at aero-parks scattered all over France, the names of these places being withheld from mention. Here they are gathered in hundreds and given their final tests before going to the fighting line.
 Parks Back Of Lines.
 But it is on the fighting line that the real manoeuvers begin. The aero- parks for actual service are short distance in rear of the fighting forces, each park at the front being made up of four "esquadrilles." So that, as each "esquadrilles" has nine aeros, including battleplanes, cruiserpIanes, and scoutplanes. In turn, these parks back of the line are connected, so that these equipment of 26 machines in each can be rapidly brought together for a concerted attack or defense As these parks stretch from end to end of the long battleline their num- Der and aggregate of aircraft must be very large. As stated, the con- centrations of 65 fighting craft have already been carried out, and much larger concentrations are in view.
 Strange Devices Used.
 The fighting tactics have deve,oned a pnaSeS. js q strange fact that one of the most useful devices has resulted from the canture of an enemy aero This brought to light fine instrument of nrecision. made by a well-known on+i- cal firm of Berlin The instrument rcoords with exactness the moment and place when an aeroplane is ore. cisely vertical above a given point
 
 is no trusting to the eye, and when the instrument shows the vertical point-as, for example, an enemy battery below-a bomb dropped from the aeroplane is certain to hit that exact point. It is, in fact, an aerial range-finder, showing the exact mo- ment when a bomb will strike given spot.
 Another strange device used in these battle tactics is a battery of 12 small glass bottles, set in a wire rack within easy reach of the operator. The latter flies over the enemy's lines the purpose being to signal back to his own batteries how their shots are taking effect, thus giving them the exact range. The little glass bottles contain a liquid which ex- plodes five seconds after the cork is drawn, emitting little round puff of smoke, or a short trail of smoke This is aerial telegraphing. The smoke-puffs are dots: the smoke trails are dashes. Thus the pilot talks back to the far-away battery, in dots and dashes of sm oke telling the watchers that their shots are too high, or too low, or too far to the left Or right wing, and thus giving them the exact range.
 Use Of Wireless.
 Still another remarkable develop ment in the French tactics is the use of wireless, by which aeroplanes are kept in communication over a radius of 220 miles with 8 central station. The aero-Wireless is a small and deli cate set, With light atenaea above and from tip to tip of the wings, the wire automatically winding up if the aero is unmounted. These are in actual use. and besides supplying the new French machines the English and Russian machines are being similarly equipped, the demand from these threo sources being greater than two arGc manufacturing companies can produce.
 Besides the foregoing rapid deNel- 'pnlent and organization in military aVlatlon, there is a distinct branch 1 of naval aviation, with Warshlp of tonnage set aside for this l particular purpose and at one of the | ports which it is not permitted to i mention. This naval aviation looks | after the coast points, the approach 1 of hostile craft and the aerial strategy | of the sea as the army conducts the l aerial strategy on land.
