Bo-bo was strictly enjoined not to let the secret escape, for the neighbors would certainly have stoned them for a couple of abominable wretches, who could think of improving upon the good meat which God had sent them. Nevertheless, strange stories got about. It was observed that Ho-ti's cottage was burnt down now more frequently than ever. Nothing but fires from this time forward. Some would break out in broad day, others in the night-time. As often as the sow farrowed, so sure was the house of Ho-ti to be in a blaze; and Ho-ti himself, which was the more remarkable, instead of chastising his son, seemed to grow more indulgent to him than ever. At length they were watched, the terrible mystery discovered, and father and son summoned to take their trial at Pekin, than an inconsiderable assize town. Evidence was given, the obnoxious food itself produced in court, and verdict about to be pronounced, when the foreman of the jury begged that some of the burnt pig, of which the culprits stood accused, might be handed into the box. He handled it, and they all handled it, and burning their fingers, as Bo-bo and his father had done before them, and nature prompting to each of them the same remedy, against the face of all the facts, and the clearest charge which judge had ever given,--to the surprise of the whole court, townsfolk, strangers, reporters, and all present--without leaving the box, or any manner of consultation whatever, they brought in a simultaneous verdict of Not Guilty. [Illustration: YE FAMILY REJOICETH.] The judge, who was a shrewd fellow, winked at the manifest iniquity of the decision; and, when the court was dismissed, went privily, and bought up all the pigs that could be had for love or money. In a few days his Lordship's town house was observed to be on fire. The thing took wing, and now there was nothing to be seen but fires in every direction. Fuel and pigs grew enormously dear all over the district. The insurance offices one and all shut up shop. People built slighter and slighter every day, until it was feared that the very science of architecture would in no long time be lost to the world. Thus this custom of firing houses continued, till in process of time, says my manuscript, a sage arose, like our Locke, who made a discovery, that the flesh of swine, or indeed of any other animal, might be cooked (_burnt_, as they call it) without the necessity of consuming a whole house to dress it. Then first began the rude form of a gridiron. Roasting by the string, or spit, came in a century or two later, I forget in whose dynasty. By such slow degrees, concludes the manuscript, do the most useful, and seemingly the most obvious arts, make their way among mankind. [Illustration: YE MYSTERY IS SOLVED.]
