380. Crop Meter, about 1925. USNM 283306; 1969. This crop meter was
developed in 1925 by the Department of Agriculture as an aid in
estimating the acreage of cotton in Mississippi. The crop meter was
attached to the dashboard of an automobile and connected by cable to the
odometer. 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

with an indelible pencil. The original paper and copy papers were placed
between two water-soaked linen leaves and all was rolled up on a wooden

minutes until the penciled ink stained through the wet papers and thus
made copies. This specimen was used on a farm in Virginia. Gift of Mrs.
