Without warning there burst upon the night air a loud and sonorous “ker-chew!” Why, it was deep-toned enough to have awakened the Seven Sleepers of old; and certainly the precious pair over there by the fire could not help but be electrified by the explosion.
It was not a thunder clap, though some of the creeping boys might have so considered, when first it broke upon their startled hearing. No, it was only Buster Longfellow sneezing.
This was an old weakness of Buster’s. He was wont to sneeze on any and all occasions, and many times in his past history had he been brought to a knowledge of the fact that it was a habit calculated to get a fellow into all sorts of trouble. Remember that time he threatened to upset George’s boat when one of these fits happened along? Well, there were now even more dire possibilities in store for the unlucky originator of that tremendous sneeze, than he cared to look in the face.
In the first place it aroused the two at the fire. They could be seen suddenly sitting up straight, and looking all around them, as though half expecting to discover strangers in the camp, who according to their calculations could have no business there.
Then a head was seen to rise hurriedly above the gunwale of the white motor boat, showing that the fellow who had gone aboard, had been disturbed in the midst of whatever he was doing. Of course it was to be expected that he would spring over the side, and make a streak for it, intending to find shelter in the covert of nearby bushes.
Nothing of the sort happened.
On the contrary, while he did immediately expose himself in full view it was to carry out an entirely different line of energy.
Jack was just in the act himself of standing up and directing his comrades as to what they should do in order to cut off the other’s escape, when he saw there was going to be nothing doing in that line.
For the man had leaned quickly over the side, and made a sweep with his hand at the little hawser holding the boat snug against the bank. He must have had an exceedingly sharp-bladed knife there, for it cut through that rope as though the cable were made of sand. And at the same moment the white motor boat started to swing free from the shore of the island.
