More intensely interested than ever, Professor Featherwit plied his shutter, taking shot after shot at yonder aerial phenomena, feeling that future generations would surely rise up to call him blessed when the results of his experiments were once fairly spread before the world.
And hence it came to pass that still more thrilling experiences came unto these daring navigators of space, and that almost before one or the other of them could fairly realise that greater danger really menaced both their air-ship and their lives.
Another whirly-gust of sand and other debris assailed the flying-machine, and while sight was thus rendered almost useless for the time being, the aerostat began to sway and reel from side to side, shivering as though caught by an irresistible power, yet against which it battled as though instinct with life and brain-power.
Once again the adventurers found it difficult to breathe, while an unseen power seemed pressing them to that floor as though--Thank heaven!
Just as before, that cloud was swept away, and again air came to fill those painfully oppressed lungs. Once again the trio cleared their eyes and stared about, only to utter simultaneous cries of alarm.
For, brief though that period of blindness had been, 'twas amply sufficient to carry the aeromotor perilously near yonder storm-centre, and though Professor Featherwit gripped hard his tiller, trying all he knew to turn the air-ship for a safer quarter,-'twas all in vain!
“Haste,--make haste, uncle Phaeton!” hoarsely panted Bruno, leaning to aid the professor. “We will be sucked in and--hasten, for life!”
“I can't,--we're already--in the--suction!”
Whether it was that the air-ship itself had increased its speed during those few moments of dense obscurity, or whether the madly whirling winds had taken a retrograde movement at that precise time, could only be a matter of conjecture; but the ominous fact remained.
The aerostat was fairly over the danger-line, and, despite all efforts being made to the contrary, was being drawn directly towards that howling, crashing, thundering mass of destructive energy.
Already the inmates felt themselves being sucked from the flying-machine, and instinctively tightened their grip upon hand-rail and floor, gasping and oppressed, breath failing, and ribs apparently being crushed in by that horrible pressure.
