Among the valuable educational works of the past month, we notice WOODBURY'S _Shorter Course with the German Language_, presenting the main features of the author's larger work on a reduced scale. (Published by Leavitt and Allen.)--KIDDLE'S _Manual of Astronomy_, an excellent practical treatise on the elementary principles of the science, with copious Exercises on the Use of the Globes (published by Newman and Ivison),--and RUSSELL'S _University Speaker_, containing an admirable selection of pieces for declamation and recitation. (published by J. Munroe and Co.) _Summer Gleanings_, is the title of a book for the season by Rev. JOHN TODD, consisting of sketches and incidents of a pastor's vacation, adventures of forest life, legends of American history, and tales of domestic experience. A right pleasant book it is, and "good for the use of edifying" withal. Lively description, touching pathos, playful humor, and useful reflection, are combined in its pages in a manner to stimulate and reward attention. Every where it displays a keen and vigorous mind, a genuine love of rural scenes, a habit of acute observation, and an irrepressible taste for gayety and good-humor, which the author wisely deems compatible with the prevailing religious tone of his work.

This period, including the whole of Madison's administration, with a portion of that of Jefferson and of Monroe, is one of the most eventful in American history, and sustains a close relation to the existing politics of the country. No one can expect an absolute impartiality in the historian of such a recent epoch. Mr. Hildreth's narrative is undoubtedly colored, to a certain degree, by his political convictions and preferences, which, as we have seen, in the last volume, are in favor of the old Federal party; but, he may justly challenge the merit of diligent research in the collection of facts, and acute judgment in the comparison and sifting of testimony, and a prevailing fairness in the description of events. He never suffers the feelings of a partisan to prejudice the thoroughness of his investigations; but always remains clear, calm, philosophical, vigilant, and imperturbable. His condensation of the debates in Congress, on several leading points of dispute, exhibits the peculiarities of the respective debaters in a lucid manner, and will prove of great value for political reference. His notices of Josiah Quincy, John Quincy Adams, Madison, Monroe, and Henry Clay, are among the topics on which there will be wide differences of opinion; but they can not
