"It's too bad when we are all just beginning to be friends that we must part so soon. Why can't you turn old Dobbin right about face and come back and see us at Camp Sunrise?" "Why not, indeed?" answered Richard. "Do come," urged Billie, never dreaming that in giving this invitation she had been moved by something stronger than her own friendly wish to know more of these nice people, and that destiny itself had a hand in the business. Richard Hook took a little calendar from his pocket and contemplated it gravely. "Another month has perished with her moon," he remarked. "We're in August, little sister. Did you realize that? I see no reason why we shouldn't travel toward Sunrise Camp before----" "Before----" repeated Maggie, and the brother and sister exchanged a swift glance. "Then you do accept," exclaimed Billie joyfully. "With the greatest pleasure," answered Richard, "if you think old Dobbin can climb the hill." "Of course he can," replied Billie. "But, Richard, do you think we dare?" asked Maggie in a low voice. Richard's mouth turned up at the corners and his eyes gave a humorous blink. "We dare anything," he said. "Pray excuse this little aside, Miss Billie. It's only that we are obliged to consider certain complications that arise to vex us at times. I think we can easily arrange to go to Camp Sunrise." Billie was more certain than ever that money was the complication. But surely that was an inexpensive way of spending one's vacation, provided one owned the van and the horse. "How much longer does your vacation last, Mr. Hook?" she asked. "It depends. My boss is a very notionate old party. He might let me go wandering on like this for several weeks longer or he might suddenly decide to send for me, and I should have to go hiking back in the midst of my holiday." Maggie laughed, and Billie wondered what kind of work this unusual young man did that sent out sudden calls in the very middle of hard-earned vacations. However, it was arranged that the caravanners should meander back toward Sunrise Camp and in the course of time stop there for a visit. "They are delightful young people," Miss Campbell said. "I don't know who they are, I'm sure, nor what the young man does, but I find them quite the most charming young people with the exception of my own that I ever met." "It's rather strange about his work," remarked Dr. Hume. "I don't know what he does now, but he wishes above all things to be a farmer, he informed me. He's always looking for farms as he journeys along the road. That's one of the reasons why he got the van, in order to see the country and decide where he'd like best to locate."
