Comni enting on the debate in the senate over the duty on tin plate The Evening Post saya, after adinitting by direct implicaton the assertion of The American Economist that the provisión of the Mills bill taking the present duty off from tin plate was aimed at our sheet iron industry: "They have somehow got hold of the Republican machine - probably by contributions to the campaign fund." This is from a paper which never mentions the contribution of $50,000 made to the Democratie campaign fund by an agent of the North Germán Lloyds, nor the remarkable extensión of that company's earnings for carrying the United States mails under the late Democratie administration. But there are undoubtedly very heavy financial contribntions available to the opponents of an increased duty on tin píate. They do not, however, come from American manufacturera, fof if they did we would miss the active interest displayed by The Post in this subject. According to the speeches at the Llanelly water works meeihg, held June 3 last, where "the principal topic of discussion was the McKinley tariff bill, and the probabilities of the clauses increasing the duty on tin plate being agreed to in the senate," the prosperity of the Welsh tin plate makers dependa on beating those clauses. Mr. Tregoning summing up the situation said: "Their destiny, however, was not in their own hands; it was in the hands of the congress at Washington. He might be looked upon in this matter as pessimistic, but there was no doubt that something was going on in the United States which, if carried out, would mean not only a 'stop week,' but a perpetual 'stop week' so far as a great many of the tin plate works in that neighborhood were concerned." Mr. Rokers, another maimfacturer, in saying "the time would come when America would manufacture her own tin plate," recognized the fact that all Americana could not be fooled all the time, and that thereis not money enough available in England to continue this country in its present wasteful practice of paying $33,000,000 ayear to foreigners for an article we can inake onrselves with American labor and American material. All European manuf acturers will find their profits decreased by the McKinley bill, for they will have to continue selling goods at about the old price, after payiug increased duties, untü new milis are started in this country, when they will have to sell for a lesa price.
