"Is it cheaper than this would be," Tyrrel asked, for Le Neve had laid stress on the point that for economy of material, combined with strength of weight-resisting power, his own plan was remarkable. "Cheaper!" Sir Edward echoed. "Oh dear, no. By no means. Nothing could very well be cheaper than this. There's genius in its construction, don't you see? It's a new idea, intelligently applied to the peculiarities and difficulties of a very unusual position, taking advantage most ingeniously of the natural support afforded by the rock and the inequalities of the situation; I should say your friend is well within the mark in the estimate he gives." He drummed his finger and calculated mentally. "It'd save the company from a hundred and fifty to two hundred thousand pounds, I fancy," he said, ruminating, after a minute. "And do you mean to tell me," Tyrrel exclaimed, taken aback, "men of business like the directors of the Great North Midland will fling away two hundred thousand pounds of the shareholder's money as if it were dirt, by accepting Walker's plan when they might accept this one?" Sir Edward opened his palms, like a Frenchman, in front of him. It was a trick he had picked up on foreign bourses. "My dear fellow," he answered, compassionately, "directors are men, and to err is human. These great North Midland people are mere flesh and blood, and none of them very brilliant. They know Walker, and they'll be largely guided by Walker's advice in the matter. If he saw his way to make more out of contracting for carrying out somebody else's design, no doubt he'd do it. But failing that, he'll palm his own off upon them, and Stillingfleet'll accept it. You see with how little wisdom the railways of the world are governed! People think, if they get Walker to do a thing for them, they shift the responsibility upon Walker's shoulders. And knowing nothing themselves, they feel that's a great point; it saves them trouble and salves their consciences." A new idea seemed to cross Tyrrel's mind. He leant forward suddenly. "But as to safety," he asked, with some anxiety, "viewed as a matter of life and death, I mean? Which of these two viaducts is likely to last longest, to be freest from danger, to give rise in the end to least and fewest accidents?" "Why, your friend Le Neve's, of course," the millionaire answered, without a moment's hesitation. "You think so?"
