Leaven in the Schools Set.—Dr. Lewis's g rim application of Grcsham's

law to public schools will be endorsed by many people's experience of seeing the leaven depressed by the dough. But cookery is also an art, and I have no doubt that bread rises by virtue of the cook as well as of the leaven. It may be that the public-school cook, even if he had the skill, did not much desire to see the bread rise, eo irmnitior quia toleraverat. But although one half of my educational experience justifies Dr. Lewis, the other half assures me that it is possible for people who have the art of doing it to bring the general run of children to admire and emulate superior abilities in the arts, in literature and in learning.—Yours, &c., Michael Hall, Kidbrooke Park, Forest Row.
