CHAPTER XXI

THE DOUBLE LOOP

For a moment or two John and Bob stared at Paul blankly, unable to

comprehend the import of his announcement. Tom was at the throttle,

and while he had heard the startling words, he was too occupied in

guiding the Sky-Bird to do anything except take a quick glance backward.

"A snake?" repeated Bob.

"Not on the machine?" cried John.

"Yes," Paul said, with a seriousness which left no further doubt as to

the truth of his statement. "He's a whopper--must be twelve or

fourteen feet long and as thick as my leg. He's there on the fuselage

just outside of the window, hanging on for dear life. If I hadn't shut

that window just as I did, I believe he would have crawled in here in a

minute."

John and Bob now hurried to the window and looked out. In the

moonlight they could distinctly see a huge reptile, either a python or

a boa-constrictor, coiled up in the angle formed by the juncture of the

airplane body and the broad base of the left wing. The creature was so

long that its tail passed up over the rounded fuselage and out upon the

other wing. Bob flashed his electric pocket lamp upon it, and by the

yellow and brown mottled spots upon its body and the double plates of

whitish scale at its tale, and the wicked-looking triangular head, they

were sure it must really be a python, one of the most dreaded of

African snakes. These creatures think a monkey a very choice morsel of

food, and undoubtedly it had been attracted to the airplane, while it

stood in the grass, by the appearance of Grandpa in the open cabin

window, but had been frustrated in its designs by the return of the

flyers and the sudden rising of the machine.

Now, with the window shut, the boys seemed safe enough for the present.

They could see that the big snake was extremely uneasy. As the wind

whistled by him, his great tail twisted and untwisted, and he seemed to

be trying to get a better hold on the smooth surface, while his beady

eyes glared at them only a moment in the glow of the flashlight, and

then he transferred his attention to the landscape below them. His

forked fangs darted in and out during this time with the angriest

lightning-like movement.

Paul relieved Tom at the throttle for a few minutes, so that the latter

could have a look at the reptile.

When Tom came back again to his post, he said, with plain uneasiness:

"I never saw such a big snake before, Paul. Between the rush of wind

and the roar of the engine and propeller, he seems scared out of his

wits."

"We've got to get him off of there somehow--and mighty soon, too," put

in John, with decision. "Tom, if that monster should begin to slip a

little most likely he will coil his tail around some of our control

wires,--and then what?"

Their faces blanched at this prospect. They knew what that would mean.

It would mean that the great creature would either operate the

airplane's rudders when they should not be operated, or would prevent

Tom from moving them when they must be moved. In either event, the

result would be disaster to machine and crew.

"Good heavens, boys!" said Tom, so nervous his voice shook, "get rid of

that snake as quick as you can!" He fancied he could see the rear

control levers moving at that instant.

The other three flyers knew the importance of these instructions, but

how were they to carry them out? The reptile was too large to be

shoved off with a stick or pole, and would probably squirm through the

window while they were attempting it. And they were afraid to use a

gun, as, in the case of a miss or a little lurch of the airplane at the

moment of firing, the bullet might puncture the hollow wing or rear

fuselage and let helium escape.

It was Bob who solved the puzzle.

"Why not try a loop or two?" he asked.

Their hearts jumped with hope at this. So everything was made tight in

the cabin, with the straps and fastenings which had been provided when

the machine was made. Even Grandpa had to submit to being roped up in

one of the swinging hammocks. When the boys had buckled themselves

down to their seats, John gave Tom the word, and he began to rise

slowly. At close to two thousand feet he brought the Sky-Bird quickly

and smoothly upward until she stood almost on her tail end.

Then Tom threw the elevators and ailerons hard up, and held them there.

They were going at a rate of close to a hundred miles an hour at the

moment, and their velocity brought them around in a pretty loop. There

was no way for them to tell if the serpent had been dislodged, so, to

make as sure as he could of accomplishing his purpose, Tom kept his

controls as set, and they made another or double loop.

This time he straightened out his controls as he came up to the

horizontal, and they ran swiftly ahead again on a level keel.

His companions quickly unloosened their straps, and ran for the rear

window. A feeling of the greatest thanksgiving filled their souls and

joy lit up their faces. The python was gone! He had hurtled through

the air during one or the other of the loops, and his long sinuous body

was probably at that moment lying crushed upon the hard ground, or

impaled upon the sharp stub of some forest tree, far below.

It had been a night of intense excitement. Now that they began to beat

through the air in the old tuneful way, and there was nothing more to

claim their attention until they should arrive at Aden sometime in the

morning, Bob and Paul took to their hammocks for sleep, but first Bob

got Khartum on the wireless and delivered their position and a brief

description of their adventures. As may be imagined, however, the two

youths did not shut their eyes immediately. There was much to think

about and to talk about before even fatigue could get the better of

them.

Tom put the Sky-Bird through on a straight course for Aden as fast as

he dared run the night engine, which was very close to its limit, now

that it had had a chance to cool off and was well supplied with water.

It was important that they should make speed, for in the stop for water

and the subsequent maneuvering to rid themselves of their unwelcome

passenger, the python, they had lost upwards of an hour's time.

Flying high, and depending entirely upon the compass for striking Aden,

they shot through the starlit tropical night like a meteor, showing no

lights except the two small ones on the dashboard in the cabin, by

means of which Tom could observe the instruments and the controlling

levers below. Thus they crossed the famous Nile, sweeping below

Khartum and across the plains of Kordofan, and when the first streaks

of daylight appeared ahead of them they were just entering the plateaus

of northern Abyssinia.

Paul and Bob now relieved Tom and John, and the latter young men took a

nap. It was their custom to work in pairs, the observer preparing food

for himself and the pilot during the course of flight. Sometimes the

observer took the throttle long enough to give his friend a chance to

eat, and sometimes the pilot retained his seat, allowing the automatic

arrangement to do the guiding for him while he munched his food.

Just before seven o'clock Paul and Bob saw two large bodies of water

ahead of them, one stretching to the right and the other to the left.

The chart told them that the northern body was the Red Sea and the

southern one the Gulf of Aden, which opens into the Indian Ocean.

Between these bodies lay a narrow belt of water, flanked on the western

or African side by rocky, wooded hills, and on the eastern side by low,

sandy shores dotted with palms. This was the Strait of Bab-el-Mandeb,

and the country beyond was Persia.

Aden could not be more than fifteen minutes' run east now, and so Bob

awakened his sleeping comrades while Paul guided the airplane across

the strait. They flew a little higher, later, following the general

contour of the terraced slopes of the mountains along the Arabian coast.

As the Sky-Bird came leisurely over the hills surrounding this British

seaport of Aden, they could see that the town nestled in the crater of

an extinct volcano, as they had read. All around the low, white

buildings spread the rugged hillsides, and in declivities they passed

over numbers of the great brick tanks or reservoirs which catch and

store the scanty rainfall of the region and thus furnish Aden with its

only water supply.

The flyers saw many gowned figures, some on camels, pause to look

upward at them, as they began to circle the town in quest of their

landing field. Bob was the first to discern it--a fairly level stretch

in the southern end of the valley or basin, marked in the way agreed

upon, and containing two small buildings, neither of which was large

enough to admit the machine.

But they cared nothing for shelter for the Sky-Bird, as they did not

purpose staying any longer than necessary for fuel replenishment and

news dissemination by telegraph and letter. So they quickly settled

down in the midst of a wondering ring of Arabs.

Mr. Griggs, the American consul here, now came forward with a couple of

British military officers, and the flyers met with a hearty reception.

It seemed good to run upon one of their own countrymen again, after

seeing so many strange faces since leaving Panama. Mr. Griggs insisted

upon their going to his home with him for breakfast, and to this they

consented as soon as they found he had made full arrangements for

having some British workmen at the garrison refill the Sky-Bird's tanks.

They found that their rivals had arrived just after daylight, and had

departed for Colombo, Ceylon, less than twenty minutes before their own

appearance. This was cheering news. They had gained a lot on them in

crossing the African continent.
