The scientist looked up. "It would appear beyond doubt that this bird belonged to the species we call dodos and to which Dr. Beeville has given the excellent scientific name, tetrapteryx.... As the expedition proceeded northward, they encountered more of them; sometimes as many as four being in sight at one time. At Alexandria, where they halted for supplies, the dodos closed in. When the expedition took the air again with the object of flying to Crete and thence to Europe, these remarkable avians came very close, apparently trying to turn the expedition back. They reached Crete that afternoon, in spite of the interference of the birds, but that night were actively attacked on the ground. The phenomena that accompanied all other attacks were observed; the birds used incendiary bombs of great intensity. One machine was entirely destroyed with its aviators. The others, since their object was exploration, at once took to the air and returned.

"Any comments, gentlemen? No? Well the next is the report of the Dutch ship Corlaer, which attempted to reach Japan. She was permitted to proceed to within a few miles of the islands, and then began to receive light-warnings in the sky, such as Captain Entwhistle reports. Unfortunately they were in Japanese characters and there was no one aboard who could read them. She put in at the port of Nagasaki and sent out a landing party. It never returned; as in the other cases the ship was bombed at night and only made Sumatra with the greatest difficulty, one of the bombs having fallen on the quarter-deck, wrecking the steering-gear and causing extensive internal damage....

"There are minor reports with which I will not bother you. But the report of H. M. A. S. Melbourne appears highly significant. She touched at several South American ports. In the cities she reports finding all life at a standstill, although at Iquique, the landing party encountered some hill-Indians who had suffered a bluing of the blood similar to ours, and who proved distinctly unfriendly. They are reported as engaged in looting the city and getting drunk on the contents of the bodegas.

"North of Callao she found no signs of life until she reached San Pedro Bay. There a man was observed to be waving from the beach. The Melbourne put in and launched a boat, but before it reached shore, one of the birds made its appearance overhead and the man disappeared into the trees and was not seen again. From the ship he appeared to be a mechanical man, such as you. Shortly afterward, the Melbourne began to see the dodos constantly, and at the region of San Francisco, she saw one of the light signals. The wording of it was: 'DEPART AWAY FAREWELL FOREVER.'"

Gloria stirred and Sir George looked at her with mild eyes. "Nothing, sir. I was just thinking that these dodos are uncommonly poetical. They told us to fly from the accursed place."

"Yes, yes.... Naturally the Melbourne, not anticipating any trouble as the result of a refusal to obey this absurd command, did not heed the warning, and steamed into the bay. Like the other ships she was attacked at night. One of the bombs fell on the fire-control station and wrecked it, bringing down the tripod mast and fusing the top of the conning tower. She got under way immediately and replied with all guns, but before escaping number three turret was struck by another bomb and all the men in the turret were killed. The roof of the turret was driven in and even the breeches of the guns melted.... That, I think, summarizes the reports we have. We have seen a little of the birds, mostly at a distance, and they appear to have carried off several individuals, especially in Sumatra. I am afraid that is all we can offer."

There was a moment's silence.

"Well, what the material in the bombs is I can't say," said Ben, "but they know all about projecting it from guns in the form of a beam. I told you about my experience in company with the aviator from the Brisbane?"

"The eggs Roberts found, too," said Gloria.

"Oh, yes, Dr. Beeville can tell you about that."
