=Gas Cannot be Abolished.= As to the abandonment of poison gas, it must be remembered that no powerful weapon of war has ever been abandoned once it proved its power unless a more powerful weapon was discovered. Poisonous gas in the World War proved to be one of the most powerful of all weapons of war. For that reason alone it will never be abandoned. It cannot be stopped by agreement, because if you can stop the use of any one powerful weapon of war by agreement you can stop all war by agreement. To prepare to use it only in case it is used against you is on the same plane as an order that was once upon a time issued to troops in the Philippine Islands. That order stated in substance that no officer or soldier should shoot a savage Moro, even were he approaching the said officer or soldier with drawn kriss (sword), unless actually first struck by such savage. Every officer preferred, if necessary, to face a court-martial for disobedience of such an order rather than allow a savage Moro with a drawn kriss to get anywhere _near_, let alone wait until actually struck. Let the world know that we propose to use gas against all troops that may be engaged against us, and that we propose to use it to the fullest extent of our ability. We believe that such a proposition will do more to head off war than all the peace propaganda since time began. It has been said that we should not use gas against those not equipped with gas. Then why did we use repeating rifles and machine guns against Negritos and Moros armed only with bows and arrows or poor muskets and knives. Let us apply the same common sense to the use of gas that we apply to all other weapons of war. =Effect on World War Tactics.= A very brief study of the effects of chemical warfare materials on the strategy of the World War will indicate its future. It began with clouds of chlorine let loose from heavy cylinders buried under the firing trench. These took a long time to install and then a wait, sometimes long, sometimes brief, for a favorable wind, but even at that these cloud gas attacks created a new method of fighting and forced new methods of protection. Gas at once added a tremendous burden to supply in the field, to manufacture, and to transportation, and in a short time even made some decided changes in the tactics of the battle field itself.
