"'During this time two large bodies of troops had passed through and each time they were heavily shelled with dire results.
"'On the sixth night of our assignment, utterly disgusted, I, being in charge, had decided to chuck up the whole business and report back to Old Pepper that we had made a mess out of the investigation. My partner pleaded with me to stick it out a couple of days more, and after he gave me a vivid description of what Old Pepper would hand out to us, I decided to stick it out for six months, if necessary.
"'To celebrate this decision, my side-kicker offered to blow to several rounds of drinks. Now, this fellow had never, during my acquaintance with him, offered to spend a ha'penny, so I quickly accepted his offer and we went to the nearest estaminet.
"'Sitting around a long table, drinking French beer and smoking cigarettes, was a crowd of soldiers, laughing, joking, arguing and telling stories.
"'We sat down at the end of the table, and in low tones, tried to work impossible theories as to how the spy, if there was one, and by this time we were getting doubtful, could get the information back to the German batteries.
"'Right across from us were two soldiers arguing about farming. Suddenly my side-kicker pinched me on the knee and whispered:
"'"Listen to what those two fellows across the table from us are saying. It sounds good."
"'I listened for about a minute and then paid no further attention. At that time farming in no way interested me. I wanted to catch that spy, and started devising impossible theories as to the ways and means of doing so. At last I gave up in disgust. My partner was still attentively listening to the two across the table from us. Another poke in the knee from my partner, and I was all attention.
"'One of the fellows across the way was talking.
"'"Well, I don't see why this French blighter should change horses in his plow every afternoon. I've watched him for several days. Now, in the morning he uses two greys, and then about two in the afternoon he either hooks up two blacks or a grey and a black. French ways may be different, but this frog-eater is very partial to the colors of his team. Figure it out for yourself. He starts work with the two greys about six o'clock in the morning; works the two beggars up till noon. That's six hours straight. Then he sticks them in the stable, lays off for two hours, and in the afternoon about two o'clock the new relay of animals come on and work up till four. Now, anybody with any brains in their nappers knows that that is no way to keep horses in condition, working one team over six hours and the other team only two hours. I know because we have been farmers in our family back in Blighty for generations."
