7. Thou shalt not kill--TIME. 8. Thou shalt not adulterate thy mess tin by using it as a shaving mug. 9. Thou shalt not bear false witness against thy comrades but preserve a strict neutrality on his outgoings and his incomings. 10. Thou shalt not covet thy sergeant's post, nor the corporal's nor the staff major's, but do thy duty and by dint of perseverance rise to the high position of major general. SOME THINGS THAT WE OUGHT AND OUGHT NOT TO SEND Candies, cigarettes--and ordinary, plain cigarettes are good enough, so long as you send plenty. If he chews, send him chewing. Cigarettes are an absolute necessity because they are the only things soothing to the nerves when under heavy shell fire. Powdered milk in small quantities, or Horlick's Milk Tablets, are always welcome. Pure jam; don't ever make a mistake in this and send plum and apple, because if he ever gets back alive, he will surely take your life for making such a terrible mistake--different fruit preserves they long for. Never send corned beef. This would be even a worse crime than the plum and apple jam. A pair of sox, home-made and pure wool, you ought to send once a week, because you must remember the Red Cross takes care only of the wounded men and not the fighters in the trenches; the government and home folks must look after the fighter in the field. Three-finger mittens knitted up to the elbow, with the first finger absolutely bare, are very welcome. Scarfs are quite unnecessary. Tommy usually gives these to the French lassies. Different insect powders Tommy likes to get, because he can't buy these out there. There is no doubt about it that, although we get used to the "cooties," yet sometimes they outnumber us and it is necessary to put a gas attack over on them. Strong powders are the only thing. Candles, matches, and if possible small alcoholic burners are very essential things. Of course, if you send him a burner it would be necessary for you to keep sending him alcohol, because this can't be bought in France. Nor can we get sugar out there. Any of these things with a nice long "letter" will delight Tommy or Sammy or Poilou. Transcriber's note: Minor typographical errors in the original text have been corrected.
