[Illustration: FIG. 75.--Turncoat Tom on a Daisy. (Misumena vatia).]
There was no answer. But now gazing steadily in the direction from which the sound came, he saw the dim outlines of a Pixie standing rampant with claws uplifted as though to strike. The mystery of Barck's fall was solved! Junior recognized in the creature before him one of the Laterigrade Legion, a well known character. His uniform was generally yellow, and he was in the habit of ambushing in yellow flowers. The daisy was a favorite resort wherein he would lay alone for many days, hugging the yellow heart of the large flower, and quite concealed from a careless observer. Sometimes he resorted to other plants, and then his uniform took the tint of their flowers, a fact which gave him the popular name of Turncoat Tom.[AN] As Barck had clambered upon the daisy unthinking of danger, Turncoat Tom had struck him on the head, and the mariner, quite off his guard, was knocked to the ground.
"You miserable, sneaking Turncoat," cried the Brownie, wrathful at his friend's mishap. "You shall pay for this dearly!" and thereupon he assaulted the Pixie furiously.
A duel on a daisy! It was a strange occurrence even in Brownie world. The duel was of short duration, for a skillful stroke of Junior's sword severed one of Turncoat Tom's claws, whereupon he sidled, crabwise, over the edge of the daisy, after the fashion of his tribe, and leaped sheer of the flower into the grass beneath, fortunately on the side opposite to where Barck lay. Junior peered over the edge and saw the form of his wounded adversary glide into the shadows and disappear.
"Well," said the Brownie, as he put up his sword, "I dare say that is another of the abandoned sentinels, and he has been punished enough. Let him go!"
He turned once more to survey the fort, which lay under the full light of the moon, quite exposed in every part. It was silent as a cemetery. Not a sentinel was seen at the gates, on the walls, on the towers, or on the parade ground. Not a boat lay at the landing. Not a sign of life anywhere except on the Arenicola tower, where the grim flag of the Pixies floated from its staff, having evidently been left, like the sentinels of the demilune, to keep up the impression that the fort was still occupied.
