Early the next morning they bade their Miami friends good-bye, and once more took to the air, this time to complete the last leg of their journey to Panama. It was found that the Sky-Bird's fuel tanks were apparently still full enough to carry them to their destination, so it had not been necessary to store either gasoline or oil in Miami. This was very gratifying, as it showed quite conclusively that, later on in the race, the Sky-Bird would be able to make her longest jumps without the peril of fuel shortage.

At a height of close to two thousand feet they headed across Florida Strait, with Paul at the throttle. It was a real joy to be looking through the glass panels of the airplane's cabin once more, to hear the muffled roar of her engine and propeller, and to realize that probably before dark they would be across the five hundred miles of blue waters of the Caribbean and hovering over the world-famous Canal Zone.

It was a fine morning. What clouds could be seen were well above them—light, billowy, and white, reflecting the sunlight so strongly upon the white-capped waters below, that the sea seemed much closer to the voyagers than it really was.

Shortly after eight o'clock they crossed over the long, low-lying island of Cuba, dipping down close enough to get a fairly good view of the topography. Then rising to three thousand feet, they swerved a little to the eastward and made off across the Caribbean Sea itself.

At a few minutes of eleven they sighted the shore of Jamaica, five miles or so to the eastward of them. Then John took the throttle, both engines were put into the work, and they began to whizz through the air at a clip which would have made them gasp for breath had they been in an open cockpit. As it was, the rush of air as it swept along each side of the fuselage and off its narrowing tail, became a veritable howl in whose noise they found conversation very difficult. Tom Meeks, who was leaning over John's shoulder and watching the instrument-board, triumphantly announced presently that they were traveling at the rate of 280 miles an hour!

For thirty minutes or more John Ross kept the Sky-Bird going at this terrific speed, then he slowed up, and transferred into mono-engine gear, as there was no use in unnecessarily heating the power-plants. As the indicator of the speedometer retreated to 150 miles, he turned the throttle over to Bob Giddings, and said: "Hold her at this rate, Bob; it's plenty fast enough for the present."

It was a little after one o'clock when Paul and Tom announced land to the westward. After looking at the object, which surely had the appearance of land, Mr. Giddings laid down the glasses and consulted the chart.

"That's undoubtedly the outer point of Nicaragua," he said; and upon taking a look themselves with the binoculars, the others all agreed with him.

Keeping the low-lying coastline of the continent on their right, and buffeted considerably by contrary winds which now began to make themselves manifest, Bob threw the automatic-pilot into gear at a suggestion from John, as this insured greater safety, and steered with the rudder only. At once the riding became easier, for the moment a gust of wind hit the machine on one side, the elevators and ailerons shifted and counteracted its uneven effect.

After a while Bob turned slightly to the eastward, and about mid-afternoon they came in sight of Colon, the Atlantic terminal city of the great Canal. Sweeping over its collection of houses, at an elevation of about fifteen hundred feet, they passed the big white Gatun locks, and followed the trail of the Panama Railroad across the great neck of rugged land which joined North and South America—followed, too, the tortuous, wonderful channel which American enterprise had cut through.
