I believe the answer is Wheat farming, i hope this helped
The history of the bonanza
farm started with the arrival of the railroad, as with the history of America’s
westward expansion. A group of entrepreneurs dreamed of building a railroad
across the northern territory to the Pacific Ocean during the mid-1860s. The
newly-formed Northern Pacific Railroad began construction with financing from
Jay Cooke and his banking institution, as well as the millions of acres in
government land grants. Entering present-day North Dakota., the NP has
traversed the Red River by 1872.
<span>The NP and the entire
country was in a financial panic since Jay Cooke went bankrupt a year later. The
NP allowed stockholders, who were holding deflated stock, to purchase huge
tracts of land at a cost comparable with land sold by the government, in order
to raise money that was needed to continue the railroads construction.</span>
<span>Jefferson pointed out that the constitution granted the president the power to purchase lands as needed for the country. His statement was that this case was similar to that of a legal guardian who invested money of his ward to purchase important adjacent territory then telling him he did this for his own good and he will gain it and appreciate it when he comes of age.</span>
