The cries came from the aerodrome and were uttered by the awakened Schultz and Le Blanc, the latter of whom was almost in hysterics. Frank laughingly quieted them and explained what had happened.

“Ve vos only eggcited on your aggount,” remarked Schultz bravely when he learned that all danger was over.

“Comment, vee fight lek ze tiger-r-r n’ c’est pas?” demanded Le Blanc, flourishing a pillow fiercely. “A pitee I deed not see zee ras-cals.”

CHAPTER VI.
THE START FOR THE ’GLADES.

The incident related in the last chapter determined Frank to abandon his half-arrived at intention to enter the Everglades from the Atlantic side. The appearance of the dark man in Washington—he was now certain their plans had been overheard—the episode of the tramp and the attempt to blow up the aerodrome all combined to convince him that his original scheme of invasion of the little known wastes of Southern Florida was as an open book to the men who had only too evidently their destruction at heart.

A hasty trip to Washington resulted, and a consultation with the Secretary of the Navy. The result was that arrangements were made whereby the boys’ expedition was to gather at Miami as openly as possible, and then under cover of night run down Biscayne Bay and eventually double Cape Sable by the inland passage. Then they were to beat up through the Ten Thousand Island Archipelago to the mouth of either Shark or Harney River and thence into the trackless wastes of unmapped swamp and saw-grass known as the Everglades.

The Tarantula was to cruise off and on around the coast and in case of dire need was to be signaled by wireless. These details completed, Frank and Harry returned to New York and a week later, the Golden Eagle II being completed, and loaded in small cases marked “Glass, Fragile,” and other misleading labels, the Boy Aviators bade farewell to their mother and friends and started by the Southern Limited for Miami. With them they carried in ordinary trunks their mess and camp kit outfits, rifles and medical supplies as well as two of the Government’s field wireless outfits. The rest of the party was to follow a week later in a private car with all the other baggage, including the boxed sections of the Golden Eagle II. The canoes and boats for the trips were to be purchased at Miami or along the coast in the vicinity, as the boys deemed fit. In the meantime the Tarantula had been dispatched from Hampton Roads for Southern waters under sealed orders. Not till her commander opened his instructions at sea did he know the real nature of his errand.

At this point it may not be amiss to give a brief description of the little known country to which the boys were bound. Everyone has heard of the Everglades, few have any accurate idea of them beyond a sort of hazy conception of a vast tract of morass, overgrown with giant forests and rank growth of all kinds. Nothing could be further from the truth.

It is without doubt the peculiar, even extraordinary, character of this great stretch of country that has caused its geography to remain obscure. Even recent maps are extremely inaccurate. It seems remarkable in these days of African and Polar discovery that here in our own country is a vast waste, 130 miles long and 70 wide, that is as little known to the white man as the heart of the Sahara. The Everglades are bounded on the north by Lake Okeechobee, on the east by a belt of scrub pine-land about six miles wide facing the Atlantic, on the south by the great mangrove swamps facing the Bay of Florida and the Gulf of Mexico, and on the west by the Big Cypress Swamp which runs right up to the uninhabited region verging on the west coast of the peninsula.

The prevailing idea that the Everglades are unhealthy is about as far as it is possible to get from the truth. So far as the few expeditions that have penetrated the great mystery have reported, the water is fine and the air healthful. The saw-grass, the Seminoles and the snakes—rattlers and cotton-mouth moccasins—are the worst enemies the explorer ordinarily encounters, with an occasional panther.
