Useful As a Tank?

Somebody had a nerve to invent it, all right, as if we didn't have troubles enough as it is, dodging the regimental dentist, and ducking shells, and clapping on gas masks, and all the rest. It is designed, according to one who professes to know about it, to kill the nerves of anything that gets in front of it; so we one and all move that it, instead of the tanks, be sent "over the top" and tried on the Boches. The minute they see a fully-lighted, white-painted car, with the dentist, arrayed with all his instruments of maltreatment, standing ready for action by his electric chair, those Boches will just turn around and run, and run, and run, and won't stop running till they get smack up against their own old barbed wire on the Eastern front. The crowned heads of Europe tremble before the advance of the crowned teeth of America, as you might say if you were inclined to joke about it; which we aren't.
