Mr. Rawmarsh was not the only intelligent man who took an interest in Godwin. In a house which the boy sometimes visited with a school-fellow, lodged a notable couple named Gunnery the husband about seventy, the wife five years older; they lived on a pension from a railway company. Mr. Gunnery was a dabbler in many sciences, but had a special enthusiasm for geology. Two cabinets of stones and fossils gave evidence of his zealous travels about the British isles; he had even written a little hand-book of petrology which was for sale at certain booksellers' in Twybridge, and probably nowhere else. To him, about this time, Godwin began to resort, always sure of a welcome; and in the little uncarpeted room where Mr. Gunnery pursued his investigations many a fateful lesson was given and received. The teacher understood the intelligence he had to deal with, and was delighted to convey, by the mode of suggested inference, sundry results of knowledge which it perhaps would not have been prudent to declare in plain, popular words. Their intercourse was not invariably placid. The geologist had an irritable temper, and in certain states of the atmosphere his rheumatic twinges made it advisable to shun argument with him. Godwin, moreover, was distinguished by an instability of mood peculiarly trying to an old man's testy humour. Of a sudden, to Mr Gunnery's surprise and annoyance, he would lose all interest in this or that science. Thus, one day the lad declared himself unable to name two stones set before him, felspar and quartz, and when his instructor broke into angry impatience he turned sullenly away, exclaiming that he was tired of geology. 'Tired of geology?' cried Mr. Gunnery, with flaming eyes. 'Then _I_ am tired of _you_, Master Peak! Be off, and don't come again till I send for you!' Godwin retired without a word. On the second day he was summoned back again, but his resentment of the dismissal rankled in him for a long time; injury to his pride was the wrong he found it hardest to forgive.
