When the Senate showed a disposition to resent his interference, Blaine addressed to Senator Frye of Maine a letter which was in effect an appeal to the people, and which greatly stirred the farmers by its statement that "there is not a section or a line in the entire bill that will open the market for another bushel of wheat or another barrel of pork." The effect was so marked that the Senate yielded, and the Tariff Bill, as finally enacted, gave the President power to impose certain duties on sugar, molasses, coffee, tea, and hides imported from any country imposing on American goods duties, which, in the opinion of the President, were "reciprocally unequal and unreasonable." This more equitable result is to be ascribed wholly to Blaine's energetic and capable leadership.
Pending the passage of the Tariff Bill, the Senate had been wrestling with the trust problem which was making a mockery of a favorite theory of the Republicans.

They had held that tariff protection benefited the consumer by the stimulus which it gave to home production and by ensuring a supply of articles on as cheap terms as American labor could afford.

There were, however, notorious facts showing that certain corporations had taken advantage of the situation to impose high prices, especially upon the American consumer.

It was a campaign taunt that the tariff held the people down while the trusts went through their pockets, and to this charge the Republicans found it difficult to make a satisfactory reply.
The existence of such economic injustice was continually urged in support of popular demands for the control of corporations by the Government.

Though the Republican leaders were much averse to providing such control, they found inaction so dangerous that on January 14, 1890, Senator John Sherman reported from the Finance Committee a vague but peremptory statute to make trade competition compulsory.
