time in Great Britain are six-inch cubes, or still smaller, with a surface four inches square and a depth of seven inches.
But stone pavement when most carefully laid and maintained is noisy and unpleasant to ride over, and in these days we can never reconcile such a pavement with a handsome residence street. The writer experienced a distinct shock when on riding over Euclid Avenue, in Cleveland, last year, he found it still paved with Medina sandstone blocks, and it seemed that this famous street was still living on the reputation which Bayard Taylor gave it years ago as the handsomest street in the world.
