Mary Daniels is a student in England. This year she had a very interested
summer holiday. He travelled with fifteen others people to the Tuwenzori Mountains
in Africa. They went there to help make a road through a forest among two big towns.
“It was very difficult because of there was no water to drink and no shops that we
could buy food,” said Mary. “It was also very cold and wetter in the mountains. It is
one of the wettest place in the world.” Mary stays in the mountains for six weeks. It
was hard work, but she said it was best thing she had ever done. She is hoping to
return next year to do some more work there.
