It is one of the few bright lines in this picture that whenever the people got a chance to make themselves heard, their utterance was always right and true. The four juries which passed upon the facts understood them, and had the moral standard by which to judge them aright. One of the trust's employés was put on the stand to break the effect of the evidence that the competition of the new works had put down the price of oil. "In the early part of 1881--the winter of 1881"--he said, "common oil was 5-1/2 cents a gallon"--this to prove that the reduction had preceded the appearance of the new refinery. He was confronted by the District Attorney with one of his own bills of oil sold in February, 1881. "That would seem to be a sale of 120 degrees oil at 12 cents a gallon," he confessed, and added, awkwardly, "I was asked as to the winter of 1881. That is not the winter of 1881 as I understand. I meant to speak from July, 1881, and so on."[500] The great lawyers held up to the ridicule of the jury the idea that the gases of distilling petroleum were dangerous. Matthews stated on the stand that he had seen this gas burn up derricks, property, and several men. The lawyers could not let anything so absurd go unchallenged. "Did it explode?" he was asked smartly. "Yes, sir." "And how did the 'explosion' burn up the men and property?" with a knowing look to the jury. "The gases crept quietly to the boilers, unobserved," said the witness, "and all at once the whole atmosphere was ablaze." The witnesses who tried to prove that no harm could have resulted from the tampering with the still broke down. One of them was the inspector of oils at the combination's refinery at Cleveland. He, too, had once been an independent refiner, but had passed under the yoke. He declared with every possible variation of phrase that there could not have been an explosion at the Buffalo works; but the District Attorney got out of him piecemeal admissions that the "escaping petroleum gases would be inflammable"; that "in a damp day you would expect them to settle close to the still"; that then, if they came in contact with fire, "you would have a large flash, and consume those vapors; if a person was in the vicinity he would burn." "I ask you if it would be a safe thing to fill a still with 175 barrels of petroleum, put under it an extremely hot fire, so that the front portion of the still is a cherry red, and a weighted safety-valve is blown off--would you consider that a safe thing to do?" "I would not."
