His course took him so near the back of the car that he had to turn out, a step or so, to avoid collision with it. He accompanied this turning-out maneuver by another which was less ostentatious, but more purposeful. Timing his steps, so as to pass by the rear of the car just as the Master was busy helping his wife to descend, the youth thrust an arm over the side of the tonneau, with the speed of a striking snake. His hand closed on the handle of a traveling bag, among the heap of luggage. Never slackening his pace, the negro gave a fierce yank at his plunder, to hoist it over the closed door. In that tourist-ridden city, bag-stealing offered much profit. In the rare chance of detection when he was at work, the boy had only to plead over-zeal in trying to earn an honest dime by helping lift the luggage to the sidewalk. It was a pretty bit of theft; and it betokened long and careful practice. Thus,--from the thief's standpoint,--it was almost a pity the brilliant effort was wasted. For wasted it was. This young negro prided himself on his powers of speed and of silence, in plying his trade. And, today, though he proceeded to excel in the first of these qualities, he disgraced himself most woefully as regarded the second. For he jerked his hand out of the tonneau far faster than he had thrust it in. As he did so, he woke the echoes with the most blood-curdling screech his leathern lungs could compass. As his dusky fingers had closed on the bag, something viselike and relentless had fastened upon those same expert fingers; breaking two of them, and rending the flesh of the lower hand. Lad, in rising to his feet, after his pleasant nap, at the slowing of the car, had been aware of that predatory hand; as it groped for the bag. Now, from puppyhood, Lad had been taught to regard everything in the car as under his own careful guardianship. Hence, he lunged forward and sank his terrible white teeth deep into the groping fingers. By main force the youth tore free. With a second screech, he reeled back from the unseen peril which had assailed him. But Lad would not have it so. There was a harsh-breathed growl, from down in the tonneau; and, on the instant, a tawny giant shape came catapulting over the top of the shut door and hurled itself upon the staggering negro. The Master, turning at sound of the yell, was just in time to see the attack. The collie,--supposedly ninety miles away, and peacefully guarding the Place,--was hurtling through the air and crashing against the chest of a gray-faced and pop-eyed young negro. To earth went the two; in a cloud of dust; a second before the Master's sharp call brought Lad reluctantly away from his prey, and just as a policeman and a score of idlers came running up.
