 that I was commanding had a line, and this line went from my post here in Arizona to a line at a similar latitude in New Mexico. He said it was very fast. He said, I had to go back and forth between these two posts all the time. And I interrupted him. I said, okay, sir, you mean by a line, an underground tunnel, correct? He said, yes. He said, I use it all the time to go back and forth between a post in New Mexico and my post here in Arizona. And again, he wouldn't name the post.
