Faint erased sketches; sheet catalogued without writing
An inverted sheet bearing pale framed-structure sketches and a red-chalk circular plan
The sheet is catalogued as devoid of writing and reproduced upside down, but it still carries faint, partly erased sketches. In the ink work one can make out framed structures with taut lines and hatched wedge-shaped forms suggesting hoisting or trestle-like apparatus, together with the number 130. At the right a pale red-and-violet chalk drawing lays out a circular plan with concentric and radial lines beside a rectangular block. A few illegible lines of mirror-writing survive at lower left; these and the drawings are untranscribed and are described here only from the image.

Faint framed structures with taut lines and hatched forms
Across the ink drawing appear framed, trestle-like structures braced by taut lines, with hatched wedge-shaped forms and a booms-and-legs arrangement suggesting a hoisting or lifting apparatus. The forms are pale and partly erased, and the sheet is reproduced inverted, so their function cannot be read with certainty.
Red-chalk circular plan at the right
At the right edge a drawing in pale red and violet chalk sets out a circular plan with concentric and radial divisions beside a rectangular block. It reads as a ground plan of a round structure, though the faintness of the chalk leaves the reading tentative.
