By 1868, Andrew owned securities and partnership shares worth ever $400,000 and was receiving payment of over $55,000 a year. Carnegie was becoming a successful capitalist and would continue getting richer. Andrew would use the money he made through capital to invest in other businesses. For instance, he would use money from Woodruff to then invest and buy Columbia Oil Company. Carnegie and his partner would attempt to hoard the oil produced and influence the price and the stock. Their plan would end up not working out, and instead they would become efficient producers, and finally Carnegie decided he didn't have a taste for the oil business and would sell Columbia Oil. With the sale of Columbia Oil, Carnegie then invests in the Keystone Bridge Company. Carnegie would eventually leave the railroad industry because he had an incredible business sense and could foresee major railroad construction in the near future and wanted to secure work for Keystone. As the years entered into the late 1860's, Carnegie would find ways to manipulate Western Union and Pacific Union stock and would make vast amounts of money from these practices. Carnegie by this time, would focus almost completely on investments. He and his partners came up with an idea to make profit from the booming telegraphy industry. Carnegie would promote the benefit of cooperating rail lines and telegraph lines through franchising. Pacific and Atlantic telegraph would eventually offer to buy 1000 shares of Carnegie's Keystone Telegraph Company, and thus giving one third of Pacific to him. Carnegie would then promote expansion by bartering his Pacific stock with that of construction costs. Then once the dividends would stop Carnegie would immediately plan to get out of the company, selling stock at maximum price and letting the rest of the Pacific stockholders to get burned by the lowering of stock price. This would be a common theme of Carnegie's burning desire to succeed without the care for other parties as well as his innovative business mindset.
