"That's a fine healthy English way of looking ac things, but if you'd lived in this country as long as I have you'd know that when you spot such a troop in the distance the best thing you can do is to clear out--unless, that is, you have any particular wish for trouble."

"But why on earth should you suppose they're not peaceable folk--a hunting-party, perhaps?"

"Supposing's neither here nor there. Hunters don't ride in a line, without hounds. My belief is that they're brigands, and we shan't have much to say to them with one revolver between the two of us."

"They may be soldiers."

"That's only another name for brigands here. The only difference is that a soldier is a brigand in office, and a brigand is a soldier out of office. And, by Jeremy! they've got a prisoner. There's a man trotting a-foot beside one of the horses; ten to one he's tied to the stirrup. Take a look, Mr. Pentelow."

"You're right; and I can see now they've got rifles slung to their backs. They're making a bee-line this way. What's their game, I wonder?"

"Shouldn't be surprised if they've paid a visit to the mines, to begin with."

"I think I've got it," said Will, the recollection of what Antonio de Mello had said flashing across his mind. "There's a revolution brewing: these fellows are either Government troops or rebels. We had better get back and tell the Chief."

"I said so five minutes ago, if you recollect, Mr. Pentelow. In this country there are always plots against the Government, whether it's good, bad, or indifferent--and it's mostly bad. Revolution is always on the simmer, you may say, and every few years it boils over. It's the curse of the country. Any big job like this railway of ours is like sitting on a powder-barrel: any moment you may be blown sky high, in a manner of speaking. If Government don't interfere with you, then Revolutionists will; and I'll lay ten to one those horsemen are one or the other, beating up recruits. They haven't seen us yet or they'd be coming faster, so we had better slip in among the trees and gallop for railhead. We can at least put the Chief on his guard."

They led the ponies into the wood, then mounted and set off at full speed. Mr. Jackson looked grave when he heard their report, to which Will added the information given him by Antonio de Mello in the morning. He at once whistled up the other European members of his staff from the scattered points at which they were engaged. When they came up he explained the position to them.
