foot-yard
In Pennsylvania, a miner's measurement of length, such as the distance a working face is advanced. With the heel of one foot on a mark, a short step is taken and the tip of the forward toe marks the foot-yard. The next measurement is taken by placing the first foot against the toe of the second and repeating the first step and so on. The foreperson checks measurements with a rule.
