The ignorance of some of the business men of the present day is largely to be attributed to the fact that the instructors of the youth in the olden time never taught them how to carve a dog. How many times have we been in positions since arriving at man's estate, when poring over some great problem of science, where we would have given ten years of the front end of our life if we knew how to make both ends meat, even if it was dog meat? The knowledge that the students of the present day obtain in their study of the dog will be valuable to them if ever they are caught in a melon patch, and a dog fastens his teeth into their garments. They will know how to go to work scientifically to unhinge the jaws of a dog, instead of pulling one way, while the dog pulls the other, until the cloth or the skin tears out. It will be a great thing to know all about how a dog is put together. And if these students are taught how to kill cats they will more than get their money back when they grow up. Ignorant people who have never had the advantages of studying the cat when it is dead, attempt to kill them with boot-jacks and empty ale bottles and tomato cans, but the next generation will know how to do it scientifically, and not hurt the cat. This is certainly an age of improvement, and the _Sun_ desires that school children shall know all about the anatomy of the festive dog and the nocturnal cat, if they don't even know how to spell their own names. BRAVERY OF MRS. GARFIELD The newspaper correspondents about the White House, echoing the remarks made by the doctors, are continually talking of Mrs. Garfield's bravery, and we frequently see the statement made that she is “the bravest woman in the world,” and all that. While expressing great admiration for the gifted lady, in the trying ordeal through which she has passed, and admitting that she is brave as an American woman ought to be, and that by her conduct she greatly braced up her beloved husband when his liver was knocked around into the small of his back by the assassin's bullet, and he didn't know whether he was going to live till morning, we must say that Mrs. Garfield is no braver than thousands of other good women. She simply took the chances on his dying, as thousands of other wives do every day, and for his good she put on the best face possible, and kept her tears back. But how many obscure women have done the same thing, as they sat by the side of their dying husbands, and made the patient believe that he was getting better, and smiled while their hearts were breaking? Was Mrs. Garfield braver than the sister of charity, God bless her, who goes from the North to nurse total strangers in a stricken southern city, when she knows that within a week the deadly fever will kill her?
