believe this will solve the worst of our difficulties."

I bent over the map.

"You see this volcanic island," said the Professor; "observe that all
the volcanoes are called jokuls, a word which means glacier in
Icelandic, and under the high latitude of Iceland nearly all the
active volcanoes discharge through beds of ice. Hence this term of
jokul is applied to all the eruptive mountains in Iceland."

"Very good," said I; "but what of Sneffels?"

I was hoping that this question would be unanswerable; but I was
mistaken. My uncle replied:

"Follow my finger along the west coast of Iceland. Do you see
Rejkiavik, the capital? You do. Well; ascend the innumerable fiords
that indent those sea-beaten shores, and stop at the sixty-fifth
degree of latitude. What do you see there?"

"I see a peninsula looking like a thigh bone with the knee bone at
the end of it."

"A very fair comparison, my lad. Now do you see anything upon that
knee bone?"

"Yes; a mountain rising out of the sea."

"Right. That is Snaefell."
