To quickly assess the difficulty of the text, read a short excerpt:
The length of this third side is fourteen inches and one-half. The fourth side of this mould-board is horizon- tal, or nearly so, extending from the upper- most point of the third side, to the fore part, or pitch, eighteen inches. The fifth, or last side, descends or slopes from the last mentioned mark, spot, or pitch, to the place of beginning at the low and fore point of the mould-board, where it joins the land side, thirteen inches. //\^' "Besides these properties and pr6pOFtiSip^oJj *p y N ...his mould-board, the said Jetriro Wood f ncn$> ^. Explains other properties which it possei^sES^ and by which it may be and is distinguished from every other invented thing. The pecu- liar curve has been compared to that of the 26 JETHRO WOOD; screw auger ; and it has been likened to the prow of a ship. Neither of these similitudes conveys the fair and proper notion of the inven- tion.
" The mould-board, which the said Jethro Wood claims as his own, and which is the result of profound reflection and of numberless experiments, is a sort of piano-curvilinear sur- face, as herein-before stated, having the follow- ing bearings and relations : A right line, drawn by a chalked string or cord, or by a straight rule, diagonally or obliquely upwards and backwards from a point two inches and a half inch above the tip or extremity of the mould-board to the angle where the third and fourth sides of the mould-board join, touches the surface the whole distance, in an even and uniform application, and leaves no sinking, depression, hole, cavity, rising, lump, or pro- tuberance, in any part of the distance.
