"Please find out if any of those ships they are building have ever left the ground."

"Some little ones only," Geck reported after awhile. "Some few disappear into sky then come back after time, then do same again."

Trial trips, or training trips for the crews, Hanlon deduced.

Well, he had some data now, at least. Enough so that once he got that news to Headquarters they would attack this place in force great enough to stop this work ... IF ... he could get word to them soon enough.

"Let's see now," he figured quickly. "I've been here almost twelve weeks. That means another six or seven until I'm supposed to be eligible to get back to Simonides. Hmmm. Wish I knew how near finished those big battle-wagons are."

More moments of intense thought. "I don't dare take the chance of trying to sneak off to the yards," he reasoned logically. "I've got to do everything I can to make sure I get my trip back when my eighteen weeks are up. If I got caught off bounds that would ruin everything—I'd really be in a mess."

Also, even if he could get to the shipyards, the moment he was spotted trying to get inside any of those ships he would undoubtedly be killed by guards who would certainly shoot first and ask questions later—if any.

Nor were there any longer any native birds or animals left on Algon he could use—he had learned that the men had killed them off soon after they arrived.

"No, I'll just have to keep on trying, and get what dope I can without exposing myself. With a month and a half I should be able to get a lot more, and with what I already know, the Corps top brass will take steps, but fast!"

Suddenly a new idea sprang into his mind. Where was "here?" In his excitement and planning he had entirely forgotten to finish figuring out that point.
