they snorted along big drifting cakes of ice.

At her pier, a short distance below the Brooklyn Bridge, the steamer Aztec, of the Central American Trading Company’s line had just blown a long, ear-piercing blast—the signal that in half-an-hour she would cast off her lines. In the shrill summons there was a note of impatience; as if the ship was herself as eager as her fortunate passengers to be off for the regions of sunshine and out of the misery of the New York winter.

The Aztec had been due to sail at noon that day, as the Blue Peter floating at her mainmast head had signified. Here it was, however, a good hour since the towering mass of skyscrapers on the opposite side of the river had blossomed, as if by magic, into a jewel-spangled mountain of light and her steam winches were still clanking and the ’longshore men, under the direction of the screech of the boss stevedore’s whistle, as hard at work as ever. No wonder her passengers fretted at the delay.

Not the least eager among them to see the ship’s restraining lines cast off were Frank and Harry Chester, known to the public, through the somewhat hysterical pæans of the Daily Press and the rather more dignified, but not less enthusiastic articles of the technical and scientific reviews, as the Boy Aviators. It was an hour since they had bade their mother and an enthusiastic delegation of boy and girl friends good-bye.

Side by side the youths paced the deck muffled in huge overcoats and surveying anxiously, as from time to time they approached the forward end of the promenade deck, a lofty pile of boxes that contained the various sections of their aeroplane the Golden Eagle which had made the sensation of the year in aviation circles.

Ever since the Golden Eagle, a biplane of novel construction, had carried off from all competitors the $10,000 prize for a sustained flight offered by J. Henry Gage, the millionaire aeronaut at the White Plains Aerodrome, the boys had become as well-known figures in New York life as any of the air prize contestants during the Hudson-Fulton Exhibition. Frank, the eldest, was sixteen. A well-grown, clean-lived-looking boy with clear blue eyes and a fearless expression. His brother, a year younger, was as wholesome appearing and almost as tall, but he had a more rollicking cast in his face than his graver brother Frank, whose equal he was, however, in skill, coolness and daring in the trying environment of the treacherous currents of the upper air.

With the exception of a brief interval for lunch the two boys had amused themselves since noon by watching the, to them novel, scene of frantic activity on the wharf. The ships of the Central American Trading Co. had a reputation for getting away on time and the delay had grated on everybody’s nerves from the Aztec’s captain’s to the old wharfinger’s; in the case of the latter indeed, he had attempted to chastise, a short time before, an adventurous newsboy who had ventured on the pier to sell his afternoon papers. Frank had intervened for the ragged little scarecrow and the boys had purchased several copies of his wares. They had a startling interest for the boys which they had not suspected. In huge type it was announced in all, that the long threatened revolution in Nicaragua had at last broken out with a vengeance, and seemed likely to run like wildfire from one end of the turbulent republic to the other. Troops were in the field on both sides—so the despatch said—and the insurgents were loudly boasting of their determination to march on and capture Managua, the capital, and overthrow the government of President Zelaya. Practically every town in the country had been well posted with the manifesto of the reactionaries,
