PREFA CE In writing this pamphlet it was the purpose of the author to bring some topics which occupy a prominent position in the standard textbooks on artillery into close connection w itli the mathematical work of a college course in trigonometry. Mr. W. H. Rayner of the College of Engineering at the University of Illinois, who is at present giving a course in Orientation for Heavy Artillery, very kindly read the manuscript. The author is under obligation to Mr. Rayner for this assistance, since the range of his own knowledge of artillery matters is limited to a careful study of some of the standard textbooks. The following books are particularly mentioned for reference: i. Alger, P. R., The Groundwork of Practical Naval Gunnery, 2nd. ed.t 1917. 2. Bishop, H. G., Elements of Modern Field Artillery, 2nd. ed., 1917. 3- Morctti, O. and Danford, R. M., Notes on Training Field Artillery Details, 6th. ed., 1918. 4- Spaulding, O. L., Jr., Notes on Field Artillery, 2nd. ed., 1917. 5- Gunnery and Explosives, War Department Document No. 39i, 1911. 6. Manual of Field Artillery, Vol. 2, War Department Document No. 614, 1917. The University Library possesses all of these books. In the text 1-4 will be referred to by the name of the author, 5 and 6 will be quoted as "Gunnery" and "Manual", respectively. Besides, the author had the privilege of reading the proof-sheets of an article by Professor / . K. Whittemore, entitled "Firing Data," which has since appeared in the American Mathematical Monthly, October, 1918. The problems 1 of page 7 and 1, 3, and 5 of pages 8, 9, and 10 are taken from Alger's excellent work; in the problems of Sections B and C emphasis has been laid on the character and on the degree of accuracy of the methods of approximation. Sections B and C are independent of Section A. r
