And he was not mistaken, the old man was delighted with the cakes, and at once broke and ate one, while he began to tell Peter one of the stories for which he was famous, and which he knew Peter loved to hear. But Peter suddenly remembered his promise not to stay out late, and finally became so uneasy that he told the old man he must not wait to hear the end of the story, and, hastily bidding him farewell, started towards home.

His path lay beside the dyke, and along its grassy banks grew beautiful wild flowers of many varieties, so numerous and attractive that Peter decided to pick a bunch of them to carry home to his mother, who was so much of an invalid that she was seldom out of the house. So he picked a few here and a few there—blue and yellow and pink, until he had a handful of those varieties of which he knew his mother was most fond, and as he walked on, to keep himself from feeling lonesome, he hummed a gay little song.

Presently, he stopped, and neither sang nor smiled, as he looked at a slender thread of water trickling through the grass. Where did it come from? Surely not from the canal, and there was nowhere else for it to come from unless it came from the dyke itself.

The thought was enough to make even a child turn pale and tremble. Only the dykes stood between the boundless sea and the safety of little Holland. He looked again, and to his imagination, the stream seemed greater already. What could he do? Night was coming on, the road was a solitary one. There was only the barest chance of anyone passing that way whom he might hail, or of whom he could ask advice.

Then came a quick recollection of his promise to his father, and he started homeward again, but a force as mighty as a giant's grasp, made him turn back again to watch that trickling stream of water.

He was near one of the great oaken sluices, and bounding up beside it he carefully examined the dyke. There, as small as his finger, was a hole—strange and unaccountable happening,—and through that little hole was flowing the stream of water at his feet.

Like lightning the flash of intuition came to Peter, if that hole were not stopped up instantly, the force of the flow through it would rapidly increase from the pounding of that mighty sea behind it. In a night the flood would break through the dyke and perhaps destroy all the homes in Holland.

What could he do? No stone would fit the hole, no amount of earth packed into the crevice could resist the pressure of the water. Peter was desperate. Forgotten now were his bunch of flowers which fell unheeded from his hand. He strained his eyes in a vain search for travellers on that lonely road, vainly he shouted out for help until his throat was hoarse. What could he do? It was no common instinct that came in that lightning flash to Peter. Climbing again up the steep bank, from stone to stone, he thrust his finger in the hole and, oh, joy, it fitted! It stopped the trickling water for the moment, but, oh, what would happen when he took it out?

Ah, it was as clear as daylight, what to do. He would not take it out until someone should come to relieve him. Forgetful of what this idea might bring to him, if carried out, he chuckled with a boyish delight in this real adventure.

"Ha, ha!" he said to himself. "The water can't come down now. Haarlem shall not be drowned while I am here to keep the flood back."
