As soon as it was dark and the meal eaten, the tents were struck, the baggage all rolled up and packed on the animals, and the fireworks divided. When everything was in readiness they went together and made a breach in the breast-work wide enough for the mules to pass. At nine o'clock Maria was seated in the carrying-chair, and strapped on to her husband's back; then four brands were taken from the fire and the party started. When within fifty yards of the lower end of the ravine José went forward, and, returning in a few minutes, reported that no savages were on guard. A fire was burning outside the mouth of the ravine where he had seen them on the evening before, and from the reflection on the rock he believed that another fire was alight inside. His report caused a general feeling of relief, for their great fear had been that the natives might have made off before their arrival.
When they stepped out from the water Dias set Maria down. "You understand, Maria," he said: "the moment I call, you are to start up the river."
"I understand," she said. "I have my knife, and if you do not rejoin me I shall know how to use it."
"We shall rejoin you, Maria," Dias said confidently. "I believe that at the first volley of fireworks they will be off. They must be more than human if they are not scared, as they never can have heard of such things before."
Keeping close to the rock wall, they went along in single file until within forty or fifty yards of the fire; then, going down on their hands and knees, they crawled up a slight rise, from the top of which they could see a hundred or more natives gathered round a fire. One was addressing the others, who were seated listening attentively. Laying the guns down to be ready for instant action, and keeping themselves concealed in the herbage, Harry took his bundle of squibs from his pocket. They were but lightly tied together; slipping off the string he applied the ends to the brand. There was a sudden roar of fire, and waving them once round his head he hurled them into the midst of the assembly. There was a yell of astonishment as the missiles flew hither and thither, exploding with loud reports. The last had not exploded when Bertie's handful flew among them; then came the parcel from Dias, and at the same moment Harry poured a barrel of buck-shot among them, followed by a volley of crackers, while almost simultaneously Harry threw his squibs and Bertie fired a volley of buck-shot. For a moment the savages were paralysed, then many of them threw themselves on their faces in terror of these fiery demons, while others started in headlong flight.
"Send them off as quick as you can!" Harry shouted, as he discharged his second barrel into the flying natives. Bertie followed suit, and then both paused to reload while Dias and José hurled their remaining fireworks. By this time the last of the natives had leapt up and fled. José's musket and the three rifles cracked out, and then the little party rose to their feet and joined in a wild "Hip, hip, hurrah!"
"You can come up, Maria; they have all gone!" Dias cried out; and Maria joined them a minute later. More than a score of natives lay dead or badly wounded round their fire.
"What are we to do with the wounded?" Bertie asked.
"We can only leave them where they are," Harry said. "Some of the savages may have wandered away, or not have come down from the hills, and will return here unaware of what has happened, or one or two of the boldest may venture back again to look after their comrades. At any rate, we can do nothing for them."
"It would be better to shoot them, señor," Dias said.
