He rubbed his eyes and looked around.
Coming towards him at his right hand was an immense bird, whose body seemed almost as big as that of a horse. Its wide-open, curving beak was set with rows of pointed teeth, and the talons held against its breast and turned threateningly outward were more powerful and dreadful than a tiger's claws.
While, fascinated and horrified, he watched the approach of this feathered monster, a scream sounded just behind him and the next instant the stroke of a mighty wing sent him whirling over and over through the air.
He soon came to a stop, however, and saw that another of the monsters had come upon him from the rear and was now, with its mate, circling closely around him, while both uttered continuously their hoarse, savage cries.
Rob wondered why the Garment of Repulsion had not protected him from the blow of the bird's wing; but, as a matter of fact, it had protected him. For it was not the wing itself but the force of the eddying currents of air that had sent him whirling away from the monster. With the indicator at zero the magnetic currents and the opposing powers of attraction and repulsion were so evenly balanced that any violent atmospheric disturbance affected him in the same way that thistledown is affected by a summer breeze. He had noticed something of this before, but whenever a strong wind was blowing he was accustomed to rise to a position above the air currents. This was the first time he had slept with the indicator at zero.
The huge birds at once renewed their attack, but Rob had now recovered his wits sufficiently to draw the electric tube from his pocket. The first one to dart towards him received the powerful electric current direct from the tube, and fell stunned and fluttering to the surface of the sea, where it floated motionless. Its mate, perhaps warned by this sudden disaster, renewed its circling flight, moving so swiftly that Rob could scarcely follow it, and drawing nearer and nearer every moment to its intended victim. The boy could not turn in the air very quickly, and he feared an attack in the back, mistrusting the saving power of the Garment of Repulsion under such circumstances; so in desperation he pressed his finger upon the button of the tube and whirled the instrument around his head in the opposite direction to that in which the monster was circling. Presently the current and the bird met, and with one last scream the creature tumbled downwards to join its fellow upon the waves, where they lay like two floating islands.
Their presence had left a rank, sickening stench in the surrounding atmosphere, so Rob made haste to resume his journey and was soon moving rapidly eastward.
He could not control a shudder at the recollection of his recent combat, and realized the horror of a meeting with such creatures by one who had no protection from their sharp beaks and talons.
"It's no wonder the Japs draw ugly pictures of those monsters," he thought. "People who live in these parts must pass most of their lives in a tremble."
The sun was now shining brilliantly, and when the beautiful islands of Japan came in sight Rob found that he had recovered his wonted cheerfulness. He moved along slowly, hovering with curious interest over the quaint and picturesque villages and watching the industrious Japanese patiently toiling at their tasks. Just before he reached Tokio he came to a military fort, and for nearly an hour watched the skilful maneuvers of a regiment of soldiers at their morning drill. They were not very big people, compared with other nations, but they seemed alert and well trained, and the boy decided it would require a brave enemy to face them on a field of battle.
Having at length satisfied his curiosity as to Japanese life and customs Rob prepared for his long flight across the Pacific Ocean.
By consulting his map he discovered that should he maintain his course due east, as before, he would arrive at a point in America very near to San Francisco, which suited his plans excellently.
