Down, down , down we climbed. The climb was very hard, but in the afternoon, we were at the bottom. I sat down to rest. I imagined the volcano suddenly erupting, with rocks, ash, and Iava coming out. this is a terrible idea! I thought, but the professor did not seem to fell this way . He was very happy, and he ran here and there, looking at everything. suddenly, he called, axel,come here! and pointed to the wall. on the wall,I could see the word arne.
