'Do you hear?' said Pluizer,—'science and mankind.'

'The man of science,' the doctor went on, 'stands far above all other men. But he must make all the smaller feelings which are common to the vulgar give way to the one grand idea of science. Will you be such a man? Is that your vocation, my boy?'

Johannes hesitated; he did not know justly what a vocation might be—any more than the cockchafer.

'I want to find the book of which Wistik spoke,' said he.

The doctor looked surprised and asked, 'Wistik?'

Pluizer hastened to reply. 'He will, doctor; I know he really will. He desires to seek the highest wisdom and to understand the true nature of tilings.'

Johannes nodded, 'Yes!' So far as he understood the matter, that was what he meant.

'Very well; but then you must be strong, Johannes, and not timid and soft-hearted. Then I can help you. But remember: all or nothing.'

And with trembling fingers Johannes helped to tighten the relaxed cords round the rabbit's little paws.
