I still couldn't sleep.


It took me an awfully long time to wake up. When I made it, I found out why.

I'd only been asleep an hour.

"I knew it was too good to last," I said. "What blew up?"

"'Dozer brakes jammed," she said. "Something wrong with the towbar."

That was fine. Perfect operation for twelve days; twenty-six hundred miles covered. Then it had to give trouble.

I rolled out of the bunk. "Well, I didn't think we'd even get this far. Any leaks?"

She shook her head.

Fine. That bar was a nightmare of pressure-actuated hydraulics. Very small, very light, and very precision. I wouldn't dare go into it very deeply.
