"Oh! burying bones, I suppose," said Tom; "He's always at it. I believe he'd dig a hole in an iron floor if he was chained up on it. Hallo, Pete! stop that! You're making too much dust. Do you hear me, sir? Very well! you'd—a—bet—" When Tom got as far as "bet," pronounced in an awful voice, Pete knew that a stick was forthcoming. He accordingly paused in his digging, his little black nose covered with yellow earth, and his eyes fixed mournfully on the half-finished hole. "Let us go and dig up some of his bones and show them to him," said Tom; "it always makes him feel so ashamed! I know where they are; he has his favorite places, and I've often seen him toiling up and down from one to the other, as important as the man that goes round with the panorama and jaws at the people."
"What an expression!" said Gem, with an air of superiority; "you boys are so common!"
"And you girls are so soft!" said Tom. "I'd rather be a boy than a girl, any day. Come, now!"
But Gem was not inclined to argue this point, so they carried out their bone-hunting project, much to the discomfiture of Pete Trone, Esq., who followed behind as if fascinated, watched the disinterment of each relic with mortified interest, and, when the last was brought into view, drooped his head and tail, and sought refuge in the corn-field where he relieved his feelings by burrowing wildly in twenty different places.
"There come the B. B.'s!" exclaimed Gem, interrupting Tom in a search for artichokes; "eight of them, as sure as you live!"
"What an expression," said Tom, imitating his sister's voice; "you girls are so common!" But the approach of the visitors made a truce a matter of necessity, and soon the project of the tree-house engrossed the entire attention. Boards were brought from the little tool-house, saws were in demand, and Gem was deputed to confiscate all the hammers and nails in the house for the use of the builders; the work went bravely on, and by noon the walls of the fortification were up, and the roof well advanced towards completion. A ladder brought from the barn, took the workmen half-way up the trunk; but the old tree was lofty, and a long space intervened between the end of the ladder and the lowest branches, which must of necessity be ascended in that squirming manner peculiar to boys, wherein they delight to bark their shins, tear their trousers, and blister their hands in the pursuit of glory. Gem, of course, could not hope to emulate the B. B.'s in this mode of progression towards the fortification, but she brought nails and carried boards with great energy. When there was no call for her services, she watched with intense interest the B. B. who happened to be squirming up. If there was no B. B. squirming up, there was sure to be one squirming down, for a principal part of the time seemed to be devoted to journeys below and aloft, besides elaborate contrivances for slinging boards and tools to the climbers' backs; indeed, to a looker-on, this seemed to be the chief interest of the fortification.
At last it was done, all but the floor; Tom said it did not matter about that, as the boys could easily stand on the branches. Word was given to ascend, and, one by one, all the B. B.'s squirmed up the tree and took their places inside; nothing was to be seen but their feet, huddled together on the branches. It took ten minutes for all the band to assemble on high, but in less than two, down they squirmed again. "What is the matter?" said Gem in astonishment; she had not expected to see the B. B.'s for hours, absorbed as they would be in their leafy abode.
"We're going to take up the dogs," said Tom, who came first; "we're going to sling 'em up in a basket. It will be such fun, and they'll like it first-rate."
"Oh, don't, Tom!" exclaimed Gem; "Turk is too big, Grip will be sure to fall out, and it will make Pete Trone seasick."
But no attention was paid to her remonstrances, and the B. B.'s inspired to new exertions, made numerous journeys up and down, rigging a pulley and making various preparations for the aerial voyage. When all was ready there was a discussion as to which dog should go. Turk was too big, no basket would hold him; and Grip, Tom said, had "no common sense," and would not appreciate the situation. Pete Trone was evidently the man for the place, and he jumped gayly into the basket at Tom's command, without any suspicion of danger; and when he found himself hanging in mid-air, he did not flinch, but settled down resolutely on his haunches, looking over the side with one eye as much as to say, "Who's afraid?"
