For three hundred years potatoes have been a cooking, and yet not one in in a hundred knows how to cook one properly. We never eat a sodden, tasteless tuber without wishing that there was a cooking school in every town. There are some in some towns. One of considerable pretensions exists at Auburndale, Mass. It is in connection with Lasell Seminary. If we had girls to send there we should get ourselves invited to dine. If the potatoes were properly cooked, it would be enough. Any one who knows how to cook a potato properly, has the proper foundation for all the rest.
