Mike Wiemann, a botanist in the Forest Products Laboratory’s (FPL) Center for Wood Anatomy Research, has a special skill: identifying wood species, often with just a quick look through a tiny hand lens he carries in his pocket.

While most of us simply see wood, Wiemann can recognize varying species by looking at the end grain and evaluating the size and arrangement of the tissue components. And he did just that recently for a visitor to the Lab with a unique collection.
Willis Parker, a retired veterinarian, has an extensive collection of hames, two curved pieces of iron or wood forming (or attached to) the collar of a draft horse. Parker has collected nearly 400 hames over several decades, and is working to clean, photograph, identify wood species, and name the makers to preserve the history of their use.

Interestingly, Wiemann happened to know what a hame was thanks to his college days. “In 1964, a requirement of the Intro to Forestry class I took my freshman year was to memorize and identify the parts of a harness,” said Wiemann. “I never thought I’d use that information again!”
With special permission from Wiemann (whose skills are in high demand), Parker brought 22 hames to FPL one sunny afternoon for wood identification. Some were well-worn and simple in design, used for work horses that pulled plows; others were painted and ornate, used when pulling carriages for wealthy passengers.
Parker laid out the pieces of wood, most dating from the early 1900s, and Wiemann got to work. What he found were hames made from ash, beech, red oak, white oak, hard maple, and elm.

Parker carefully tagged and labeled each hame after Wiemann announced the species, and he thanked Wiemann repeatedly for helping gather such useful information about his collection.
Wiemann was more than happy to help, as here at FPL, public service really is all in a day’s work.
