AGRICULTURAL PRIZE ESSAYS.--A well-printed pamphlet of an hundred and forty pages lies before us, containing an 'Essay on the Preparation and Use of Manures,' and on 'Farm Management,' by WILLIS GAYLORD, Esq., editor of 'The Cultivator,' one of the most widely circulated journals in the United States. The first essay is an elaborate consideration of the laws of nutrition; the preparation and distribution of animal, vegetable, and mineral manures; and the second is a well-digested compend of all the various kinds of information and directions necessary to the successful management of a farm. The useful pamphlet concludes with essays upon plans for farm-houses and out-buildings, (illustrated by several clearly-engraved wood-cuts,) by Mr. JOHN J. THOMAS, Macedon, New-York, Mr. G. D. MITCHELL, Salem, Conn., and Mr. T. M. NIVEN, Newburgh. BATTLE OF BUNKER-HILL.--The small but very comprehensive volume recently put forth by Mr. C. P. EMMONS, of Charlestown, (Mass.,) containing 'Sketches of Bunker-Hill Battle and Monument, with Illustrative Documents,' should be in the hands of every American, who desires a record of this most important battle of the Revolution. In the preliminary remarks on the opening of the struggle, and the description of the great battle itself, there is nothing included that is irrelevant, while every thing is embraced that could add to the truth or force of the picture. The illustrative documents are of very great interest. On the English side, we have extracts from General HOWE'S orderly-book, letters from Generals GAGE and BURGOYNE, and several other British officers, together with divers grumbling extracts from the English newspapers, touching the result of the 'victory.' On the American side, we have the proceedings of the Committee of Safety, the accounts sent to England and to Congress, with descriptive letters from Colonel STARK, Mr. ISAAC LOTHROP, and Rev. Dr. ELLIOT. An account of the inception, progress, and final completion of the Monument, accompanied by a sectional engraving of the structure, appropriately closes the volume.
