"Did you ever hear tell of Graham's Glacier?" he demanded.
"Certainly," I replied, astonished; "it's the southernmost glacier in British America."
"Right," he said. "And did you ever hear tell of the Hudson Mountings, mister?"
"Yes," I replied.
"What's behind 'em?" he snapped out.
"Nobody knows," I answered. "They are considered impassable."
"They ain't, though," he said, doggedly; "I've been behind 'em."
"Really!" I replied, tiring of his yarn.
