It will therefore be a matter of surprise to many readers to learn that the highest and byfar the most formidable of them is not located in Iceland, nor in the Yellowstone National Park, nor inNew Zealand, but in the little Republic of Costa Rica, on the northern boundary of Panama. The columnof steam and water, shown in this picture, is 1,00o feet high.
