I rented the parlor bedroom the next day to a school-teacher, and I found the periscope affair very handy.

No huddling in muddy trenches here, waiting to be smashed by jagged chunks of ironeverything clean, aloof, scientific, exact, a matter of fine wires crossing on a periscope lens, of elevation, wind pressure, and so on, and everything in the wide outdoors, and done, so to say, with a magnificent gesture.
