I flatter myfelf there- fore, that I am doing a benefit to fociety in endeavouring to fimplify this machine, and to increafe its accuracy as much as pofhble: and fhall therefore here defcribe another method of delivering the feed from the feed-box, which was invented by Mr. Swanwick, an inge- nious teacher of writing and arithmetic, with fome branches of na- tural philofophy, in Derby; and who will not be averfe to fhew the working models of the feed-boxes, or to give affifance to any one, who wifhes to conftruét either this drill machine, or the pre- ceding one:
