He glanced down at the charts and then asked the duty engineer, "How many positions knocked out?"

"No reports from sixty-eight gauges on this last scan," Walt reported, "most of them in Idaho. But there may be a few more before noon tomorrow. According to my last avalanche report before this thing hit, there should be at least ten more cornices that could have been cracked by this shock but that haven't fallen yet. It's still snowing over most of the Sawtooths but it's due to let up by dawn and a warming trend set in. That ought to trigger the others and when they go then we'll have just about all the replacement figures we'll get. What's the chance for more quakes?"

Plumber shrugged. "Seismology says we can expect settling tremblors for as long as four more weeks and possibly even another sharp jolt. I wish those guys were a little more scientific in their predictions."

Troy hid a grin. "Want us to get ready to head back to the hills, Boss?"

"No," Plumber said, "you two stay put for the moment. You just got back and unless I really need you, I want you here for the moment. I'll get a couple of other teams together to take care of the replacements. For the time being, see what you can come up with in some equations for the Pullman-Moscow potential east of the aqueducts. Break it down, stream by stream for me. I can't tell you which systems are going to be functioning or how we'll be able to divert if needed, so keep the equations at gate-head pressures and flow."

The two engineers nodded and headed back to their offices. Alec punched his home number on the vidiphone and Carol's face appeared on the second ring. "Oh, Alec, I'm so glad you called, honey," she said. "I've been worried sick since I heard the broadcast."

"You get that job done that I told you to do before I left," Alec asked.

"All filled," Carol replied with a smile. "What do we do now, darling?"

"You and Jimmy just stay put," Alec warned. "You've got a pretty good supply of food in the apartment right now. In the morning, go down to the store in the building and see what you can buy in the way of staples and long-storage foods. And get all the juices you can. Don't worry about the money end of it now. Spend it like it was going out of style."

"That bad, Alec?"
