Jimbo shuddered as he heard her.
"When can we try?" he asked anxiously.
"Very soon now. The muscles must harden first, and that takes a little time. You must practise flapping your wings until you can do it easily four hundred times a minute. When you can do that it will be time for the first start. You must keep your head steady and not get giddy; the novelty of the motion—the ground rushing up into your face and the whistling of the wind—are apt to confuse at first, but it soon passes, and you must have confidence. I can only help you up to a certain point; the rest depends on you."
"And the first jump?"
"You'll have to make that by yourself," she said; "but you'll do it all right. You're very light, and won't go too near the ground. You see, we're like bats, and cannot rise from the earth. We can only fly by dropping from a height, and that's what makes the first plunge rather trying. But you won't fall," she added, "and remember, I shall always be within reach."
"You're awfully kind to me," said Jimbo, feeling his little soul more than ever invaded by the force of her unselfish care. "I promise you I'll do my best." He climbed on to her knee and stared into her anxious face.
"Then you are beginning to love me a little, aren't you?" she asked softly, putting her arms round him.
"Yes," he said decidedly. "I love you very much already."
Four hundred times a minute sounded a very great deal of wing-flapping; but Jimbo practised eagerly, and though at first he could only manage about twice a second, or one hundred and twenty times a minute, he found this increased very soon to a great deal more, and before long he was able to do the full four hundred, though only for a few minutes at a time.
He stuck to it pluckily, getting stronger every day. The governess encouraged him as much as possible, but there was very little room for her while he was at work, and he found the best way to practise was at night when she was out of the way. She told him that a large bird moved its wings about four times a second, two up-strokes and two down-strokes; but a small bird like a partridge moved its wings so rapidly it was impossible for the eye to distinguish or count the strokes. A middle course of four hundred suited his own case best, and he bent all his energies to acquire it.
