To remain young is one of the difficulties of being agreeable. Whoever does so is obliged to adopt the Aristotelian maxim of moderation, Placidity of temper is necessary to the clear-pencilled eyebrow and the magnolia complexion. Frowns, weeping, excitement, despair and laughter wrinkle the face. Nature keeps women's forms well rounded to extreme old age, and their faces remain agreeable when they take the trouble to keep them so. The brow, the fair front, need never be furrowed. Of all we meet in the street, very few have tranquil, undistorted faces: the old are screwed out of shape, the young are going to be so. A well-preserved beauty is one who neither puckers her face into wrinkles nor mauls it with her hands: she never buries her knuckles in her cheeks, nor rests cheek on palm or chin on hand, nor folds her fingers around her forehead while reading, nor rubs her "argent-lidded eyes." She veils her face from the wind; she does not work with uncovered neck and arms: therefore they do not become tawny. She avoids immoderate toil, which makes the hair to fall, the features sharp, the skin clammy and yellow. She avoids immoderate laziness, as causing obesity and a greasy complexion or pallor, lassitude and loss of vitality. Such are; the difficulties of being agreeable. M. D. OUR SUB-GARDENER. He who doubts that civilized progress and industry is beneficial to birds, and promotes their comfort and multiplication, never saw the robin and the purple grakle following the plough on a summer's morning. The ploughman is not more punctually afield than his unbidden but welcome feathered attendants. They are ahead of him, perched patiently in the trees that dot fence or hedgerow. They see the team afar off, and as the gate rattles in opening for its admission the glad tidings is sent down the line in whistle or chirrup, the most musical of breakfast-bells. The worm that but for the intrusive ploughshare would blush unseen beneath the soil, and but for the feathered detective on the lookout for him would regain his subterranean retreat, might take a less cheery view of the philosophy of the matter; but he too is, taken collectively, favored by tillage and fattens on high-farming like an English squire. But we are not at present occupied with his feelings. Somebody must suffer in the battledore game of eat and be eaten, and we shall let the chain of continuous destruction rest here with the grub that reaps where he hath not sown. Horse, man and bird are honestly and harmoniously picking up a living at the expense of a fourth party that also thrives in the long run.
