Read it through once

Thirty flouring-mills turn out two million barrels of the very choicest of flour every year; twenty sawmills produce two hundred million feet of lumber annually; then there are woolen mills, cotton mills, paper and oil mills; and sash, nail, furniture, barrel, and other factories, without number, so to speak. The great flouring-mills here and at St. Paul use the 'new process' and mash the wheat by rolling, instead of grinding it.
