"Speculation in oil stock companies was another great evil ... From the first, oil men had to contend with wild fluctuations in the price of oil. ... Such fluctuations were the natural element of the speculator, and he came early, buying in quantities and holding in storage tanks for higher prices. If enough oil was held, or if the production fell off, up went the price, only to be knocked down by the throwing of great quantities of stocks on the market."
