Full Text
The Germans now add ammonia to the waste liquors of breweries or sugar factories, and produce food protein directly with the aid of yeast.
Reports also come on high authority that in Germany artificially digested wood fiber is being used in stock-feeding. Wood is chemically closely related to starch and sugars, and the making of sugar out of cellulose has been done experimentally in the laboratory for a generation. It was only a question of getting the process cheap enough to be practical, and we who would scoff at "bread from sawdust" may be regarded by our children as old fogies, akin to those who refused to believe in airplanes and wireless telegraphy.
