"Very well," said the big fellow, standing up very straight and rather sidewise, as he held his bow at his left arm's length, slowly drew the arrow to the head, and then as Robin gazed in the direction of the indistinctly seen hat hanging on the tree-trunk—

Twang!

The arrow had been loosed, and the bow had given forth a strange deep musical sound.

Robin looked sharply at Little John, and the big outlaw looked down at him.

"Where did that arrow go?" said the boy.

"Let's see," said Little John.

"I don't think we shall ever find it again," continued Robin.

They walked back, the outlaw very slowly, and Robin quite fast so as to keep up with him.

"Perhaps not," said Little John, "but I don't often lose my arrows."

"This one has gone right through the ferns," thought Robin, and he felt glad with the thought of the big fellow having missed the mark, but as they walked nearer, he kept his eyes fixed upon the great trunk dimly seen in the shade, being tripped up twice by the bracken fronds; but he saved himself from a fall and watched the tree trunk still, while the hat hanging on the old bough grew plainer, just as it had been before.
