monster! "he seems dejected, and I have never seen him smile," says Mr. Halliday. This boy--and a good many others who like the streets and the free air better than the black-hole of a tenement--should go to sea. The sea is an honorable trade, (it _used_ to be a profession,) and the merchants of New York could not do a wiser or a better thing than in providing a school-ship where such lads could be taught the rudiments of seamanship and navigation, or, in default of that, sending them as apprentices in their vessels. We have two complaints to enter against Mr. Halliday: first, that he has given his book a title which will deter most sensible people from opening it; and, second, that in his valuable report on the tenement-houses, he does not give the names of those enterprising personages who make thirty-five per cent, at the expense, not only of their poor tenants, but of every tax-payer in New York. _The New American Cyclopaedia: a Popular Dictionary of General Knowledge._ Edited by GEORGE RIPLEY and CHARLES A. DANA. Vol. VI. Cough--Education. New York: D. Appleton & Co. 8vo. pp. 772. More than one-third of the task assumed by the editors of this work is now completed; and the best testimony in its favor is, that, although it has been freely criticized, sometimes with closeness and severity, and sometimes with studied harshness and evident malice, its reputation has risen among candid and competent readers with the appearance of each volume. Faults, negative and positive, may undoubtedly be discovered in it; but the same is true, in a greater or less degree, of every other production of human labor; and the eyes neither of malice nor of hypercriticism have been able to find any sufficient reason why this Cyclopaedia should not be accepted as the beat popular dictionary of general knowledge in the English language. As the work advances, the comprehensiveness of its plan, the honesty of its purpose, and the truly catholic and liberal spirit which animates it, become more and more apparent; and the names of the authors of the articles (a list of which is to be published, we believe, with the last volume) sufficiently show the determination of the editors to secure the cooperation of the first talent in the country. Among the contributors to the present volume are the Rev. Dr. Bellows, Edmund Blunt, Dion Bourcicault, Professor Dana of Yale College, Edward Everett, Professor Felton of Cambridge, Parke Godwin, Richard Hildreth, George S. Hillard, William Henry Hurlbut, and Professors Lowell and Parsons of Cambridge.
