These spouts are rather like modified pieces of pipe from which the bucket is hung or pipeline is run. A cover keeps dirt and rain water out of the buckets until collection; pipeline carries the sap directly from the tree to the storage tank. in Farm Tours Portville Login to post comments Email this page Travel Guide It's a full 56-page comprehensive guide, highlighting the activities and attractions in our County and it's FREE!!
