This paper presents the results of a study to throw light on various problems relating to the spread of black locust (Robinia pseudacacia L.) on southeastern Ohio farmlands. Planting for erosion control, begun many years ago, has been followed by a spread through root suckering at rates varying with local conditions of site and land use between 3.3 and 10 feet a year. The advance was slowest on lands heavily grazed. By planting a square 2 1/2-acre worn-out field or pasture either in 5 parallel strips or in 8 groups, a 6-foot annual advance would obtain a complete coverage in from 7 to 10 years, with a large economy in cost and quantity of planting stock.
