Besides, it would rain or snow, and it rarely snowed in a decent Christian manner by Christmas.  It snowed slush, as Newton expressed it.  A certain kind of snow-slush makes nice hard snowballs, it is true, just like stones, but when there is no other boy to fight, it is no good.  Overholt had once offered to have a game of snow-balling with his son on a Saturday afternoon in winter; and the invitation was accepted with alacrity.  But it was never extended again.  The boy was a perfect terror at that form of diversion.  Yet so distressed was Overholt at the prospect of a sad Christmas for his son that he even thought of voluntarily giving up his thin body to the torment again on the 25th of December, if that would amuse Newton and make it seem less dull for him.  Good-will towards men, and even towards children, could go no further than that, even at Christmas time.  At least Overholt could think of no greater sacrifice that might serve.

For what are toys to a boy of thirteen?  He wants a gun and something to kill, or he wants a boat in which he can really sail, or a live pony with a real head, a real tail, and four real legs, one at each corner.  That had been Newton’s definition of the desired animal when he was six years old, and some one had given him a wooden one on rockers with the legs painted on each side.  Girls of thirteen can still play with dolls, and John Henry had read that, far away in ancient times, girls dedicated their dolls, with all the dolls’ clothes, to Artemis on the eve of their wedding-day.  But no self-respecting boy of thirteen cares a straw for anything that is not real, except an imaginary pain that will keep him away from school without cutting down his rations; and in the invention and presentation of such fictitious suffering he beats all the doll-makers in Germany and all the playwrights and actors in the world.  You must have noticed that the pain is always as far from the stomach as is compatible with probability.  Toothache is a grand thing, for nobody can blame a healthy boy for eating then, if he can only bear the pain.  And he can, and does, bear it nobly, though with awful faces.  The little beast knows that all toothaches do not make your cheek swell.  Then there is earache; that is a splendid invention; it goes through your head like a red-hot corkscrew with a powerful brakeman at the other end, turning it steadily—­between meals.  Only certain kinds of things really serve to make him stop.  Ice-cream is one, and it takes a great deal of it.  It is well known that ice will cool a red-hot corkscrew.

But this is a digression, for no boy ever has any pain at Christmas; it is only afterwards that it comes on; usually about ten days.

After an hour Overholt came to the conclusion that he had better take Pandora’s box out to the cottage and sit on it there, since nothing suggested itself to him, in spite of his immense good-will to accept any suggestion which the spirit of coming Christmas might be kind enough to offer; and if he could do nothing else, he could at least work at his machine, and try to devise some means of constructing the tangent-balance, with the materials he had left, and perhaps, by the time he was thoroughly grimy and the workshop smelt like the Biblical bottomless pit, something would occur to him for Newton.
