Sue, Mary Watson, Sadie West, Helen Newton and some others raced about, playing tag and jumping rope.

"Oh, I know what we can do!" suddenly cried Helen, when they were all tired from having romped about playing tag.

"What?" asked Sue.

"Let's go down to the end of the yard where the men are digging, and see how big the hole is," suggested Helen.

"Oh, teacher said we mustn't!" exclaimed Sadie.

"Well, we won't go very close," went on Helen. "She just told us to be careful not to fall in. But if we don't go too close we can't fall in."

This seemed a safe way of looking at it, and the girls were curious to see what the workmen had done at the far end of the school yard. The laborers had been digging for some days, fixing water pipes, and had made a deep trench, so deep that when a man stood down in it only his head showed above.

Just now none of the men was near the hole, all having gone away to get other tools, and as the boys were busy playing at the other end of the yard, or watching Charlie's auto, the girls could explore the digging by themselves.

"It's nothing but a hole!" said Sue, in some disappointment, as they approached as near as they dared and looked in.

"I'd like to go down in it!" exclaimed Helen, who was rather daring.
