Plate vn. top. Tlie Reiley plow cuts salt-marsh ditches ten inches wide with 

 vertical banks, depth being variable to a maximum of thirty inches. The 

 ditch shown here is eighteen inches deep. The cut sod is deposited as a con- 

 tinuous ribbon, bottom. This special machine developed by the New Jersey 

 Agricultural Experiment Station can cut new ditches or recut those in need 

 of maintenance. A continuous chain of excavating buckets, operating at high 

 speed, grinds up the sod as the ditch is dug.
