Everyone slept soundly that night. So soundly, in fact, that the sun was very high when Koku was the first to awaken, His head felt strangely dizzy, and he wondered at a queer smell in the room he had to himself.
"Nobody up yet," he exclaimed in surprise, as he staggered into the main cabin. There, too, was the strange, sweetish, sickly smell. "Mr. Tom, where you be? Time to get up!" the giant called to his master, as he went in, and gently shook the young inventor by the shoulder.
"Eh? What's that? What's the matter?" began Tom, and then he suddenly sat up. "Oh, my head!" he exclaimed, putting his hands to his aching temples.
"And that queer smell!" added Ned, who was also awake now.
"Bless my talcum powder!" cried Mr. Damon. "I have a splitting headache."
"Hum! Chloroform, if I'm any judge!" called Mr. Nestor from his berth.
"Chloroform!" cried Tom, staggering to his feet. "I wonder." He did not finish his sentence, but made his way to the room where his camera was kept. "It's gone!" he cried. "We have been chloroformed in the night, and some one has taken my Wizard Camera."
