Stereo is a measure to measure wood and wood. Yes, like wood, wood. Some see wood as the wood in the tree. In a small town in Navarre I learned that lesson very well, I think in the Sakana. Wood is the right part for materials and the part that does not serve the materials is wood. The material shall be used for woodworking and carpentry operations. Wood for stakes, mangoes, fire, etc. Each of the hogueras has their cheats and their katramiles. It is not the same to heat the bread oven, burn the limestone in the cale, cook the wood in the mat, burn apples or put the puchero in the manure, burn the chestnut on fire the cyclist or the tamber, or the cumulative heat of the must (Quercus cifera).

In the stereo, the measurement consists of measuring logs, knots and horns in crude. When the trees and trees collapse, the stereo is the one that accumulates in its roundness all the muscles, fat and cortices, as dense as possible, and fills the cubic meter. The stereo name comes from the Greek word σ≥ ρν????????? And it means "compact." Stereo is used in places where wood and wood are not very cultivated: on the mountain, in the forest, in the trucks, in the paper factory, in the sawmill... Then work will be done: peel the skin, take off the coast, start and make the beams. In the carpentry or in the carpentry or in the construction that use them we will not listen to the word stereo immediately, nor what to say about the woodworking... The thinner the wood, the further away the stereo, as if the delicacy and consistency were incompatible... That is why it is not approved in the International System of Units or in the Metric System?
