"See how that horse carries on, Bert," said Mr. Miller.

And, sure enough, the big brute was prancing about with ears bent back and teeth showing in a most threatening fashion.

"They daren't harness that horse until he is in his place beside the pole, Bert. See, now, they're going to put the harness on him."

And as he spoke another stable hand came up, deftly threw the heavy harness over the horse's back, and set to work to buckle it with a speed that showed it was a job he did not care to dally over. No sooner was it accomplished than the other horses were hastily put in their places, the black wheeler in the meantime tramping upon the barn floor in a seeming frenzy of impatience, although his head was tightly held.

"Now, then, 'all aboard' as quick as you can," shouted Jack Davis, swinging himself into his seat. Mr. Miller handed up Bert and followed himself, the inside passengers scrambled hurriedly in, and then with a sharp whinny the black wheeler, his head being released, started off, almost pulling the whole load himself.

"Black Rory does not seem to get over his bad habits, Jack," remarked Mr. Miller.

"No," replied Jack; "quite the other way. He's getting worse, if anything; but he's too good a horse to chuck over. There's not a better wheeler on the route than Rory, once he settles down to his work."

After going a couple of miles, during which Rory behaved about as badly as a wheeler could, he did settle down quietly to his work and all went smoothly. They were among the hills now, and the steep ascents and descents, sharp turns, and many bridges over the gullies made it necessary for Davis to drive with the utmost care. At length they reached the summit of the long slope, and began the descent into the valley.

"I'd just as soon I hadn't any doubts about this brake," said Davis to Mr. Miller, as he put his foot hard down upon it.

"Oh, it'll hold all right enough, Jack," replied Mr. Miller, reassuringly.
