      � Soon the whistle sounded, the great train rolled into the station, the conductor shouted "All aboard!" our friends took their seats, the bell rang, and the locomotive coughed asthmatically as it moved on. � His son's attitude exasperated him. "You know this ain't ever been our way; you'd say so, yourself, ef you wa'n't skin full o' china-ball whiskey! What in all hell is the reason we can't do him as we've always done the others?" "My son? Oh, he's in Virginia, with General Lee." � "drop back into the ranks," said Quinn to him. "Smith, ride on to Lieutenant Ferry. Corporal,"--to a man near him--"you know the way so well, go with him." � And then he stopped abruptly, aware of a cool sensation on the top of his head. His hat and wig had gone! Aghast, he retraced his steps, but there was no sign of the articles on the pavement. It seemed utterly incredible, for there was only a slight breeze and he did not remember knocking into anything. He had certainly not collided with the stranger. Just for a moment he wondered. "Did you speak to the Spanish woman?" he asked. "Well, fortune was kind to me. I couldn't think what that blacklead was doing there." Considering material progress as consisting primarily in the demonstration of scientific truths, and secondly, in their application to useful purposes, we can see the position of the engineer as an agent in this great work of reconstruction now going on around us. The position is a proud one, but not to be attained except at the expense of great effort, and a denial of everything that may interfere with the acquirement of knowledge during apprenticeship and the study which must follow. The mechanical engineer deals mainly with the natural forces, and their application to the conversion of material and transport. His calling involves arduous duties; he is brought in contact with what is rough and repulsive, as well as what is scientific and refined. He must include grease, dirt, manual labour, undesirable associations, and danger with apprenticeship, or else be content to remain without thoroughly understanding his profession. � � I. � � � � � � The Recruits Lined up on the Platform. 186 "Sir, I congratulate you. That was splendidly done. I was just getting on to that fellow when you went down. I watched you through my glass, and saw you fetch him. You are entitled to all our thanks." � "You kin go, sir, and report to them people that it won't be did," answered Si firmly. � "And the eyes of the sleepers waxed deadly and chill, And their hearts but once heaved, and forever grew still," continued Monty. � Reuben was glad to escape into his farm work. The atmosphere of sickness was like a cloud, which grew blacker and blacker the nearer one came to its heart. Its heart was that little room in the gable, where he spent those wretched nights, disturbed by Harry's moaning. Out of doors, in the yard or the cowshed or the stable, he breathed a cleaner atmosphere. The heaviness, the vague remorse, grew lighter. And strange to say, out on Boarzell, which was the cause of his trouble, they grew lightest of all. � Reuben crept out of his thorn cavern and looked down the slope. At the bottom by Socknersh one or two lanterns moved through the dusk. He stiffly threw up his arm and tried to shout. His throat felt cramped and swollen, and it was not till after one or two attempts that a sound pitifully like a bleat came out of it. A voice answered him from the hollow, and then he saw that they were carrying something. He limped painfully down to them. Richard, Boorman, and Handshut carried a hurdle between them, and on the hurdle lay a draggled boy, whose clenched hand clutched a tuft of earth and grass as a victim might clutch a handful of his murderer's hair. � It was David who drew William's attention to the woman sitting at the other end of their seat. David piqued himself on his knowledge of the world. "It's our chance," said Bill. � � � But this burst of indignation soon passed away, and upon the suggestion of the prudent Sir Robert Hailes, he sent an evasive answer, with a command that the Commons should attend him at Windsor on the Sunday following.
