“That will be pretty nearly as safe for them as walking into a lion’s mouth,” objected Frank. “The country below there must be alive with government troops and they are sure to encounter them.”

“There is nothing we can do till we get back to La Merced, that is certain,” rejoined the philosophical Harry. “It’s no use crossing bridges till we come to them. If the army marches to-morrow we should be at home by the morning of the day after at the latest.”

With this reflection the boys turned in and slept like tops for two hours or so. Their awakening was a startling one. The whole air seemed filled with shouts and yells and there was a scattering sound of shots coming from somewhere in the interior of the jungle.

“It’s a night attack!” shouted Frank, springing up and hastily throwing on his clothes. “Come on, Harry!”

Both boys rushed out of their tent just as General Ruiz came to the door.

“We have been attacked,” he said, “it looks like treachery somewhere. I don’t know how many of them there are; but, so far, we have them in hand.”

“You mean we have beaten them off?” asked Frank.

Ruiz shook his head.

“I am too old a soldier to believe that Rogero would attack me with a handful,” he said. “No, boys, this attack was made by an advance guard to draw our fire and ascertain just how large a force we really have. The real attack will come in a few minutes.”

He was buckling on his sword as he spoke and thrusting his navy revolver into a holster. This completed he held out his hand.
