Silas Saylor is one of the pioneers of Deerfield, one of the few whom Father Time has seen fit to leave as a relic of a generation that has gone. In the picture gallery of his memory he is still able to discern a faded representation of Deerfield as it was sixty-eight years ago. In October of 1818 he came into the township with his parents, his sister and a brother-in-law, Benjamin Weimer. At this time, he says, Deerfield was almost a wilderness; a few hardy settlers had made "little holes in the forest" in which to construct their cabins. A man by the name of James Reed had a little distillery, which kept the pioneers supplied with what was then considered a necessity for those who were exposed to the vicissitudes of the weather, and an indispensable article to those engaged in the performance of severe labor. Reed also had a handmill, which was patronized by the settlers in the immediate vicinity. John Price was the blacksmith ; lie sharpened the plowshares, welded the logchains and shod the horses of those wealthy settlers who could boast of the possession of these valuable animals.
