"You are right, Jumbo. It is lucky the storm has begun so early; if we had got far into the defile we should have been caught. Now, all we have got to do is to wait. Go back, Dick, and send up every man with fire-arms; we must at once engage those fellows in front and occupy their attention. If they once perceive their danger they will make a desperate rush down here, and it will go hard with us then. When you have sent the fighting-men up, see that the teamsters move all the waggons to the highest piece of ground you can find in the valley. Let them arrange the waggons there as closely as they will pack, and keep the animals well round them. A flood will destroy our enemy, but I am not sure that it may not destroy us too. Now hurry away, and tell the fighting-men to run up as quick as they can. When you have seen everything in readiness, join Tom, and warn him to be ready to fall back to the waggons as soon as the flood comes." Dick ran down the ravine. It was not until he issued from it that he was aware how tremendously the rain was pouring down. In the defile he had been conscious only of a slight mist, with an occasional drop of heavy rain, for very few of the rain-drops which entered the gap far above descended to the bottom, almost all striking against the sides. In the comparatively open valley, however, the rain was coming down in a perfect cataract. Dick at once sent all the fighting-men to the front, and three minutes later the report of musketry told that they were engaged with the enemy. Dick now set to work with ten of the natives to select the spot on which to place the waggons. The bottom of the valley was very flat, and the sand between the boulders showed that when the water was high the whole was covered. He, however, found a spot on the left-hand side, about midway between the two defiles, which was some feet higher than the rest. The hill-side behind at this point rose somewhat less abruptly than elsewhere, and it was probable that the rise in the bottom was formed by a slip which had taken place at some past period. Here the waggons were arranged side by side in two rows, the wheels of the three inner waggons close against the slope above them. The cattle were gathered closely round. Dick then joined Tom, whom he found in high spirits, the hunters having already told him that the flood would very soon come to their relief. The party was hotly engaged. About thirty or forty yards intervened between them and their enemy, who, crouching behind rocks, were shooting their arrows high into the air, so that they came down almost perpendicularly upon the defenders. One of these had been killed and three severely wounded by the missiles; while they themselves could only get an occasional shot at a limb exposed beyond the shelter of the boulders.
