But when events are moving fast, and disaster stares one in the face, details and trifles escape attention. Jim and his comrades had their safety to think of, so that it is not wonderful that they failed to observe too closely the appearance of their dusky enemies. But however urgent the position, none could fail to see the short spears, with long narrow blades attached to them, which each dusky warrior carried. Half a dozen at least were gripped in each left hand, while the right held a single one in readiness to discharge it. As for the gun, the cheap gas barrels with which these wretched natives had been supplied, they were without exception muzzle loaders; and now that events were moving so fast and so furiously there was hardly time to load. A few of the men handled their ramrods, but the rest had discarded their weapons and stood prancing upon the deck of the launch, causing her to heave and roll dangerously, and prepared to throw their spears the instant they came within range of Jim and his party. It was not until that moment that our hero realized that if their fortunes were desperate they were at least lucky in one particular. "Gee, ain't I glad!" he exclaimed. "From what Phineas told me I quite expected them to be armed with bows and arrows--the latter poisonous. Tomkins, you and your men had best concentrate your force aft of the launch, where the engine is. I caught a glimpse of those rascals there; and though I don't suppose that the death of one or both would cause the gang to sheer off, yet it might do so, and in any case if we could put them out of action there would be no white man to lead the natives." "Right, sir, right," came from Tomkins instantly, while he and his two comrades promptly moved to the back of the cab, from which point they could best command that portion of the launch upon which they were instructed to concentrate their fire. "You, Tom and Sam, fire on the natives," shouted Jim. "I'm going to help you. Ching, get hold of some of that clean cotton waste and wipe up all round this magneto. Dry every part you can, and don't forget those plugs on top of the cylinders." He had already pointed out the ignition plugs to the Chinaman, for they, like the rest of the engine, had been heavily sprayed with water. Then he seized a rifle, jerked the magazine open as the Major had instructed him when they first set out on the expedition, and levelled his sights upon the advancing natives. By now the latter were dangerously near, and already clouds of spears were flying. It looked as if within a few seconds the steam launch would be right alongside, and the black demons aboard her hurling themselves upon the decks of the motor. But suddenly there came a high-pitched shriek amidst the howls of the enemy, and to the relief of all in Jim's party the course of the other vessel was abruptly altered. She shot away obliquely to the left, while one of the white men who had been manning the wheel was seen to tumble backwards.
