Tools for Digging, Gravel-Moving and Demolition
Ploughs, forks, spades, a rake and mauls for canals and foundations, with an arched window
This sheet gathers earth-working implements labelled by Leonardo: an ox-drawn plough for cutting a channel through gravel, forks 'for gravel,' four spades, a rake, a spoon-shaped shovel, a maul with wedges, a water-barrow and tools for demolishing foundations. A note by a ruined wall explains that to throw a wall to the ground one takes powder and proceeds as drawn above. The sheet also carries architectural and geometric sketches not in the transcription — a tracery-filled round-arched window and a ribbed half-dome — as well as lines of mirror-script.

Ox-drawn plough to cut a channel through gravel
A kind of scoop or bucket and gravel is drawn below, captioned with the note that a plough drawn by oxen serves to make a channel through the gravel. It belongs to the sheet's earth-moving repertoire.
Throwing down a wall with powder
The note by the ruined wall says that to cast a wall to the ground one takes powder and does as is figured above. It pairs demolition by powder with the mauls and wedges drawn nearby.
Forks, spades, rake and spoon-shaped shovel
Several digging and raking tools are laid out: forks marked f are labelled 'for gravel,' four spades are lettered K, h, g and l, a rake is marked m, and a spoon-shaped shovel carries the letter q. Together they form a kit for moving earth and gravel.
Tools for demolishing foundations
A figure of foundations, marked 3 braccia, is captioned 'to demolish foundations.' A maul with wedges and a beam with stakes are set alongside as the demolition tackle.
Arched window with tracery and a ribbed half-dome
At the lower left the sheet bears an ornate round-arched window filled with tracery, and beside it a fan-shaped ribbed half-dome. These architectural sketches are not covered by the transcription.
