Pendulum pumps for raising water, and a scatter-shot bombard
Two stone-weighted pendulum water pumps above a wide-mouthed bombard
Two pendulum-driven pumps for raising water are drawn at the top of the sheet: a large one set in a rectangular frame, whose stone-weighted pendulum works a rounded basin below, and a smaller suspended device beside it that serves the same purpose. Both are captioned simply as devices for raising water. Along the foot of the page a bombard is sketched as a long tube charged with loose stones and a round ball. The note advises widening its mouth so the discharged shot scatters and, in desperate cases, loading a stump of oak root or half a bombard ball.

Pendulum pump loaded with stones, for raising water
A tall pump stands within a rectangular frame, its central pendulum weighted so as to work a rounded basin below. The caption states its purpose is to raise water.
Second pendulum pump
A smaller suspended apparatus with paired buckets hangs from a cross-frame at the left. The note says it serves the same purpose as the first.
Wide-mouthed scatter-shot bombard
A long bombard charged with loose stones and a round ball is drawn along the foot of the page. The note advises making the mouth somewhat wider so the discharged stones spread out, and loading a stump of oak root or half a bombard ball in desperate cases.
