"I'd give a good deal to see the fellows," sighed Jimmy, as, his breakfast finished, he stood up and stretched himself. He was feeling decidedly better, and very wide awake. "Wonder if we dare go up or down the lines a little way."

"You're a sarge. You can travel around, I guess, with no come-back. I wouldn't want to risk it, though. This front-line business doesn't carry many privileges."

"Even so, we can't stick to the fire step all the time. We have to sleep in the dugouts, and when it's quiet we'll be allowed to hang around in them. It's at night that we'll have to do most of our work, I suppose."

"Yes, I presume so. After we get used to this trench system we'll know better how to manage our affairs," was Bob's sage opinion. "We'll have to ask these fellows who are here to help us all about what to do."

Breakfast over and quiet still continuing, the men were ordered to the dugouts for rest.

Earlier in the great war, the heroes of Ypres, Mons, the Marne, and of other memorable battles, found trench life almost unendurable. Since then trench conditions have changed for the better. To-day there are plenty of dugouts, trench platforms, and many other conveniences which help to make the men on trench duty vastly more comfortable than of old.

After seeing that his men were made as comfortable as possible, Jimmy accompanied Bob to one of the dugouts, and flung themselves wearily down on the narrow canvas cots provided for their rest. Just before entering the dugout, however, both had gone a little way up and down the line in search of their bunkies. Failing to find them, and sadly in need of rest, they had agreed to postpone the search until later.

How long they slept neither knew. Both were awakened by a thunderous roar that threatened to split their eardrums.

Instantly springing from their cots, they made a dash for the dugout's opening, along with the rest of the men it contained. All knew what had happened. The enemy had at last been heard from.

Among the first to gain the trench, Jimmy saw that a portion of the parapet on his right had been demolished. It had fallen into the trench completely blocking it. His heart stood still as he saw at the edge of that heap of tossed-up earth an olive-drab arm moving feebly.
