“Captain Mango!” cried Don, as though seized with some sudden inspiration. “Never thought of him until this minute!” and, clapping on his helmet, he set off at a run after Puggles and the monkey.

Away like the wind went the monkey, the stolen turban trailing after him through the sand like a great serpent; and away went Puggles, his back hair flying. But while Puggles was short of wind, the monkey was nimble of foot. The race was, therefore, unequal from the start, its finish more summary than satisfactory; for as Puggles ran, with his eyes glued upon the scurrying monkey, and his mouth wide-stretched, his foot unluckily came in contact with a tree-root, which lay directly across his path. Immediately beyond was a bed of fine soft sand, and into this he pitched, head foremost. Just then his master came up, with Jack at his heels.

“Sa'b! Sar!” spluttered Puggles, knuckling his eyes and spitting sand right and left, “debil monkey done stole turban. Where him going, sa'b?”

“Come on, Pug,” his master called out as he ran past; “your headgear's all right—the monkey's taken it into the fort.”

The structure known as “the fort” occupied the summit of a sandy knoll, about which grew a thick plantation of cocoanut palms, seemingly as ancient as the fort itself. The walls of the enclosure had so crumbled away in places as to afford glimpses of the buildings within. These were two in number—one an ancient godown, as dilapidated as the surrounding wall; the other, a bungalow in excellent repair, blazing in all the glory of abundant whitewash.

Towards this building, after passing the tumble-down gateway, with its turreted side-towers alive with pigeons, Don and his companion shaped their course; for this was by no means their first visit to the fort. A broad, low-eaved verandah shaded the front of the bungalow, and upon this opened two or three low windows and a door. As they drew near a shadow suddenly darkened the doorway, and there emerged upon the verandah an individual whose pea-jacket and trousers of generous nautical cut unmistakably proclaimed him to be a seafaring man. About his throat a neckerchief of a deep marine blue was tied in a huge knot; while from beneath the left leg of his wide pantaloons there projected the end of a stout wooden substitute for the real limb.

On catching sight of his visitors an expression of mingled astonishment and pleasure overspread his honest, bronzed features.
