This drawing is from the Ross Farm Story by J. Lynton Martin,
published by the Nova Scotia Museum in 1974.
The inventory of Thomas Richardson's possessions, made in 1829, tells us that he owned a plough but does not indicate what type of plough it was. When John Young wrote Letters of Agricola in 1818, in an effort to improve agriculture in Nova Scotia, he recommended the type of of plough you see here as the best available.
A plough made it possible to turn up the soil to make a seed bed for growing crops.
