Nothing came to disturb them, although at daybreak Mr.Tarbill leaped up in alarm.
"Hark!" he cried.

"Somebody is coming! It must be the cannibals!" "What!" exclaimed Captain Spark, and he jumped up, followed by the others.
Then all listened.

From the interior of the little island came a most unearthly screaming.
"Somebody is being murdered!" gasped Mr.Tarbill, and sank on his knees.

"Oh, oh, why did I leave home!" They listened intently, and then Mr.Carr set up a laugh.
"What is it ?" asked Bob, curiously.
"Parrots, my boy, nothing but parrots." "To be sure--I should have knowed it," came from the captain.
"They allers screech like that in the morning." "Are you sure they are parrots ?" asked the nervous passenger.
"Dead certain," answered Mr.Carr.

"If you don't believe it, just go over to yonder trees and shoo them up into the air." "I--I don't think I care to do that--they might fly at me and peck me." "Well, they are parrots--and they won't hurt you if you leave 'em alone." During the morning the search for a spring of water was resumed.
At last they found several pools, the water coming up in them from underground.
