The "Golden Age of Agriculture". The incomes of farms doubled and the value tripled. Between 1898 and 1915 the amount of wheat planted in North Dakota more than doubled from 4,300,000 acres to 9,400,000 acres and production grew from 69 million bushels to 159 million bushels. The increased use of machinery, ever larger and more powerful, was the key to the farmers' success.
