Fire Island  (English, Paperback, Fenn George Manville)

The words galvanised Smith into action. He had seized and dragged Panton away in time, but as he saw his companion sinking into the crack which grew slowly longer and wider, he stood with his eyes staring and jaw dropped till the words "baccy-box" reached his ears. Then he made a rush to where Wriggs' head and shoulders only remained above ground, stooped quickly, and seized him by his thin garment, and held on, checking further descent and gazing wildly at his messmate, whose rugged features upturned to the red glow of light appeared to be singularly calm and placid.
