The case had an immediate hearing, and after three days' trial the Circuit Court decided unequivocally that the plow now in general use over the country was unlike any other which had been produced ; that the improvements which rendered it so effective were due to Jethro Wood, and that all manufacturers must pay his heirs for the privilege of making it.
