The next day Glen did not feel like meeting any of his young companions. He wanted to think over the several problems that had been presented to him. So he wandered down to the river, where a fine new railroad-bridge, in the building of which he had been greatly interested, was now receiving its finishing touches. As he walked out towards the centre of the graceful structure, admiring, as he had a hundred times before, the details of its construction, its evident strength and airy lightness, he saw the engineer who had charge of the work standing, with a roll of plans under his arm, talking with one of the foremen.
