This is the third internal combustion tractor made by Hart-Parr around 1903, and it is part of 'The Changing American Farm' exhibition at the Smithsonian's National Museum of American History until November 1. Photograph courtesy of the National Museum of American History.

The role of machinery in farm progress is shown very effectively in an exhibit on The Changing American Farm, on view in Washington, D.C., through November 1.

Visitors can see very early implements, such as the John Deere 'singing plow' of 1837 and a Texas cotton planter of the 1840s, as well as more modern engines which brought one breakthrough after another in increasing productivity.

The show was made possible by a grant from International Harvester, to commemorate the 150th anniversary of Cyrus McCormick's invention of the reaper in 1831.

John T. Schlebecker, well known to many of our readers as an outstanding authority in this field, served as curator for the exhibit, which is at the National Museum of American History, part of the Smithsonian Institution.

Schlebecker, a native of Montana, also wrote the catalog, in itself a work of art that we think our readers would treasure.
