Promoting Agriculture, on the subjects of potato cultivation (1785); sowing wheat in clumps (1785); treading out wheat (1786);
description of Bordley's cluster drill for wheat with drawings of the apparatus (1786); fattening hogs (1786); scarcity of
timber (1787); malt and beer (1787); use of ammonia (1787); John Singleton's method of sowing wheat on clover (1787); and

Two of these items are addressed to Samuel Powel, president of the Society. At this time Bordley farmed on Wye Island on
the eastern shore of the Chesapeake Bay, he describes farming practices in Kent County and Talbot County, Maryland.
