Birdsill Holly's first hydrant, patented in 1869, is my favorite hydrant design. The wood is oak, most likely emory oak because of where it was found. It was a burl in a friend's backyard for many years, where it seems it just got harder and harder. Much of the work on this had to be done with carbide cutters. The burl was heavily cracked, so after turning the initial cylinder, I cast it in resin with a red tint to fill the cracks.
