HOW WE WERE LIGHTED ON OUR WAY DOWN THE DARK AND SILENT

RIVER.—SUDDEN AND FIERCE ONSLAUGHT UPON OUR BEAUTIFUL BOAT OF

SHELL.—A FIGHT FOR LIFE AGAINST TERRIBLE ODDS, AND HOW BULGER

STOOD BY ME THROUGH IT ALL.—COLD AIR AND LUMPS OF ICE.—OUR ENTRY

INTO THE CAVERN WHENCE THEY CAME.—THE BOAT OF SHELL COMES TO THE

END OF ITS VOYAGE.—SUNLIGHT IN THE WORLD WITHIN A WORLD, AND ALL

ABOUT THE WONDERFUL WINDOW THROUGH WHICH IT POURED, AND THE

MYSTERIOUS LAND IT LIGHTED. 140
