Curvature of the Earth, Towers, and Mechanisms
Faint red-chalk sketches with a stray word in ink
Faint red-chalk sketches accompany three editorial captions: the curvature of the earth, towers and their connection with the centre of the earth, and mechanisms. At the right a circle drawn about a central point suggests the earth and its centre, while rough tower-like elevations appear below and a beam or frame is laid out at the top. A single word, 'Amando,' is written in darker ink beside the drawings; further faint marks are present that the bundle does not transcribe.

Towers and their connection with the centre of the earth
The sheet is captioned with the curvature of the earth and with towers linked to the earth's centre. At the right, a circle is drawn about a distinct central point, evoking the globe and the line running to its middle. The idea joins the vertical of a standing tower to the earth's centre of gravity.
Rough elevations of towers
Below the central diagonals, faint red-chalk sketches read as the elevations of tall structures or towers, with vertical shafts rising from a base. They correspond to the caption on towers. The strokes are light and summary rather than measured.
Beam or frame captioned as a mechanism
Across the top a long horizontal member is drawn with a diagonal strut, in keeping with the caption 'mechanisms.' It reads as a beam or framed device rather than a finished machine. Like the rest of the page it is sketched quickly in red chalk.
