Lycksele Lappmark, 05/06/1732, ¶387:

Nature, which has given man everything in abundance and provided for him so well that he lacks nothing, has even given him bedclothes in this desolate wilderness. ‘Polytrichum prolif., maximum Vaill.’ [moss], “Romsi” in Lappish, grows in wettish and damp woods here.18 They cut all round a piece the size they want their bed to be, cut it free on the underside and pick it up from the ground. It is not especially branchy but the roots are so tangled that it cannot fall to pieces. This moss is soft and does not go lumpy when you lie on it; in fact, it holds its own against the finest bed. The same sort of moss can be used on top as a coverlet. I would be tempted to say that quilts are merely imitations of this if I knew of anyone who had given an earlier description of the moss. I have slept in it and been filled with admiration. It is necessity that has taught the Lapps this. This bed can be squeezed together from the sides and tied into a little bundle slim enough to be held in 2 hands. They take it with them and keep it for the next night when, after being sprinkled with a little water, it regains its former elasticity.
