"I think you are about the prettiest, jolliest ever. I wish you would let me go off to Mexico engaged to you. It would make it lots easier to work and I mean to work like a whole regiment and make good. Won't you, Tillie?" "Well, I don't care if I do. You are a fine dancer and I think a heap of you, Bill. I'd rather keep it dark, though, if you don't mind, as it queers a girl's game sometimes if she gets engaged." "Lord, no! I don't mind just so I know it myself," and the happy Bill enfolded his enamorata in his arms, although she carefully admonished him not to crush her new dress. "I never dreamed you were thinking about me seriously," she confessed as she emerged from his embrace. "Honest? Been dotty about you ever since you took me for a jitney driver and tipped me a quarter. Got it yet." "Look how dark it is! I believe we are going to have a storm. What a great black cloud! Let's hurry, as I have no idea of getting my frock wet." Hurry they did and reached the pavilion just as great drops began to fall. Bill was in a state of happy excitement over his engagement, although it was something he must keep to himself. He felt like shouting it on the housetops, but instead he gave one of his great laughs that startled Mrs. Carter so she stopped dancing and hunted up Bobby. "It sounded like bears and lions," she declared, "and I felt uneasy about my baby." She found that youngster fast asleep cuddled up in his father's arms, the father looking very happy and peaceful. Robert Carter felt quite like a little child himself with his great girls taking care of him. CHAPTER VII THE STORM That storm was always known as "The Storm" by everyone who was at the Week-End Camp on that night in August. Greendale had been singularly free from severe storms that season and the Carters had had no difficulty up to that time in keeping dry. They had had rain in plenty but never great downpours and their mountain had escaped the lightning that on several occasions had played havoc not many miles from them. The day had been exceptionally warm but very clear. The full moon had taken the place of the sun when night came on and so brilliant was the glow from that heavenly orb, one could almost fancy heat was reflected as well as light. The great black cloud that came rolling over the mountain was as much an astonishment to the dancers in the pavilion as it was to the moon herself. They refused to recognize the fact that a storm was coming up and the moon also held her own for some time after the downpour was upon them. She kept peeping out through rifts in the clouds and once when the storm was at its fiercest she sailed clear of all clouds for a few moments, and then it was that the rarest of all beauties in Nature was beheld by the damp and huddled-up crowd of week-enders: a lunar rainbow. It stretched across the valley, a perfect arc with the colors as clearly defined as a solar bow but infinitely more delicate than any rainbow ever beheld before.
