A circuitous route was followed through the cotton area, and when the driver came to the edge of a cotton field he pushed a button which started the meter measuring the frontage of the field. The total mileage registered could be interpreted in terms of the acreage. The meter method was later replaced by aerial observation. Gift of Statistical Reporting Service, U. S.
