Gavin Brice's aspect of lassitude dropped from him like an outworn garment. For hours—except during his brief encounter with the beach comber—he had been steadily on the move, and had covered a good bit of ground. Yet, any one, seeing him as he traversed the miles from the Royal Palm Park at Miami, would have supposed from his gait that he was on some aimless ramble. Now, alert, quick-stepping, eager, he made his swift way along the windings of the secret path.

Light as were his steps, they creaked lamentably at times on the boards of a bridge-span. More than once, he heard slitherings, in the water and marsh to either side, as some serpent or other slimy swamp-dweller wriggled away, at his passing. The collie trotted gravely along, just in front of him, pausing once in a while, as if to make certain the man was following.

The silence and gloom and sinister solemnity of the place had had a dampening effect on the dog's gay spirits. The backward glances at his self-chosen master were for reassuring himself, rather than for guidance. Surroundings have quicker and stronger effect on collies than on almost any other kind of dog. And these surroundings, very evidently, were not to the collie's taste. Several times, when the path's width permitted, he dropped back to Gavin's side, to receive a word of friendly encouragement or a pat on the head.

Outside of the grove's shadows the sun was sinking. Not with the glowing deliberation of sunsets in northern latitudes, but with almost indecent haste. In the dense shade of the forest, twilight had fallen. But the path still lay clear. And Brice's footsteps quickened, as in a race with darkness.

Then, at a twist of the path, the way suddenly grew lighter. And at another turn, twilight brightened into clearness. A hundred feet ahead was a thin interlacing of moonflower vines, compact enough, no doubt, to prevent a view of the path to any one standing in the stronger light beyond the grove, but making distinct to Brice a grassy clearing beyond.

Upon this clearing, the brief bright afterglow was shining, for the trim grass and shrubs of an upwardsloping lawn were clearly visible. For some minutes the water and the swamp underfoot had given place to firmer ground, and the character of the trees themselves had changed. Evidently, the trail had its ending at that screen of vineleaves draped between two giant gumbo-limbo trees at the lawn's verge.

Thirty feet from the vines, Brice slackened his steps. His lithe body was vibrant with cautious watchfulness. But, the collie was not inclined to caution. He hailed with evident relief the sight of open spaces and of light after the gloomy trail's windings. And he broke into a canter.

Fearing to call aloud, Brice chirped and hissed softly at the careering dog. The collie, at sound of the recall, hesitated, then began to trot back toward Gavin. But, glancing wistfully toward the light, as he started to obey the summons, his eye encountered something which swept away all his dawning impulse of obedience.

Athwart the bright end of the path, sprang a furry gray creature, supple, fluffy, indescribably formless and immense in that deceptive half-light.

Brice peered at the animal in astonishment, seeking to classify it in his mind. But the collie needed no effort of that sort. At first sight and scent, he knew well to what tribe the furry gray newcomer belonged. And, with a trumpet-bark of joyous challenge, he dashed at it.
