but life in the pit at best was a precarious affair, as the three hill-dwellers were quickly to learn. before joe could even possess himself of his kites, his astonished eyes were greeted with the spectacle of all his enemies, the fireman included, taking to their heels in wild flight. as the little girls and urchins had melted away before the simpson gang, so was melting away the simpson gang before some new and correspondingly awe-inspiring group of predatory creatures.

joe heard terrified cries of "fish gang!" "fish gang!" from those who fled, and he would have fled himself from this new danger, only he was breathless from his last encounter, and knew the impossibility of escaping whatever threatened. fred and charley felt mighty longings to run away from a danger great enough to frighten the redoubtable simpson gang and the valorous fireman, but they could not desert their comrade.

dark forms broke into the vacant lot, some surrounding the boys and others dashing after the fugitives. that the laggards were overtaken was evidenced by the cries of distress that went up, and when later the pursuers returned, they brought with them the luckless and snarling brick, still clinging fast to the bundle of kites.

joe looked curiously at this latest band of marauders. they were young men of from seventeen and eighteen to twenty-three and -four years of age, and bore the unmistakable stamp of the hoodlum class. there were vicious faces among them—faces so vicious as to make joe's flesh creep as he looked at them. a couple grasped him tightly by the arms, and fred and charley were similarly held captive.

"look here, you," said one who spoke with the authority of leader, "we 've got to inquire into this. wot 's be'n goin' on here? wot 're you up to, red-head? wot you be'n doin'?"

"ain't be'n doin' nothin'," simpson whined.

"looks like it." the leader turned up brick's face to the electric light. "who 's been paintin' you up like that?" he demanded.

brick pointed at joe, who was forthwith dragged to the front.

"wot was you scrappin' about?"

"kites—my kites," joe spoke up boldly. "that fellow tried to take them away from me. he 's got them under his arm now."

"oh, he has, has he? look here, you brick, we don't put up with stealin' in this territory. see? you never rightly owned nothin'. come, fork over the kites. last call."

the leader tightened his grasp threateningly, and simpson, weeping tears of rage, surrendered the plunder.

"wot yer got under yer arm?" the leader demanded abruptly of fred, at the same time jerking out the bundle. "more kites, eh? reg'lar kite-factory gone and got itself lost," he remarked finally, when he had appropriated charley's bundle. "now, wot i wants to know is wot we 're goin' to do to you t'ree chaps?" he continued in a judicial tone.

"what for?" joe demanded hotly. "for being robbed of our kites?"

"not at all, not at all," the leader responded politely; "but for luggin' kites round these quarters an' causin' all this unseemly disturbance. it 's disgraceful; that 's wot it is—disgraceful."

at this juncture, when the hill-dwellers were the center of attraction, brick suddenly wormed out of his jacket, squirmed away from his captors, and dashed across the lot to the slip for which he had been originally headed when overtaken by joe. two or three of the gang shot over the fence after him in noisy pursuit. there was much barking and howling of back-yard dogs and clattering of shoes over sheds and boxes. then there came a splashing of water, as though a barrel of it had been precipitated to the ground. several minutes later the pursuers returned, very sheepish and very wet from the deluge presented them by the wily brick, whose voice, high up in the air from some friendly housetop, could be heard defiantly jeering them.

this event apparently disconcerted the leader of the gang, and just as he turned to joe and fred and charley, a long and peculiar whistle came to their ears from the street—the warning signal, evidently, of a scout posted to keep a lookout. the next moment the scout himself came flying back to the main body, which was already beginning to retreat.

"cops!" he panted.

joe looked, and he saw two helmeted policemen approaching, with bright stars shining on their breasts.

"let 's get out of this," he whispered to fred and charley.

the gang had already taken to flight, and they blocked the boys' retreat in one quarter, and in another they saw the policemen advancing. so they took to their heels in the direction of brick simpson's slip, the policemen hot after them and yelling bravely for them to halt.

but young feet are nimble, and young feet when frightened become something more than nimble, and the boys were first over the fence and plunging wildly through a maze of back yards. they soon found that the policemen were discreet. evidently they had had experiences in slips, and they were satisfied to give over the chase at the first fence.

no street-lamps shed their light here, and the boys blundered along through the blackness with their hearts in their mouths. in one yard, filled with mountains of crates and fruit-boxes, they were lost for a quarter of an hour. feel and quest about as they would, they encountered nothing but endless heaps of boxes. from this wilderness they finally emerged by way of a shed roof, only to fall into another yard, cumbered with countless empty chicken-coops.

farther on they came upon the contrivance which had soaked brick simpson's pursuers with water. it was a cunning arrangement. where the slip led through a fence with a board missing, a long slat was so arranged that the ignorant wayfarer could not fail to strike against it. this slat was the spring of the trap. a light touch upon it was sufficient to disconnect a heavy stone from a barrel perched overhead and nicely balanced. the disconnecting of the stone permitted the barrel to turn over and spill its contents on the one beneath who touched the slat.

the boys examined the arrangement with keen appreciation. luckily for them, the barrel was overturned, or they too would have received a ducking, for joe, who was in advance, had blundered against the slat.

"i wonder if this is simpson's back yard?" he queried softly.

"it must be," fred concluded, "or else the back yard of some member of his gang."

charley put his hands warningly on both their arms.

"hist! what 's that?" he whispered.

they crouched down on the ground. not far away was the sound of some one moving about. then they heard a noise of falling water, as from a faucet into a bucket. this was followed by steps boldly approaching. they crouched lower, breathless with apprehension.

a dark form passed by within arm's reach and mounted on a box to the fence. it was brick himself, resetting the trap. they heard him arrange the slat and stone, then right the barrel and empty into it a couple of buckets of water. as he came down from the box to go after more water, joe sprang upon him, tripped him up, and held him to the ground.

"don't make any noise," he said. "i want you to listen to me."

"oh, it 's you, is it?" simpson replied, with such obvious relief in his voice as to make them feel relieved also. "wot d' ye want here?"

"we want to get out of here," joe said, "and the shortest way 's the best. there 's three of us, and you 're only one—"

"that 's all right, that 's all right," the gang-leader interrupted. "i 'd just as soon show you the way out as not. i ain't got nothin' 'gainst you. come on an' follow me, an' don't step to the side, an' i 'll have you out in no time."

several minutes later they dropped from the top of a high fence into a dark alley.

"follow this to the street," simpson directed; "turn to the right two blocks, turn to the right again for three, an' yer on union. tra-la-loo."

they said good-by, and as they started down the alley received the following advice:

"nex' time you bring kites along, you 'd best leave 'em to home."
