passed. At a period much beyond the noon of other men, he was still rising. He was of the age at which Cicero achieved his highest triumphs, before he displayed the fullness and the perfection of his powers, in several of the remarkable debates which have had relation to our empire on the Pacific. With his extraordinary experience, his faithful and particular memory, and wisdom which is master of his temper, he is perhaps before every man of his time in the requisites for such an undertaking as that which has occupied his leisure for many years, and the chief portion of his time since he ceased to be a senator. His work will probably make some five large octavo volumes, and it may be believed that in fame, authority, and length of life, it will equal the immortal production of Clarendon.
