"Is the projectile damaged?" asked Mark anxiously.
"Doesn't seem to be—at least, on the outside," answered Jack, as he looked at the huge shape of the Annihilator looming up before him. "But I'm afraid it's all up with Mr. Roumann."
He bent over the German scientist. The man seemed lifeless. There was quite a cut on his head and his clothes were torn.
"He's breathing a little!" cried jack. "We must get Professor Henderson here. He'll know what to do—if anything can be done for him."
"They must have exploded a bomb in here," said Mark, as he looked around at the ruin about, them.
"Something like that," admitted jack. "Here, help me carry Mr. Roumann out of the fumes," for there was a choking smell in the shop.
The two boys found it hard work to carry that limp form out, but they managed it. Just as they got outside the shop they saw Professor Henderson running toward them, followed by Washington and Andy.
"What has happened?" asked the inventor, for he had not been able to learn much from Washington's excited account.
"I don't know," answered Jack. "We heard a explosion, just after we saw two men running away from the shop, and we found Mr. Roumann senseless."
Professor Henderson bent over, and placed his hand on the heart of his friend.
