GAS AND FLAME
MAJOR S. J. M. AULD, M.C.
Lieut. W. G. Thayer, of the Gas Defense Division, U. S. Army,is the artist of the drawing here reproduced which was designedfor the purpose of bringing home the necessity of care in all thatpertains to the use and manufacture of the gas mask.
In order to impress upon the soldier in training the need of careand speed in adjusting the mask in case of gas attack, the posterwas printed with this wording:
KEEP YOUR HEAD; HOLD YOUR BREATH,—
BE QUICK!!
AND THIS WON’T HAPPEN TO YOU
That the workers engaged in the manufacture of gas masksmight realize the importance of care and flawlessness in their work,the same poster was placed in the factories with a legend reading:

PUBLISHER’S NOTE
Need for the education of vast numbers ofmen in various branches of Gas Service andthose in camps on the position of Gas Warfareat the front, has made imperative the publicationof this book, as has also the need of educatingthe public, owing to the many misleadingnewspaper reports, sometimes merely misinformative,sometimes distinctly mischievous, appearingfrom time to time.
Major Auld, chemist and teacher before thewar, and as he modestly styled it, “amateursoldier,” volunteered for service at the frontas a “Territorial,” at the very outset of theconflict.
Some months after the first gas attack, hewas taken into the Gas Service, owing to histraining and ability as a chemist, and later becameChief Gas Officer to Sir Julian Byng’sArmy. He was awarded the Military Crossafter the Battle of the Somme, and was woundedin an expedition into No Man’s Land to observethe effect of a British Gas attack. He has thereforebeen in touch with gas warfare from thebeginning and knows all phases.
