This photograph by Harris & Ewing shows President Woodrow Wilson's sheep grazing on the South Lawn. Instead of using groundskeepers to cut the grass, the sheep grazed on the White House lawns. The flock grew to 48 at its peak. The wool sheared from the sheep was sold at auction to raise money for the Red Cross.
