 be trained to act together almost as one unit And just as the first con- tingent of American infantry will de- vote itself largely through the fall and winter to training other units as they arrive, so the first contingent of ar tillery will train the batteries, regi- ments and bfigades which will be thrown into France before the spring campaign of 1918 is likely to begin.
 While it is not known here what an nouncements may have been made from Washington the arrival of a large section of American field artillery in France has been kept a carefully guarded secret so far as Europe is concerned. The announcement is per mitted now, only after the officers and men have progressed far in their in- tensive training under general super vision of Frances most expert artil- lerists.
 There are no longer any French of ficers or poilus actually serving at the guns, the crews having been Ameri- caniZed throughout. At the observa- tion posts and in the schools of in struction French officers sit now only III all duNlSOTy CdpdClly.
 Through various reports received from trained observers, attaches and other confidential sources during the last three years, the American artil- lery officers of the regular army have been enabled to keep in fairly close touch with all the gunnery develop ment in the world war-sufficiently close, in any event, to change many o1 their older practices within the last twelve months, while at the same time keeping them abreast the more mod 1 ern theories of the artillery schools What the American artillery has now and never had before, is plenty of shells.
 It Is easily conceived what this : means to the enthusiastic officers ano men, whose batteries are expendine within two or three weeks ten times the number of shells formerly allotted to them for an entire year.
 Modern artillery training is a maze of technical details, labyrinth o1 mathematical problems, a never-end ing series of intricate puzzles. ir which such elusive and subtle subjects as orientation, triangulation. deflection drift, elevation, calculation, meteorol- ogy and a dozen other branches ot optics and geometry and the genera application of the concentrated power. Of destruction are involved
 The French have also supplied tn, Americans with six inch HowitZers-s gun Of great power and accuracy which corresponds to the noted German 5.9 probably the most effective weapon fl the entire German gun list
 The Americans have been quick t6 master the details of the French weape ons and are handling them now as ii they had been friends of many years standing. Under the watchful super. Vlslon of a splendid old French ma jor who speaks English as if il were nl own tongue. they have taken down ant reassembled the two types of guns witt which they have been training. so tha- the most minute detail of construction ana the particular use of each part nc matter how small, has become thor oughly known. The mastery of artil- lery, as whole, however, is a matte, or months rather than weeks, and ther, still remains much for even the frs American artillery contingent to learn
 Ine work of cooperation with bal looms and airplanes has only recently been started. The airplane service has attracted many of the brightest young oificers in the artillery, who are prac- eicing now to qualify as observers.
