Board joints rated for strength
Four board joints graded from good to poor
The page continues the study of how boards are joined, grading four of them as nearly good, good, nearly good, and poor. Long planks with interlocking ends fill the upper sheet, alongside small plate-like fittings pierced by holes. A circle divided by radiating strokes is drawn at the foot of the page; the transcription gives no text for it.
