History of the beet sugar industry: The production of sugar from beets is a new industry when compared with the length of time that most kinds of crops have been used by man. It was only about 150 years ago that sugar was extracted from beets even in the laboratory, and at that time the percentage of sugar was so low that the expense of extracting was more than the sugar was worth. Just a little more than 100 years ago the first beet sugar factories were built, but it was nearly fifty years after this time before the industry became thoroughly established in Europe. In the United States an attempt was made to manufacture beet sugar as early as 1830, but practically nothing was done till in the seventies. Since that time growth has been somewhat irregular, but at present there are about sixty-six factories operating in this country.
