T h r tunnel and dust rnmplrng equipment has been described previously ( 3 ) . Opcrntionnl techniques and the calibration of the tunnel to permit the control or determination of the several variables involved in field use were developed in the laboratory. These procedures also have been described ( 4 ) . Field use of the equipment and techniques was first made in November 1949. The results serve to demonstrate the possibilities and limitations of thr approach. While the data at hand ttre limited, they throw considerable light on the interrclationships of the many factors governing the stability of field surfaces to the erosive forces of wind. Plot G-1-4.-Sorghum rrubble /ron~iuuour).-Planted continuously to grain sorghum since 1942. Grain was =omb i n d in the fall of 1949 nt a height of about 20 inches. Thc plut is always left until the spring before any tillage is performed. All plantingr are made with a lister in 4Winch rows. Either one.way disking o r blank-listing comprises the tillage, depending on the nrmmnt of sorghum residue remaining on the plot.
