When he reached the turn in the defile he crawled forward among the boulders until he reached a spot where he could obtain a clear view of the barrier; it was to the full as formidable as it had been described by the scouts. It would have needed an active man to scale the rocks without any opposition from above, while on the top a dense body of natives were clustered, numbering at least fifty, and probably a considerable portion of their force was concealed from view. Mr Harvey sent back one of the natives to tell Dick to come on and join him; after which he was to go back and bid Jumbo come up, as Mr Harvey had great confidence in the hunter's shrewdness. Dick presently arrived, and was much impressed with the formidable nature of the obstacle. "We might creep forward," he said, "among the stones and soon drive those fellows off the edge, but they would only lie down behind, and could easily destroy us, as we climbed one by one to the top. Each one, as he got up, would be riddled with assegais. What are you thinking of doing, sir?" "I don't know what is best, Dick. I quite agree with you, it is a tremendous position to storm, but on the other hand it would be almost as bad to retreat." Ten minutes later Jumbo arrived at a run; without a word he threw himself down by the side of Mr Harvey, and for two or three minutes gazed silently at the obstacle ahead; then, to Mr Harvey's surprise, he turned over on to his back, and lay there with his eyes open. "What on earth are you doing, Jumbo?" "Look there, sir," the native said, pointing to a glistening spot, the size of a crown-piece, on his stomach. "Well, what of that?" Mr Harvey said; "that's a drop of rain--there's another fallen on my hat. What do you think of that place ahead?" "Me no think nothing about him, sir; that place, sir, no consequence one way or the other. You hear him, sir?" As he spoke a louder crash of thunder burst overhead. Mr Harvey looked up now. That portion of the sky which could be seen was inky black. Great drops of rain were falling with a pattering sound on the rock. "Storm come, sir; very bad storm. I see him coming, and say to Massa Tom, `Two or tree hour fight over; now you see someting like a mountain-storm. In tree hours water come down twenty feet deep.'"
