"I'll make a try for it anyway." But Jack, being more simply dressed, was as good as his word, and plunged into the creek first. Harry was scarcely half a minute behind. The boys swam, dived, and frolicked as boys of their age will, and were loath to come out at the last. After their experience of mud and heat the bath seemed to them delicious.

"I haven't enjoyed myself so much since I came to Australia," said Harry with a deep sigh of satisfaction. "I wish I could have a bath every evening."

"So do I," said Jack; "I mean to have another to-morrow morning."

They slept soundly all night, but early in the morning, as consciousness returned, Harry was startled by the sound of hearty laughter. He looked at Jack and Obed in amazement, but both were fast asleep. Indeed, the sound seemed to come from above. He looked up into the tree beneath which they had encamped, but could see no person concealed among the branches. He did, however, notice a peculiar looking bird, and it dawned upon him that the laughter proceeded from it. He remembered now to have heard of the bird peculiar to Australia, popularly known as "the laughing jackass." This was the first chance he had had of hearing it, and he woke up Obed and Jack to hear it also.

"That beats all I ever heard," said Mr. Stackpole. "I wish he'd tell us what's the joke, and we'll laugh too."

This was not the only sound they heard. A flock of white cockatoos were roosting on the tree, and favored the party with their dissonant cries. They are described as having "most sharp and rasping voices."

"If that's singing," said Obed. "I shan't be afraid to try it myself."

"Don't you sing, Mr. Stackpole?" asked Jack, smiling.

"I thought I could once, when I was in my teens. I attended a singing school, and went in the attic one Sunday mornin' to practise. Soon my father was at the foot of the stairs, and asked me what I meant by sawin' boards up in the attic Sunday mornin'."

Of course the boys laughed, but in spite of Obed's disclaimer thought they would prefer listening to him to the cockatoos.
