• "_Take implements_ the gunner stepped to the cascabel and handed the vent-cover to No. 2; the tube-pouch he gave to No. 3; he put on his fingerstall, leveled the gun with the elevating screw, applied his level to base ring and muzzle to find the highest points of the barrel, and marked these points with chalk for a line of sight."
• "Here and there, on the dry bank over which the clematis projected like an eave, there stood tall campanulas, their blue bells as large as the fingerstall of a foxglove."
