GAS TRAINING IS
 IMPORTANTFEATURE
ONE OF THE FIRST THINGS IS TO TEACH RECRUITS HOW TO
 PROTECT HIMSELF.
Two Methods Used by Germans, oneI to Let Gas Escape When Winds Are Favorable, and Other to Shoot Gas in Shells.

May 25.-CCorrespondence of the As socated Press -One of the most es- sential parts of recruits training is that winch teaches him to protect himself against gas attack. It has| been proved that practically completeI security can be obtained against this latest weapon, but that such serulty is dependent upon previous trainins.
 This special training is provided for every British recruit by the special gas schools" establisher at conyen tent points behind the front Every recruit must complete course of in struction here before he is allowed toI take his place in the front line.
 "The objects of our traiinng," said the British officer who showed theI Associated Press correspondent thru one of these schools, are to familiar | ize the soldier with the various anti-| gas apparatus, and to fix firmly in his| mind the two chief axioms to be|
 learned in the use of gas--the GrstI
 being that carelessness may mean sudden death, the second that al rroper procedure gives absolute ifo-I
 munity from any ill-effect.'
 The gases employed by the enemy are of two kinds, lethal and non lethal The first class will produce death if breather in sufficient qUan-
 ties. The second class include lach- rymatory of tear gas, and number of similar gases to produce merely temporary effects. The gases are em- ployed in two ways, by release from sylinders when favorable winds are blowing, or by enclosing them in
 shells fired from guns and trench
 mortars
 At the gas school the men are all taught to protect themselves against i both forms. Two appliances are used
 in the British army The "boX res | IlRrator,' which is the newest and most important of these, consists of 8 flexible mask that fits over the face. 1 This mask is fitted with glass win dOws for the eyes a clip to cover the nostrils to prevent the wearer breath |
 mouthpiece fitted with valve. The mouthpiece admits of free eXhalation, 1 but forces inhalation to take place through d tin box, Conected to the mOuthpiece by flexible tube, and containing the chemicals that absorb
 the gas, allowing only pure air to pass into tAe lungs The whole devise is Icarried by every soldier in satchel slung over the chest
 The men are trainde to put the ap- pliance into use in a minimum time. As soon as they gre expert in the de-
 tails of fitting the mask they are put
 through various drills, carrying the
 apparatus At a word of command
 the ystop instantly whatever they are
 doing and fit the mask into posi-
 ton. These drills are continued un-
 til a hole company can protect itself
 in few seconds
 They are then exercised in carry
 ing out more complicated drills, in
 cluding prolonged double quick
 marching, with the apparatus in its
 place. until they are fully accustomed
 to working the inconvenience caused thereby.
 Each man is given a respirator that
 fits him perfectly and which thence
 forth becomes his personal property I The fit is tested by placing each man
 for several minutes in a chamber
 heavily charged with gas. If he eX-
 hibits any symptoms of discomfort at
 the end of the test, he must be fittco
 with a new mask. In order to inspire
 confidence. he is later put through the most exacting tests in rooms fill l ed with the most deadly gases, from | which he suffers no ill effects what
 ever.
 later step in the gas school is
 raining in methods Of clearing ga out of dugouts and methods of pre- venting gas getting into duaonts The gas, being heavier than air, collects in such places if allowed to, and the methods of construotng impervious doors, impervious blanket curtains and similar devices, are shown. The recruit is shown the iprindlples of ventilation, whereby gas can be blown blown out of dugouts by the use 0i fans or by lighting fires at favorable points near the entrance. Actual ex- periments along these lines are carried out in the school and are studied by the men.
 The most essential thing to be done in case of gas attack, the instructor tells his pupils, is to warn everybody within reach The men are shown how to construct gas gongs out of any ma terial at hand, such as lengths of rail way iron or artillery cartridge cases and where to place such alarms SC s that they may best be heard The ust ' lOf the "Strombe Horn, a special form s of motor horn worked by cylinder oI 4 compressed air is also explained.
