He stopped abruptly.

"What's the matter?"

"Nothing," said John.

Prudence, the kill-joy, had whispered in his ear. He visualized Prudence as a thin, pale-faced female with down-drawn lips and mild, warning stare who murmured thinly, "Is it wise?" Before her whisper primitive emotions fled, abashed. The caveman in John fled back into the dim past whence he had come. Most certainly, felt the Twentieth-Century John, it would not be wise. Very clearly Pat had shown him, that night in London, that all that she could give him was friendship, and to gratify the urge of some distant ancestor who ought to have been ashamed of himself he had been proposing to shatter the delicate crystal of this friendship into fragments. He shivered at the narrowness of escape.

He had heard stories. In stories girls drew their breath in sharply and said "Oh, why must you spoil everything like this?" He decided not to spoil everything. Walking warily, he reached the little gate that led to the boathouse steps and opened it with something of a flourish.

"Be careful," he said.

"What of?" said Pat. It seemed to John that she spoke a trifle flatly.

"These steps are rather tricky."

"Oh?" said Pat.
