So correct are these Tables, that since their first issue in 1827 no error has been discovered. Tanning. A New and Complete Treatise on the Art of Tanning, Teeth of Wheels. £2 10 Camus (M.)

The Progress made in Naval Architecture and in Artillery necessitates a modification of the Principles heretofore observed in Coast Defence. CHAPTER I.-Railroad Communication with different points on the sea-shore preferable to fortifying places of but secondary importance, causing a scattering of Forces. CHAP. II.-Exposed Masonry not capable of withstanding the effects of Modern Artillery; Bombardments of Forts Sumter, Morgan, Jackson, St. Phillip, and Pulaski. CHAP. III.-Earth, especially Sand-works, properly constructed, a better Protection against Modern Artillery than permanent Fortifications built on the old plan; Bombardment of Island No. 10, Vicksburg, Battery Wagner, Fort Fisher, Fort Powell. CHAP. IV. Guns mounted en barbette, even when protected by properly built Traverses, may be silenced by a concentrated fire from Ships; Description of Fort Powell and Batteries on Choctaw Bluff; General Remarks on the Construction of Shore Batteries. CHAP. V.-No Fort now built can keep out a large Fleet, unless the Channel is obstructed; Attack on, and Passage of Forts Jackson and St. Phillip on the Mississippi; Passing of the Batteries at Vicksburg; Passing of the Batteries at Island No. 10 by the Federal Gunboats Carondelet and Pittsburg; Passing of Port Hudson; Confederate Gunboats running the gauntlet of Federal Batteries below Tiptonville; Confederate Ram Arkansas passes the Federal Fleet above Vicksburg; Blockade Runners. CHAP. VI. A merely partial Obstruction of the Channel not sufficient to enable Forts to keep out a large Fleet; Passage of Fort Morgan by the Federal Fleet under Rear-Admiral D. G. Farragut, and Naval Engagement in the Lower Bay of Mobile; General Orders and detailed Report of Rear-Admiral D. G. Farragut; Description of Confederate Ram Tenessee; Loss of United States Steamer Philippi and Monitor Tecumesh. CHAP. VII.-No Fleet can force a Passage if kept under the Fire of heavy Batteries by properly constructed Obstructions; First Attack on Fort Sumter; Admiral Farragut's Opinion of the Obstructions of Spanish River and Choctow Pass in the Upper Bay of Mobile. CHAP. VIII.-Views of Rear-Admiral David D. Porter on Coast Defence. PART II. On Obstructions. CHAP. IX.-Importance of Obstructions; to determine the Nature of an Obstruction which should satisfy all demands; Obstructions to be prepared in time of Peace; Division of Obstructions; Position of Obstructions in relation to shore-batteries; Strength required; Cost-price. CHAP. X.-On Sunken Obstructions: Dams, Sunken Vessels, Rocks; On Obstructions formed by Piles, Chevaux-de-Frise, Sawyers. CHAP. XI.-On Floating Obstructions; Booms, Chains, Rafts, and Rope Obstructions; Obstructions formed by Combination of Rafts, Ropes, and Torpedoes: Captain Piron's System. CHAP. XII.-Torpedoes: Experience demands Simplicity of Construction; Torpedoes are divided into Stationary Torpedoes, Torpedoes used in offensive operations against the enemy; according to methods of firing; by contact self-exploding Torpedoes; Torpedoes fired from Shore; Methods of firing Torpedoes, by the Match, Acids, Percussion, Friction, Electricity.

'Any book written like the volume before us, by competent hands, and treating of the scientific conduct of the campaigns, must be of great value to military men. The book contains so much valuable matter as to be worth a place in all military libraries."-Times. "It is impossible to read the pages of Von Scheliha's handsome volume without being convinced that it constitutes an admirable contribution to the literature of military engineering. The arrangement of the work and the system of treatment adopted by the editor are excellent; so excellent that we have failed to find room for improvement. These propositions he has derived from the results of experience acquired by the contending armies. He attempts no proof of the accuracy of his propositions other than that sup plied by the official reports laid before Congress, nor is other proof required. To reject our author's propositions, is to reject the knowledge acquired by experience. Taken as a whole the work is excellent."-Engineer. |
