'Her?' I cried. 'Who?' For the man bewildered me.

'Why, the wheel, miss! You understand! This is business, you bet! And you're jest the right woman!'

He motioned me on. Urged by a sort of spell, I remounted my machine and rode out of the village. He followed, on the box-seat of his cab. Then, when we had left the world well behind, and stood among the sun-smitten boles of the pine-trees, he opened the door mysteriously, and produced from the vehicle a very odd-looking bicycle.

It was clumsy to look at. It differed immensely, in many particulars, from any machine I had yet seen or ridden.

The strenuous American fondled it for a moment with his hand, as if it were a pet child. Then he mounted nimbly. Pride shone in his eye. I saw in a second he was a fond inventor.

He rode a few yards on. Next he turned to me eagerly. 'This ma-chine,' he said, in an impressive voice, 'is pro-pelled by an eccentric.' Like all his countrymen, he laid most stress on unaccented syllables.

'Oh, I knew you were an eccentric,' I said, 'the moment I set eyes upon you.'

He surveyed me gravely. 'You misunderstand me, miss,' he corrected. 'When I say an eccentric, I mean, a crank.'

'They are much the same thing,' I answered, briskly. 'Though I confess I would hardly have applied so rude a word as crank to you.'

He looked me over suspiciously, as if I were trying to make game of him, but my face was sphinx-like. So he brought the machine a yard or two nearer, and explained its construction to me. He was quite right: it was driven by a crank. It had no chain, but was moved by a pedal, working narrowly up and down, and attached to a rigid bar, which impelled the wheels by means of an eccentric.
