“Well, I guess it’s good-bye, Helena,” said Bob, while Ned and Jerry were bidding farewell to some boy and girl friends, among them Mollie Horton and Alice Vines. “Yes, good-bye,” Helena murmured. “I’m sorry you’re going, but I suppose you know your own business best. Perhaps you will not be gone for as long as you think.” “Oh, I guess it will be for a long time,” said Bob. “This war isn’t going to be over in a hurry. But we’ve all got to do our duty.” “Well, it’s too bad we can’t all have the same duty,” sighed Helena. “However, I suppose that can never be. Good-bye, Bob. Write to me when you get a chance!” and before Bob knew what was happening she had given him a rather sisterly kiss on his forehead and disappeared in the crowd. “Here! Wait a minute!” called Bob, starting after her. But the train came in just then and there was so much confusion, and such a scramble to get baggage together and find places in the cars, that Bob did not get another glimpse of Helena. A United States regular, Sergeant Mandell, was in charge of the recruits, having been detailed by Lieutenant Riker to conduct them safely to Camp Dixton. “All aboard, boys!” he called. “All aboard!” “All aboard she is!” echoed Jerry. “We’re off for the camp!” said Ned. Bob said nothing, but as soon as he got in his seat he raised the window and looked out. Helena was not in sight, and, with a sigh, the stout lad turned away. A special car had been reserved for the boys from Cresville and vicinity, who were going away in a body, and the lads now filled the coach with gay songs and jests. To most of them it was a holiday, a picnic, but there were some who felt the gravity of the situation, and who felt that doing their duty in the matter of enlisting was not as easy as it seemed. The three motor boys kept together, and soon had stowed away their possessions and made themselves comfortable. “Well, this is the first time we ever left Cresville under such circumstances,” observed Ned, as the train pulled out of the station amid cheers from those left behind, and a stirring air played by the band. “Yes, we’ve gone out on many a trip, but none was just like this,” agreed Jerry. “I wish the professor could be with us, at least part of the way. He’d be interested in this bunch.” “More likely he’d be crawling around on the floor of the car looking for a new kind of fly,” said Bob, with a chuckle. Professor Snodgrass had gone back to Boston after his flying visit to Cresville. But he had promised to go to see them in camp, for it was evident that, on account of the war, he would not be kept very busy at Boxwood Hall. Soon the prospective soldiers in the special car were having the best of times. They had gotten over the first wrench of parting, and were having fun. They sang and joked, and Ned, Bob and Jerry entered into the jollity of the occasion. “Do we go right into camp?” asked one lad from Cresville.
