It was the elderly President Rogers of Manhattan University who brought the thing to a focus. He and the university's other officials had been growing more and more restive under the criticisms that Grant's controversy was bringing on the school, and so at last he suggested that a meeting be held at which Grant could lay his theories and data before his fellow-scientists in their entirety. This Grant accepted, and so too did most biologists of any note within traveling distance of New York, so widely had the clamor of the dispute spread. And on an afternoon Grant rose before several hundred assembled scientists in one of the university's lecture-halls to explain his discovery. There is little need for me to tell at length of what took place at that meeting, which both Ferson and I attended. At the first appearance of Dr. Grant his enemies in the audience grew vocal in their criticisms, and before he had spoken a quarter of an hour the hall was in such an uproar as a scientific meeting has seldom heard. Twice Grant made an effort to go on and each time his voice was drowned by a storm of shouted cries. The President, chairman of the meeting, was rapping vainly for order, but Grant only stood still, looking out over the stormy meeting with a cold contempt in his eyes, yet with a strange fire in them. Quietly he rolled up the data-sheets in his hand and thrust them into his pocket, and as quietly stepped forward to the platform's edge. Something in his bearing, in his expression, quickly quieted the noisy throng before him. His voice came out over the hall cold and clear. "You have not let me give to you the proof for which you asked," he said. The President stepped to his side, said something rapidly, but Grant shook his head calmly. "No proof that I can give you here would convince you of my theory's truth, I know," he told the silent throng before him, "but I will give you proof of it yet! To you, and to the world, I will give a proof such as the world has never seen before!" Before any could move, he had walked from the platform and out of the hall. A buzz of excited voices broke out instantly, in comment and criticism. It was some hours later before Ferson and I got from the meeting to Grant's laboratory. But Grant was not there.
