Mr. Homer Potter handed us a sample of fuel, such as is used on the prairies, in Dakota. It is made of wild grass, firmly rolled into a cylinder, about fourteen inches long and two and a half inches in diameter. It was brought home by his son, Nata, who, with an elder brother have been homesteading it there this summer. This kind of native ruel, is said, answers a good purpose, and two tons of it will do a family for a year. It is a novelty in a tember growing country, and we shall keep it in our office for that purpose.
