The arrows presently arrived. He was still engaged in watching the movements of the boat, in an effort to count the crew, when the first of the flaming messengers struck dully against a bowlder and lay there, fiercely blazing.
Then the sudden flight, which, against an inky background, must have presented an extraordinary spectacle, afforded a sight strange enough, as Grenville presently conceded. The pitch and resin with which the shafts were tipped, burned with a black and heavy smoke, that trailed in their wakes like nebulous tails of cloud-producing comets. There were some of the flames that the flight only served to fan to fiercer heat and color. Like a candle sputtering in a draught they sounded as they flew.
Others that lost their yellow blaze smoked the more blackly in the air. In half a dozen different spots the hotly burning lengths of wood were soon consuming bits of scattered leaves and grass, one almost at Grenville's feet.
He was soon convinced that, should this rain of fire be long continued, he should have no need to fire his bombs and spiral. The arrows would actually accomplish the mission for which they were intended. He had no wish for a premature climax to the singular attack, but rather hoped to create the impression he was fighting desperately to protect his magazine.
When a heap of waste and useless creepers was presently ignited, he ran from his place and promptly beat it out. He wished he might be seen. He was gratified without delay. The rifleman, posted, as on previous occasions, in the rocks that crowned the second hill, promptly discharged his erratic weapon, and nearly killed one of his kind.
Grenville ran as if to cover. A shout of exultation came from below. A larger and swifter flight of the blazing shafts immediately ensued.
Sidney now cast a glance about for the ship that was cruising by the headland. Somewhat to his disappointment it had gone about as if to return to the west, from which the cave, his platform, and ladder could not, of course, be seen. He fancied, however, it had come up in stays at the sound of the shot on the hill. It certainly appeared to be paying off to continue about the headland. He dared not longer delay.
The arrows were blazing all about him. He feared at last that one lucky shot might even fire his cannon. Almost amused by the irony of the situation, he caught up the nearest blazing shaft of fire, and used it to light his fuse.
In the briefest time the serpent of fire sped down through the hollowed creeper to the spiral, where, also, lay the bombs. Of a sudden the powder was ignited.
With a flash of quickly leaping flames and a grayish geyser of fume, the destruction began. Then, as a cry of glee arose from the clearing below, the bombs went off in quick succession.
