We fancy that many of our readers will protest and say that there are scores of plants in America making alcohol from wood. But they would be mistaken. The plants to which they refer are making wood alcohol, which is not alcohol at all. It simply resembles alcohol in color, slightly in odor, and in the fact that it will burn, though with no such heat as results from the combustion of genuine alcohol. A better and more descriptive name is " wood spirits," which is used in France. Scientifically it is know as methyl alcohol, while real alcohol made by the fermentation of sugar is ethyl alcohol. Without attempting to be too technical, the chemical formulae of these two commercial products may be of value- Ethyl or "grain" alcohol is This maens that a molecule of alcohol is made up of two atoms of carbon, six of hydro- gen and one of oxygen. The formula for methyl or wood alcohol is CH4G\ That is, it has one less atom of carbon and two less of hydrogen. Grain alcohol is com- paratively innocuous, while wood alcohol is a virulent poison. Cases are numerous where people have wood alcohol because they supposed it to be alcohol, and have promptly Wood alcohol has a large place in the arts, but grain alcohol has all the virtues of wood alcohol and many other besides. To make real alcohol out of wood is from a practical standpoint a new thing. It has long been a fact well known to chemists that theo- retically it' should be possible to make alcohol from wood, for wood contains cellu'ose, and cellulose can be converted into sugar, and from sugar by fermen- tation is made
