<P> In 1904, James Jerome Hill, president of and the largest stockholder in the Great Northern Railway, won the financial support of J.P. Morgan and attempted to take over the Chicago, Burlington and Quincy Railroad (CB&Q). The Burlington served a traffic - rich region of the Midwest and Great Plains, was well - managed, and quite profitable . It possessed a finely - engineered line connecting the Twin Cities to the nation's rail center of Chicago, which made it particularly attractive as an addition to Hill's Great Northern . </P> <P> Hill's strategy was for his railroad and Morgan's Northern Pacific Railway to jointly buy the CB&Q .

Harriman then began to buy up Northern Pacific's stock, forcing Hill and Morgan to counter by purchasing more stock as well . Northern Pacific's stock price skyrocketed, and the artificially high stock threatened to cause a crash on the New York Stock Exchange . Hill and Morgan were ultimately successful in obtaining more Northern Pacific stock than Harriman and won control of not only the Northern Pacific but also the Chicago, Burlington and Quincy . </P> <P> Pressured by Harriman's actions, Hill created a holding company--the Northern Securities Company--to control all three of the railroads .

Justices Day, Brown, McKenna and Brewer concurred . </P>
