Sept. 15 -- Sept. 15 – On this day in Montana history in 1910 The Newspaper of Chester published what it called the “Ten New Dry Landers’ Commandments” on its front page.  Among them was “thou shalt plow deep,” “thou shalt summer fallow when rainfall is less than 15 inches,” “thou shalt add organic matter to the soil.” The list ended with “he who obeys these commandments shall reap abundant crops.”
