"Run and call Mr. Dale. He knows something about these cases. He once told me he had a brother who walked in his sleep and did all sorts of strange things."
"All right, I'll call him," answered the shipowner's son, and disappeared down the scuttle ladder.
Going back to the chimney, Dave now saw that Shadow had reached the end of the ridgepole and was kneeling down upon it. Holding out the tape measure he proceeded to make several imaginary measurements, all the while muttering to himself. The sight almost caused Dave's heart to stop beating, for the slightest miscalculation on the sleep-walker's part would have caused a serious if not fatal accident.
After what seemed a long time Dave heard Phil coming back. He was accompanied by Andrew Dale, the head teacher, who had stopped just long enough to get on some of his clothing.
"Where is he?" whispered Mr. Dale, as he came out in the wind and rain.
"There," answered Dave, and pointed out the form of the sleep-walker.
"Have you tried to speak to him?"
"No, I was afraid."
"Then, don't say a word till he comes down to a safer place."
After that the three watched Shadow Hamilton for several minutes while he continued his calculation and used the tape measure. Then they saw the sleep-walker wind up the measure.
