Having moved the first Weight to the End of the
Timbers laid for it to slide upon, fix it there with Wedges in such a Manner that nothing can stir it, and then fasten or tie to it the Engines, or Instruments with which you are to draw your other Weight; and thus the moveable Weight will be overcome and drawn along the same Plain by the other Weight, which is no more than equal to it, but only that it is fixed.
