"If all boys were as nice as David the world would be a better place!" exclaimed Grace. "I suppose you can guess what the object of this party is."

"Never mind, don't mention it," said Jessica in a low tone. "Here come some other girls, and if they knew what we know, there would be a multitude instead of a select, private party at the Omnibus House to-morrow."


[CHAPTER IV]

AN UNFORTUNATE AVIATOR

It was an unusual entertainment that David had provided for his little circle of intimate friends in the old orchard surrounding the Omnibus House. There was a look of intense excitement in his eyes, as he stood awaiting his guests, the following afternoon. Mrs. Gray had already arrived, and, leaving her carriage to wait for her near the entrance, now stood by David and helped him receive.

"It's good to see all my children together again," she exclaimed, giving Anne a gentle hug; for ever since her Christmas house party she had acquired a sort of proprietary feeling toward these young people. "I only wish Tom Gray were to be with us to-day. I should like him to have a share in the surprise; for you may be sure there is to be a surprise. David would never have asked us to this lonely place for nothing."

"David is a good old reliable, Mrs. Gray," cried Hippy. "Certainly if I had imagined for a moment that he would disappoint us, I never should have dragged my slight frame all this distance."

"Good, loyal old Hippy," replied David. "The surprise is ready, but even if it had not been, there is no exercise so beneficial to stout people as walking."

"Well, bring it on, bring it on," exclaimed Reddy. "We are waiting patiently."
