"Lie low!" exclaimed Henry. "Everybody down behind the sides of the boat! They may fire at any time!"
The boat was built of thick timber, through which no bullet of that time could go, and they crouched down, merely peeping over the edges and presenting scarcely any target. They had their own rifles and the extra fowling pieces and pistols were made ready, also.
But nothing came from the great pall of whitish fog, and the silence was chilly and heavy. It was the most uncanny thing in all Paul's experience. Beyond a doubt they were surrounded by savage enemies, but from which side they would come, and when, nobody could tell until they were at the very side of the boat.
"How many did you see, Sol?" whispered Henry.
"Only two, but one of 'em won't ever attack us again."
"The others must be near by in their canoes, and the swimmers may have been scouts and skirmishers. They know where we are, but we don't know where they are."
"That's so," said Shif'less Sol, "an' it gives 'em an advantage."
"Which, perhaps, we can take from 'em by moving our own boat."
Henry was about to put his plan into action, but they heard a light splash in the water to the west, and another to the north. Spots of piercing red light appeared in the fog, and many rifles cracked. Fortunately, all had thrown themselves down, and the bullets spent themselves in the wood of the boat's side. Henry and Sol and Tom fired back at the flashes, but more rifle shots came out of the fog, and those on the boat had no way of telling whether any of their bullets had hit.
"I think we'd better hold our fire," whispered Henry between rifle shots. "It's wasting bullets to shoot at a fog."
