Trevannion stared at him. The laugh, the jeer, that had risen in his heart at this sudden failure of nerve never found expression. There was something in the young fellow's face that spoke of more than a qualm of nervousness. It was a pitiful terror that met Trevannion's eyes—the pleading terror of a dumb, helpless animal before a human tormentor.
For a moment the engineer stood irresolute. Two men, engaged in mixing cement a few yards distant, had laid down their spades, and, having heard Trevannion's invitation to cross the beam, were looking at "the new bloke" in mild wonder as to why he hesitated. A third was slowly trundling a wheelbarrow full of sand towards them. Trevannion took in these details in a flash—and realised their significance. Here was an easy chance of shaming Garstin before the gang, of convicting him of rank and unprofessional cowardice, of getting his own back again from the office-desk theoretician, yet—an uncontrollable impulse of generosity prevented his seizing it. He stepped on to the bank and stood beside the fear-struck figure.
"You must come on," he said in a whisper that was little more than a breath. "Pull yourself together. I'll hold you."
An instant later, and for an instant only, the two stood together on the narrow beam, Garstin a shrinking form, his every limb shaken by something more potent than the gusty wind, his face turned anywhere but downwards. Trevannion did not hold him, but his hand rested reassuringly on the other's quivering arm. For an instant only, and then Garstin was pushed on to the firm bank again and hurried towards the office.
Trevannion talked jerkily as soon as they were out of earshot of the gang. "Sudden attack of funk—rather a bogie place on a slippery day—might happen to anybody—get used to it—dance a jig on top of the king pile one day, and wonder how you could ever have been such a——"
"Coward," finished Garstin quietly.
"No-o, that's not exactly the word," said Trevannion lamely, and waited for explanation or extenuation.
But none came. It was as if the boy was quite aware of the cowardice, and did not wish his companion to consider it anything else. Trevannion's mind marvelled at the seeming abasement.
A few days later Trevannion reported progress to his wife anent the new assistant, whom for some strange reason he had grown positively to like.
