Traditional methods of sap collection have changed over time. Initially, Native Americans created gashes in the stem, and directed sap into wooden or bark vessels. Early spouts were created by hollowing out small twigs, which were inserted into tapholes created with a hammer and chisel. Sap flowed into wooden buckets placed on the ground. Later, a bit and brace were used to produce the taphole, and mass-produced cast or rolled metal spouts were employed to both direct sap into wooden, then later metal buckets, and to hold the bucket above the ground.
