To quickly assess the difficulty of the text, read a short excerpt:
Take the auger as an illustration, the screw-bit taking hold upon the grain of wood draws the cutters or planes of the auger down upon the surface of the wood, cuts away the substance just as thick as the downward tendency of the screw-bit is, while the screw shaped band of auger is of an upward tendency and bears the chips made by the cutting planes at the bottom of the band of the auger, out of the bore made, and thus prevents the clogging or scotching of the cutting planes until at last we h...ave the timber bored through, or as deep as we may desire. Thus in the simple use of the auger we have the principle of the 177 incline [d] plane both as to the straight upward grade and in the form of the screw and the wedge-shaped cutter. Now, the teacher having each tool in hand may explain how the principle of the incline [d] plane enters not only in the raising of weights and adjusting them to higher positions, but also in the division of solid bodies as of wood, stone or metal, the bit of the plane, the chisel and the gouge.
