Every month I choose a photograph from one of my Flickr groups to appear here. Hopefully something interesting and informative.
This month's photo is from our regular contributor, Judo Dad It's called "Cord". It shows a pile of firewood.
The text accompanying the photograph reads, "The cord is a unit of dry volume used in Canada and in the United States to measure firewood. One cord is defined as 128 cubic feet (3.62 m³), corresponding to a woodpile 4 foot wide × 4 foot high × 8 foot long. In the United States, the cord is defined by statute in most states. In the metric system, wood is usually measured in steres or cubic metres: 1 stere = 1 m³ ≈ 0.276 cords.
Another measure of wood volume is the sheldon cord (sometimes called a long cord), which usually does not have a legal definition, and its size varies regionally but is always larger than the regular cord.
Other non legal definitions of firewood volume include standing cord, kitchen cord, running cord, face cord, fencing cord, and country cord. According to the Weights and Measures Act in Canada, the only true definable cord is a full cord and all other fractions thereof. "
