inexplicable and interesting to watch him pretty closely.

He saw Mr. Carrington stoop down by the side of the pool, with his hand
against the old alder stem, and peer into the water, but of course he
could not appreciate the surprise and pleasure with which Mr. Carrington

was, a foot long and more, brown and jointed like a scorpion.

Its ugly apparition and the sharp amazing painfulness of its bite were

yelled aloud. Over he toppled, face foremost, splash! into the pool.
