The tendinous part of the mind, so to speak, is more developed in winter; the fleshy, in summer. I should say winter had given the bone and sinew to Literature, summer the tissues and blood. – John Burroughs, “The Snow-Walkers,” 1866

Nature looks dead in winter because her life is gathered into her heart. She withers the plant down to the root that she may grow it up again fairer and stronger. She calls her family together within her inmost home to prepare them for being scattered abroad upon the face of the earth. – Hugh Macmillan, “Rejuvenescence,” The Ministry of Nature, 1871
