"See no reason why not. I've heard of using glass gauges, and they've got some good reasons, too. Tell him to go ahead."
"Kingman? How soon can we get glass ones?"
"Horman, how soon on the glass blocks?"
"Two dozen? About a week."
"We'll have your blocks on the way within four days, Channing. Four days minimum, plus whatever wait is necessary to get 'em aboard a spacer."
"We'll check from this end on schedules. We need the blocks, and if the wait is too long, we'll send the Relay Girl in for 'em."
Don hung up and then said: "Glass ones might be a good idea. We can check the transmission characteristics optically. I think we can check more, quicker, than by running analysis on steel."
"Plus the fact that you can get the blocks back after test," grinned Walt. "Once you tear into a steel block to check its insides, you've lost your sample. I don't know any better way to check homogeneity than by optical tests."
"O.K. Well, four days for glass blocks will do better than a couple of months on steel blocks."
"Right. Now let's look up Wes and see what he's come up with."
