"I suggest we also save time by shooting in the early morning," Hartson Brant added. "That will leave the afternoon for other activities. Jeff, if you can manage to keep your head out of the way of blunt instruments, perhaps you'd like to make a better sketch of the magma front. We can assign the boys as guards, if you like."

Dr. Williams caressed the bruise on his head. "Not necessary, Hartson. I'll lock my door and keep my face toward the window. But for now, how about dinner?"

After dinner, Rick and Scotty lingered over coffee with Dr. Balgos, Julius Weiss, and Hartson Brant. The others had excused themselves and gone back to their rooms. The boys were trying to learn more about volcanoes, but the scientists had a tendency to get involved in discussions of some of the finer points of geophysics and long minutes would pass before Rick or Scotty could bring them back to the main point with a question.
