L. M. NULTON. Navy being to destroy an enemy, this ant line. ( )ur first work, in Second ling force, using The Landing b ' orce icins as a text Ixicik. In this we learn le hanilling of the crew of a ship for , ' or field artillery. The study is )esides the mechanical maiucuvring first aid to the voun led. camping and camp hygiene, patrols, ceremonies, and the method of con- ducting small arms target practice, . fter this we study ship and gun drills. Under this comes the organization of gun crews, drills for varin-us types of guns, emergency drills, the inspection, marking and stowage of ammunition, torpedo drills and the methods of conducting physical exercises. Later in the year a general text-book on ordnance is studied. In this we take up guns and m;-unts and the process of manufacture, ex- p losives of all kinds, manufacture, use and stowage: armor, its manufacture, di-p. )-,iti(in and the method of securing it to a ship: magazines, location and care: ammunition, hoists, and a general description of mine fields. In b ' irst Class year the confidential pamphlets on service torpedoes are studied. These give us an accurate descri])tion of all ])arts and their functions, the care of torpedoes and mines, and the use of each. We then take up .Mger ' s ICIastic Strength of Guns, covering the calculations of strains to which giuis are sub- jected in firing and the strength of material necessary to .stand these strains, h ' .xterior I ' .allis- tics is the ne.xt subject, covering the motion of projectiles, the computation and use of ballistic tables, the derivation of formuke for the correction of errors of fire and the penetration of pro- jectiles. The last work is in gunnery instructions, giving us the methods of training crews, spot- ting shells at target [jractice and the scheme of fire control. .Ml during the course practical exer- cises with service ;;).(; mV supplement the book wi irk. Included in this practical work are small arms target practice and fencing. Spotting and fire cunlrol are taught by our actually using guns and targets, on a reduced scale, faithfully reproducing target practice conditions.

The subject, known familiarly to ii as Xaw is first taken np in the second term of Second Class year. White ' s Astronomy is studied with the idea of havin;;- us yet a general idea of the solar system, the causes of seasons, cause of tides, eclipso, phases of the moon and other iihen imena. Toward the end of the term Xavi-alion in its true sense is started, our text hook hem- -Muir, with r.owditch ' s Tahles, Nautical Alm.anacs, and Azimuth les as auxiliaries. ' I ' lie instrununts used in na igati n — compass, log and lea l, se.xlant. artificial horiz(jn. ]ielorus, of chart construction, the instruments used i ' n chart work, and the meaning of chart terms, are studied an.! used practically. h:iemeiitary methods of fixing the position of a vessel hoth at sea and near land are studied S(.i as to give us some knowledge of navigation with which to start on the practical work of first class cruise. ( )n the ciaiise. each l- ' irst Classman is re(|uired each day to take sights, and therehy fix the pisition (if the ship at noon, to determine the course and distance made gocd since noon of the da ' before, the direction and strength of the currents encountered, and the course and distance to the point of destinatii.Mi. The various methods of fixing the ship ' s [. ' osition are learned jiractically so that in l- ' irst Class ear the mathematical exi)lanations are much more tangible than they w..uld otherwise he. The three weekly recitations are on theoretical work, in- tical works are gi ' en. in general, covering the work of the wx-ek. h ' rom time to time chart wcn ' k is given, courses and distances being laid down a;id taken ot f as in practice at sea. Xearh all of the examinations are thoroughly practical. In the second term the Theory of Com|)ass Devia- tions is studied and the various methods of compensation with Iheir mathematical explanations taken up. ' J ' he course also includes the elements of surveying. At the end of llu- ye.ar e.ach h ' irst Classman constructs a complete chart of a ])orlion of the Severn River from data obtained (huing the s|)riug drill i)eri(jds by surveying [)arties of miilshipmen. 29
