Jokkmokk [2], 27/07/1732, ¶885:

27th. I noticed that reindeer like eating water horse-tail (“Åsche” in Lappish), Equisetum. They do not like eating it once it is dry and I was amazed, therefore, at the negligence of the Lapps in not harvesting horse-tail and reindeer moss in the summer, as farmers do, in order to have something to fall back on when the snow-crust freezes hard and they risk losing everything they possess.
