His mother, twice a widow, moved back to "Woolsthorpe," a big name for a very small estate. Isaac was made the man of the house. The ambition of his mother was that he should become a farmer and stock-raiser.
It seems that the boy entered upon his farm duties with an alacrity that was not to last. His heart was not in the work, but the desire to please his mother spurred him forward.
On one occasion, being sent with a load of produce to Grantham, he stopped to visit his old school, and during his call struck a bargain with one of the boys for a copy of Descartes' Geometry. The purchase exhausted his finances, so that he was unable to buy the articles his mother had sent him for, but when he got home he explained that one might get along without such luxuries as clothing, but a good Geometry was a family necessity. About this time he made a water-clock, and also that sundial which can be seen today, carved into the stone on the corner of the house. He still continued his making of kites which had been begun at Grantham; and gave the superstitious neighbors a thrill by flying kites at night with lighted lanterns made from paper, attached to the tails. He made water-wheels and windmills, and once constructed a miniature mill that he ran by placing a mouse in a treadmill inside.
In the meantime the cows got into the corn, and the weeds in the garden improved each shining hour. The fond mother was now sorely disappointed in her boy, and made remarks to the effect that if she had looked after his bringing up instead of entrusting him to an indulgent grandmother, affairs at this time would not be in their present state. Parents are apt to be fussy: they can not wait.
Matters reached a climax when the sheep that Isaac had been sent to watch, overran the garden and demolished everything but the purslane and ragweed, while all the time the young man was under the hedge working out mathematical problems from his Descartes.
At this stage the mother called in her brother, the Reverend Mr. Ayscough, and he advised that a boy who was so bound to study should be allowed to study.
And the good man offered to pay the wages of a man to take Isaac's place on the farm.
So, greatly to the surprise and pleasure of Mr. Stokes of Grantham, Isaac one fine day returned with his books, just as if he had only been gone a day instead of a year.
At the home of the apothecary the lad was thrice welcome. He had endeared himself to the women of the household especially. He did not play with other boys—their games and sports were absolutely outside of his orbit. He was silent and so self-contained that he won from his schoolfellows the sobriquet of "Old Coldfeet." Nothing surprised him; he never lost his temper; he laughed so seldom that the incident was noted and told to the neighbors; his attitude was one of abstraction, and when he spoke it was like a judge charging a jury with soda-water.
All his spare time was given up to whittling, pounding, sawing, and making mathematical calculations.
