Mark Peper, 21, cuts a qing chestnut while preparing to graft another chestnut plant to the top at MU's Horticulture and Agroforestry Research Center on May 30. The process is similar to grafting bur oak trees.

Chestnut saplings sit on the ground after being grafted. Aluminum foil is wrapped around the graft to regulate the temperature around the cut.

Mark Coggeshall, a research analyst at MU's Horticulture and Agroforestry Research Center, demonstrates grafting part of a bur oak onto another bur oak on May 30. Although Coggeshall is not grafting wood from McBaine's champion bur oak, the process is the same.

From left, Brian Flatt, 36, Jadon Flatt, 9, and Ron Flatt, 60, stand in a corn field on their farm in Audrain County on May 30. Because of an unusually wet season, only 70 percent of their corn crop has been planted. Ideally, all of the corn would have been planted by late April and the stalks would be about waist-high by now.

The corn in this Audrain County field is unusually small for this time of year. The plants visible are weeds, which tower over the inch-tall corn plants.
