They turned down a side lane, and Bart heard no more, but this was enough to prove to him that the Doctor’s would be no bed of roses if everything did not turn out to be as good as was expected.

He reported this to the Doctor, who only smiled, and hurried on his preparations.

Money was easily forthcoming as soon as it was known that the government favoured the undertaking; and at last, with plenty of rough mining implements, blasting powder, and stores of all kinds, the Doctor’s expedition started at daybreak one morning, in ample time to keep the appointment with the Beaver.

“I say, Master Bart,” said Joses, as he sat upon his strong horse side by side with Bart, watching their train go slowly by, “I think we can laugh at the Apachés now, my lad; while, when the Sharp-Toothed Beaver joins us with his dark-skinned fighting men, we can give the rascals such a hunting as shall send ’em north amongst the Yankees with fleas in their ears.”

“It’s grand!” cried Bart, rousing himself up, for he had been feeling rather low-spirited at parting from Maude, and it had made him worse to see the poor girl’s misery when she had clung to her father and said the last good-byes. Still there was the fact that the governor and his lady were excellent people, and the poor girl would soon brighten up.

And there sat Bart, on his eager little horse, Black Boy, which kept on champing its bit and snorting and pawing the ground, shaking its head, and longing, after weeks of abstinence, to be once more off and away on a long-stretching gallop across the plains.

There were men mounted on horses, men on mules, greasers driving cattle or the baggage mules, some in charge of the waggons, and all well-armed, eager and excited, as they filed by, a crowd of swarthy, poncho-wearing idlers watching them with an aspect of good-humoured contempt and pity on their faces, as if saying to themselves, “Poor fools! what a lot of labour and trouble they are going through to get silver and become rich, while we can be so much more happy and comfortable in our idleness and dirt and rags!”

A couple of miles outside the town the mob of idlers to the last man had dropped off, and, bright and excited, the Doctor rode up in the cheery morning sunshine.

“I’m going to ride forward, Bart,” he cried, “so as to lead the van and show the line of march. You keep about the middle, and mind there’s no straggling off to right or left. You, Joses, take the rear, and stand no tricks from stragglers. Every man is to keep to his place and do his duty. Strict discipline is to be the order of the day, and unless we keep up our rigid training we shall be in no condition to encounter the Indians when they come.”

“What are these coming after us?” cried Bart, looking back at a cloud of dust.
