Perhaps it is one's involuntary sense of this haunted antiquity that gives its peculiar expressiveness to the solemn, almost religious quiet of barns and stables, the, so to say, prehistoric hush of brooding, sun-steeped rickyards; and gives, too, a homely, sacerdotal look to the implements and vessels of the farm. A churn or a cheese-press gives one the same deep, uncanny thrill of the terrible vista of time as Stonehenge itself; and from such implements, too, there seems to breathe a sigh--a sigh of the long travail and unbearable pathos of the race of men. You will thus see the satisfaction, in moods of such meditation, of carrying in one's knapsack a line from Virgil--"the slow-moving wagons of our Lady of Eleusis"--and I congratulated myself on my forethought in having included in our itinerant library a copy of Mr. Mackail's beautiful translation of "The Georgics." Walt Whitman, talking to one of his friends about his habit of carrying a book with him on his nature rambles, said that nine times out of ten he would never open the book, but that the tenth time he would need it very badly. So I needed "The Georgics" very badly that afternoon, and the hour would have lost much of its perfection had I not been able to take the book from my knapsack, and corroborate my mood, while Colin was sketching an old barn, by reading aloud from its consecrated pages: "_I can repeat to thee many a counsel of them of old, if thou shrink not back nor weary to learn of lowly cares. Above all must the threshing-floor be levelled with the ponderous roller, and wrought by hand and cemented with clinging potter's clay, that it may not gather weeds nor crack in the reign of dust, and be playground withal for manifold destroyers. Often the tiny mouse builds his house and makes his granaries underground, or the eyeless mole scoops his cell; and in chinks is found the toad, and all the swarming vermin that are bred in earth; and the weevil, and the ant that fears a destitute old age, plunder the great pile of spelt_." Perhaps some reader had been disposed hastily to say: "What did you want with hooks out of doors? Was not Nature enough?" No one who loves both books and Nature would ask that question, or need to have explained why a knapsack library is a necessary adjunct of a walking-tour.
