what happen in chapter 14 and 16?

Chapter 14- The group reaches Stapi, which is absolutely beautiful. The people there were not hospitable, their room was dirty and smelly, and Uncle..... he demanded to leave almost immediately and go on with their journey.

"My uncle soon discovered what sort of a man he had to do with; instead of a good and learned man he found a rude and coarse peasant. He therefore resolved to commence the grand expedition at once, and to leave this inhospitable parsonage. He cared nothing about fatigue, and resolved to spend some days upon the mountain.

Chapter 16- The men had reached Snæfell and proceeded to descend into the crater.
