Once the hawsers were loosed, they shot off the ground like an arrow. Not until their ascent became slowed did the professor and his companions cast out the large stones they carried for ballast.
One of the great birds dropped down to meet them and was blasted from the sky. Another flew croaking from their path in alarm. They were nearly six miles above the ground before the balloon stopped rising.
With powerful glasses, they examined the terrain for several hundred miles in every direction except towards the mountains. A pall of cloudy mist hung among the peaks. In the opposite direction, their horizon was far-flung due to the enormous size of the planet.
With their scientific apparatus, they gathered data which they were unable to obtain from the ground and had been too involved and disinterested to notice during their perilous descent.
A bevy of the huge birds came to investigate, interrupting their observations to circle, growl and chatter at them. One of the winged monstrosities made a purposeful lunge at the metal ball above their heads, and they blew him to fragments with rapid and well-directed fire. Another met the fate of the first, before the others winged away in screaming anger and alarm in the direction of the mountains.
"Do you think we could deal with them if they attacked us in large numbers?" 12W-62 queried.
"Not if they attacked us in a mass," the professor replied. "But we can descend by freeing some of the helium if they become too numerous or troublesome."
A sudden gust of air swayed the basket. The breeze had freshened, and they found that they had been drifting towards the mountains.
Like stately spires, the mountain peaks loomed before and above them. Those in the background were lost in a gray fog which had crept among them since the machine men had risen in their balloon.
Hundreds of the great birds could be seen darting and wheeling above the mountainside. As the balloon was carried nearer by the rising wind, they spread on the wing and flapped about the strange invader, voicing their weird cries and veering menacingly about the metal globe and basket. Several of them attacked and were destroyed.
