Marietta Hall sent this photo that she entitled "Art in the Meadow.”

"After a lush green pasture had just been mowed, I thought the lines of grass presented a majestic and unique pattern of waves that were left by the brush hog on the tractor that my husband drove as he followed the lay of the land long the slope," she said.

Hall also sent this photo that she sent, "purely because I see the beauty in the form of the fence."

"This is a fence along our back pasture as it gracefully curves along the slope of a hill down to the meadow," Hall said. "It leads one’s eye right up to a lovely stand of bright, fall foliage. The horses had just moved off grazing this area when we came along."

Both were taken at the Hall's Dogwood Hill Farm in Unionville, Pa.
