The barber chuckled. Then a fly lit on the barber's nose and he slapped at it, and the slap missed the fly but did not miss the nose. The barber was irritated. At this moment his birdlike eye gleamed a gleam as it fell upon customers approaching: the prettiest little girl in the world, leading by the hand her baby brother, Mitchy-Mitch, coming to have Mitchy-Mitch's hair clipped, against the heat.

It was a hot day and idle, with little to feed the mind--and the barber was a mischievous man with an irritated nose. He did his worst.

Meanwhile, the brooding Penrod pursued his homeward way; no great distance, but long enough for several one-sided conflicts with malign insulters made of thin air. "You better NOT call me that!" he muttered. "You just try it, and you'll get what other people got when THEY tried it. You better not ack fresh with ME! Oh, you WILL, will you?" He delivered a vicious kick full upon the shins of an iron fence-post, which suffered little, though Penrod instantly regretted his indiscretion. "Oof!" he grunted, hopping; and went on after bestowing a look of awful hostility upon the fence-post. "I guess you'll know better next time," he said, in parting, to this antagonist. "You just let me catch you around here again and I'll----" His voice sank to inarticulate but ominous murmurings. He was in a dangerous mood.

Nearing home, however, his belligerent spirit was diverted to happier interests by the discovery that some workmen had left a caldron of tar in the cross-street, close by his father's stable.

He tested it, but found it inedible. Also, as a substitute for professional chewing-gum it was unsatisfactory, being insufficiently boiled down and too thin, though of a pleasant, lukewarm temperature. But it had an excess of one quality--it was sticky. It was the stickiest tar Penrod had ever used for any purposes whatsoever, and nothing upon which he wiped his hands served to rid them of it; neither his polka-dotted shirt waist nor his knickerbockers; neither the fence, nor even Duke, who came unthinkingly wagging out to greet him, and retired wiser.

Nevertheless, tar is tar. Much can be done with it, no matter what its condition; so Penrod lingered by the caldron, though from a neighbouring yard could be heard the voices of comrades, including that of Sam Williams. On the ground about the caldron were scattered chips and sticks and bits of wood to the number of a great multitude. Penrod mixed quantities of this refuse into the tar, and interested himself in seeing how much of it he could keep moving in slow swirls upon the ebon surface.

Other surprises were arranged for the absent workmen. The caldron was almost full, and the surface of the tar near the rim.

Penrod endeavoured to ascertain how many pebbles and brickbats, dropped in, would cause an overflow. Labouring heartily to this end, he had almost accomplished it, when he received the suggestion for an experiment on a much larger scale. Embedded at the corner of a grassplot across the street was a whitewashed stone, the size of a small watermelon and serving no purpose whatever save the questionable one of decoration. It was easily pried up with a stick; though getting it to the caldron tested the full strength of the ardent labourer. Instructed to perform such a task, he would have sincerely maintained its impossibility but now, as it was unbidden, and promised rather destructive results, he set about it with unconquerable energy, feeling certain that he would be rewarded with a mighty splash.
