Your paper is so very interesting that the teacher reads to us some of the stories, one of which I liked very much. It was about the forest fires, and we were very anxious to have the next paper come. Some of the other scholars of my school are going to write and tell you what they think is the best story. Good-by, Your friend, EDNA R.C. WESTPORT, CONN., November 12th, 1897. DEAR EDITOR: My teacher has been reading some very interesting articles from your paper, THE GREAT ROUND WORLD. I think the most interesting articles were about the forest fires, the Klondike regions, and about the large and useful bicycles, and about the great wars that are going on now. I think you are very kind in sending your paper to the people. Your friend, IDA B.K. WESTPORT, CONN., November 12th, 1897. DEAR EDITOR: I am very much interested about Cuba and all the wars that are going on, also about Klondike. I wish you would write something about the mines in Mexico, because my father has gone down there to some mines. Yours truly, W.E.W. OGDENSBURG, November 14th, 1897. DEAR YOUNG FRIEND: Many thanks for your kind letter. We will be glad to chat with you about the mines in Mexico as soon as we can find space. THE GREAT ROUND WORLD is a _news_paper. We try to tell you week by week of the important events that have been happening in the world. We have therefore but little room in our pages for any stories that are not closely connected with some recent event. To give you pleasure we will endeavor to make room in the earliest number possible. In the mean while, will you not send us an account of the mine to which your father has gone? He has probably written home to you and told you some interesting things which we should all like to know. Won't you write us another letter, giving us your father's account of the mine he has gone to? EDITOR. INVENTION AND DISCOVERY. POCKET-KNIFE.--Here is an excellent thing in pocket-knives. Attached to the handle is a revolving plate which, when the knife is opened, turns round and catches the blade firmly, making it impossible for it to close and holding it absolutely rigid. So many accidents have occurred through the slipping of the pocket-knife that it seems strange such a simple device as this should not have been thought of before. [Illustration: Pocket-knife] We are aware that there have been several knives made with springs to hold the blade firmly when open, but these have all been large and clumsy knives, whereas the one illustrated is really what it pretends to be--a pocket-knife.
