I, with one of the others, will keep a lookout for the next two hours and, at the end of that time, will rouse you and the others." Leigh's watch had passed off quietly.

There was no movement among the guns and, from the position in which Bruno was lying, his figure would have been seen at once, had he risen to his feet.
"If the man up there stands up, you are to awaken me at once, Andre," he said.
Overcome by the excitement and the heat of the day, Leigh dropped off to sleep almost immediately.

An hour later, he was roused by being shaken by Andre.
"The man has got up, sir." The artilleryman, after stretching himself two or three times, took up something from the ground beside him, and then went some distance down the side of the hill, but still in sight of the watchers.
"He has got something on his shoulder, sir.

I think it is a shovel, and he has either a cloak or a sack on his arm." "He is evidently up to something," Leigh replied, "but what it can be, I cannot imagine." Presently the man stopped, and began to work.
"He is digging," Andre said, in surprise.
"It looks like it certainly, but what he can be digging for I have no idea." Presently the man was seen to raise a heavy weight on to his shoulders.
"It was a sack he had with him," Andre said, "and he has filled it with earth and stones." Leigh did not reply.

The mystery seemed to thicken, and he was unable to form any supposition, whatever, that would account for the man's proceedings.
