The "united refiners," to explain away the faults of their oil, sent a representative to the congress who was one of the inspectors of the State of New York, in the pay of the people, but using his official prestige in behalf of a private interest. The consul at Bremen names the two chief points made in the defence: First, that the refined oil was bad because half the crude then produced in America was from the Bradford field, "and is so different in quality from the so-called Parker oil that the same quality of refined oil cannot be made--at any rate, by the ordinary processes hitherto in use." Second, that the wicks in common use were poor. That the inferior quality of the Bradford oil was not the real reason was proved by the fact that the refined oil manufactured and exported by the refineries of the combination from the crude of the other fields deteriorated at the same time and as much.[592] The Bremen congress knew this. It was at this precise moment--though this the Bremen congress did not know--that the combination was tying up a great inventor and hauling his apparatus to the junk-yard to prevent the test of a new method for making better and cheaper oil.[593] Its members would have had the benefit of it if successful, but with the spirit which men who seek exclusive control always exhibit, they did not want to change. The congress declined to treat with any respect the excuses that were offered. It declared "that the complaints regarding the inferior quality of much of the petroleum recently received from America, and especially of the different brands of the" oil combination, were "fully justified." It consequently demanded from the American refiners, and especially from the oil combination, "First, that they give greater care to the refining of crude oil than they have recently done, in order that the petroleum may in the future be again as free as it formerly was from acids and heavy oils, that inferior qualities may no longer be shipped to Europe, and that the consumer may again receive the former customary good quality."
