3. _Competition of less capable producers works in most cases to prevent the great or continued rise of trust prices._ Early trusts overestimated their power. The persistence of competition in industries where the trusts have had great advantages in position and resources has been astonishing. The wall-paper trust, though for many years it kept prices above competitive rates, was repeatedly undermined by competition. The whisky trust, while it frequently raised prices, was as often forced by the growth of small distilleries to lower them below competitive rates. Competition in the oil industry has persisted under the greatest difficulties. The smaller companies have hauled the product by wagon when the trust was moving it by pipe-lines. The continuance of high prices by a trust depends on a high degree of control of supply. A recognition of the limits of their power has led trusts in some cases to a policy of moderate prices, affording a good profit, but not encouraging competition. [Sidenote: Supply as the condition of low prices] The limits of the power of the trust to control prices are strikingly shown by the fact that it cannot even insure low prices if the market conditions do not justify them. The steel trust, in 1902-3, declared that it would not advance the price of steel rails above twenty-eight dollars, and this was hailed as a beneficent effect of trust control, which, by equalizing production, could prevent excessive fluctuations of price. But the trust's declaration was a bit of inexpensive humor on the part of the managers; the trust had nothing to sell at the price quoted, as its entire product had been sold out months in advance. While, therefore, the trust continued calmly to quote steel rails at twenty-eight dollars, competition raised the market price to thirty-three dollars a ton; twenty-eight dollars or more was paid for second-hand rails, and a proportionate price for other iron products. Such exceptional conditions, raising prices to abnormal levels, are followed by a decline disastrous not only to the small producer, but to the trusts as well. [Sidenote: Modes of controlling trusts]
