"Then that's agreed," said the tinker; "I should like to do you a good turn before we part, and I hope I shall be able; at all events, if you stay with me a little while, I will teach you a trade which will serve you when all others fail." "What, to mend kettles and to grind knives?" "Exactly; and, depend upon it, if you would be sure of gaining your livelihood, you will choose a profession which will not depend upon the caprice of others, or upon patronage. Kettles, my boy, will wear out, knives will get blunt, and, therefore, for a good trade, give me `kettles to mend, knives to grind.' I've tried many trades, and there is none that suits me so well. And now that we've had our breakfast, we may just as well look out for lodgings for the night, for I suppose you would not like the heavens for your canopy, which I very often prefer. Now, put yourself to the wheel, and I'll try my old quarters." The knife-grinder walked into the village, followed by Joey, who rolled the wheel, until they stopped at a cottage, where he was immediately recognised and welcomed. Joey was ordered to put the wheel under a shed, and then followed the tinker into the cottage. The latter told his story, which created a good deal of surprise and indignation, and then complained of his head and retired to lie down, while Joey amused himself with the children. They ate and slept there that night, the people refusing to take anything for their reception. The next day the tinker was quite recovered, and having mended a kettle and ground three or four knives for his hostess, he set off again, followed by Joey, who rolled the wheel. CHAPTER TWENTY EIGHT. ON THE SCIENCE OF TINKERING AND THE ART OF WRITING DESPATCHES. They had proceeded about two miles when the tinker said--"Come, my lad, let us sit down now, and rest ourselves a bit, for it is past noon, and you must be tired with shoving that wheel along. I would have taken it from you before this, but the fact is, I'm rather stiff yet about the head and shoulders; I feel it more than I thought I should. Here's a nice spot; I like to sit down under a tree, not too well covered with leaves, like this ash; I like to see the sunshine playing here and there upon the green grass, shifting its spots as the leaves are rustled by the wind. Now, let us lie down here, and not care a fig for the world. I am a philosopher; do you know that?" "I don't exactly know what it means; a very clever, good man--is it not?" "Well, not exactly; a man may be a philosopher without being very good, or without being very clever. A philosopher is a man who never frets about anything, cares about nothing, is contented with a little, and doesn't envy any one who appears better off than himself, at least that is my school of philosophy. You stare, boy, to hear a tinker talk in this way--I perceive that; but you must know that I am a tinker by choice; and I have tried many other professions before, all of which have disgusted me."
