Once upon a time there was a camel that ate milkweed and hay. Along came horse and horse asked camel if he wanted to saddle but camel just said humph! Then dog came along and asked camel if he wanted to fetch but camel said humph again! Then ox came along and asked camel if he wanted to plow but camel said humph again! Ox,dog,and horse were all mad now! So the man said that ox,dog,and horse all had to work harder because of camel. The next day a genie came to ox,dog,and horse.Then they said to genie"we asked this camel if he wanted to work but he just said humph! Then the genie said'' that's my camel! Then genie found camel by the pond. Genie said to camel what is all this rudeness I her about you genie asked camel but camel said humph to genie! Camel said humph one to many times so genie gave camel a hump! p.s.earlyer in the story camel didn't have a hump!
