But Mug, more interested in adventure than in science, did not drop it. Pee-wee tried to pull it away but Mug rolled over on his back in the full spirit of this tug of war, and was presently so much involved with the cord that obedience to Pee-wee’s thunderous commands was out of the question. For a few moments it seemed as if Mug might be hauled up bodily and made an integral part of the aerial.

Pee-wee endeavored by lassoing maneuvers and jump-rope tactics to release the enmeshed pup, using the entire porch roof for his stage of action. He loosed the cord, imparted long wavy motions to it, jerked it, pulled it to the right, pulled it to left, but all to no avail.

At last the puppy extricated himself, and with no regard at all for his harrowing experience, immediately made a dash for the departing flat-iron handle, caught it, shook it, ran half-way across the lawn with it, shook it again, and darted around a bush with it.

The bush was not a participant in this world war. Pee-wee pulled with all his might and main, part of the bush came away, the puppy pounced upon the fleeing fragment, it dropped from the cord, and the puppy with refreshed energy caught the flat-iron handle again, bracing his forelegs for the tussle, his tail wagging frantically. Thus has every great scientist encountered hardships and obstacles.

“You get away from that now, do you hear what I tell you!” Pee-wee roared.

He might have pulled the cord away from his diminutive antagonist but that it caught in a crack between two shingles at the edge of the porch roof. The cause of science seemed to be baffled at every turn, and on the edge as well. If Mug rolled over on his back again all hope might be lost in new complications.

In desperation, Pee-wee glanced about him for something to throw at Mug by way of diverting his attention to fresh novelties. The puppy was already on his back, the cord wound around one of his forelegs. The roof was clear of all possible missiles. Pee-wee pulled out a loose shingle and hurled it down but Mug saw it not.

Then Pee-wee did something which showed his power of sacrifice. He pulled out of his pocket the sole remaining cocoanut-ball from a purchase of three—for a cent. It was heavy, and sticky, and encased in tissue paper. There was no time to take even a single bite of it.

“Here you go, Mug! Here you go, Mug!” he called.

The new temptation enabled Mug to extricate himself. He did not care for candy but he was a ready adventurer in the matter of sports. His preoccupation with the rolling cocoanut-ball gave Pee-wee the opportunity to crawl cautiously to the edge of the roof and disentangle the cord where it had caught.
