Maples on a steep hillside can be piped with plastic tubing (coils on shoulders of crew) to a main plastic line (black tubing feeding into gathering tank). Gravity thus eliminates hanging and emptying sap buckets. One worker holds a red, gasoline powered tree tapping drill. C18020 Mike Roberts BERKELEY CALIF.
