What has done this?
Exercise, actual hard work, digging in the dirt.

We are made of dust, and the closer our companionship with Mother Earth in summer time the longer we shall keep above ground.

Then the freedom from conventional restraints of dress; no necessity for "crimps," no need of foreign hirsute adornment, no dresses with tight arm holes and trailing skirts, no high-heeled slippers with pointed toes, but comfort, clear comfort, indoors and out.
Plenty of rocking chairs, lounges that make one sleepy just to look at them, open fires in every room, and nothing too fine for the sun to glorify; butter, eggs, cream, vegetables, poultry--simply perfect, and the rare, ecstatic privilege of eating onions--onions raw, boiled, baked, and fried at any hour or all hours.

I said comfort; it is luxury! Dr.Holmes says: "I have seen respectability and amiability grouped over the air-tight stove, I have seen virtue and intelligence hovering over the register, but I have never seen true happiness in a family circle where the faces were not illuminated by the blaze of an open fireplace." And nature! I could fill pages with glowing descriptions of Days Outdoors.

In my own homely pasture I have found the dainty wild rose, the little field strawberries so fragrant and spicy, the blue berries high and low, so desirable for "pie-fodder," and daisies and ferns in abundance, and, in an adjoining meadow by the brookside, the cardinal flower and the blue gentian.
