Students who get tired of looking at the four walls of a classroom might like to take the nature course being offered by Carvel College again this summer．Groups of about a dozen students each，led by an experienced guide，will go on ten﹣day camping trips to the mountains to study the plants and animals that grow and live there．

Students carry their own things，which includes sleeping bags，warm clothing，food and water，and other useful tools．And what do the students do all day？Well，as soon as the sun comes up，they eat breakfast and start climbing up the mountain trail to the next campground，which is five to ten miles away．As the students take notes，the guide points out different plants and animals alongside the trail．The climb is usually over by early afternoon，so the group spends the rest of the day resting or swimming in a mountain lake．Before dinner each night，they all come together and discuss the day's activities．

At the end of the course，the students write reports using the information they have collected．But they don't mind at all．What they do mind is leaving the beauty of the wilderness and the good friends they've made to return to their normal lives in the city．
