is words were cut short by a very unusual incident.
A thin, high scream came suddenly from above our neat stuccoed hangars at the edge of the white field. I looked up quickly, to catch a glimpse of a bright object hurtling through the air above our heads. The bellowing scream ended abruptly in a thunderous crash. I felt a tremor of the ground underfoot.
"What—" I ejaculated.
"Look!" cried Charlie.
He pointed. I looked over the gleaming metal wing of the Golden Gull, to see a huge cloud of white sand rising like a fountain at the farther side of the level field. Deliberately the column of debris rose, spread, rained down, leaving a gaping crater in the earth.
"Something fell?"
"It sounded like a shell from a big gun, except that it didn't explode. Let's get over and see!"
We ran to where the thing had struck, three hundred yards across the field. We found a great funnel-shaped pit torn in the naked earth. It was a dozen yards across, fifteen feet deep, and surrounded with a powdery ring of white sand and pulverized rock.
"Something like a shell-hole," I observed.
