It was a serious and sad accident, and, for a time, cast a gloom over the camp. But it was one of those seemingly unavoidable things for which no one in particular was to blame. A court martial was held, and the officer in charge of the work exonerated.

Nor was the commander of the battery, the firing of the guns of which loosened the soft earth, held responsible. He had nothing to do with the trenches, and it was not his fault.

The accident had its effect, though, in causing greater care to be taken in making trenches after that, and bag or basket work was used, to better bind the earth together. It was a soft and sandy soil, without much body to it, and it shifted more easily than would earth that had a clay mixture.

The accident was also used to good advantage in causing a deeper study of trench work, and the manner of making the trenches and laying them out. Many of the recruits had a deep-seated aversion to grubbing in the ground, digging trenches, but it was part of the drill work and had to be done. The lads likened it to sewer work, and no one liked it.

After the accident one of the French officers, who was an instructor in camp, gave a series of lectures on trench warfare, and at the conclusion there was not only a noticeable improvement in the trenching, but there was more enthusiasm about it.

“A trench may save our lives when we get to France,” was the way Jerry expressed it. “I’m going to learn all I can about them.”

“Same here!” echoed Ned.

What with athletic work, learning the different marching and fighting formations, doing the necessary police work, studying the mechanism of rifles and machine guns, learning how to signal, digging trenches, throwing hand grenades and dozens of other things, Ned, Bob and Jerry were kept busy from morning until night. So with the other recruits.

Of course there was a certain time set aside for play and amusement, and each young soldier was told to play as hard as he worked. This was so he might come back to his tasks refreshed, and with the desire to give them the very best that was in him.

The motor boys soon realized that the making of a soldier was a task that was growing in complication. There were many new ways of fighting, and defending oneself, and all these had to be mastered.
