Sandie soon found that he could do every portion of the exercises, difficult though they were, except one. That he could not bring out. After finishing all the rest, he pored and posed over this for one long hour. His head felt splitting in twain, strange nervous tremors ran along his limbs, and the cold sweat burst out from every pore.
At last a strange drowsiness stole over him. He put up his feet upon the seat, leaned his head upon his folded hands, and fell fast asleep.
Now, account for it as you may, reader, account for it if you can, I but state a fact when I say that in a dream Sandie got out of his difficulty, and saw the question written plainly out before him.
He was hardly awake when he sprung up and recommenced to write, fast and faster, and presently the thing was done.
“Hurrah!” he shouted, “Eureka!”
He really could not help it.
The Professor looked a little surprised, but smiled.
“I hope you enjoyed your nap,” he said.
“Did I sleep long?” said Sandie.
“Only two hours.”
