The house at _Reykjahlið_, is an ancient one built of turf and stone with the usual turf roof, covered with grass in a flourishing condition. In front of the house is the only windmill that I have seen in Iceland. The sails are of galvanized iron and laid on the yards in squares like the glass in a window. The mill is a small affair and is used to grind barley and rye for the use of the family. No grain is raised in the country but it is all imported from Europe and ground as needed. The entrance to the house, like the one described in the chapter on _Hekla_, is through a hallway with an age-trodden floor. The guest room is finished in wood and we found it neat and clean. We are glad to report this state of cleanliness because the English writers tell strange tales about the uncleanliness of this house and its vermin-infested guest room. The people at the farm spoke no English but they waited upon us with the customary Icelandic cordiality and we thoroughly enjoyed the several meals prepared especially for our table. The trout came fresh from the lake and the prime eggs from ducks’ nests on the islands. [Illustration: _A Hot Water Fall at Hveravellir._ _Slútness, Crater Island in the Mývatn. Home of the Golden Eyed Duck._] One day I found a magnificent specimen of an edible mushroom, _Lycoperdon giganteum_, and to the horror of the people on the farm I requested that it be cooked. This specimen was ten inches in diameter, hard, white and in prime condition. It had been long since we had tasted mushrooms and our vegetable diet had been a sparing one since we left the steamer, so I persisted, through Ólafur, that “the Americans really mean that they wish this mushroom cooked and they will eat it.” Our directions were carefully followed and the _Lycoperdon_ came to the table well prepared and in full flavor. What consternation it created in the kitchen we will never know, save that there was much talking there and uproarious laughter in that department during the cooking process. The maiden who brought it to the table came in with a blushing face and ill-concealed laughter at some remarks that followed as she left the kitchen. It certainly was delicious and after we had dipped deeply into the contents of the tureen, Ólafur was persuaded to try it and the farmer standing in the doorway looked aghast when he saw Ólafur eat it. Ólafur pronounced it good and invited the farmer to try it but the latter shook his head in a manner to convince us that he had no idea of being so unwise as to eat such a thing. On the following morning when I called for the remainder, the response was,—“it is all gone.” Whether they threw it away or whether it was eaten after consultation with Ólafur I will never know for a certainty but I believe that it was eaten, also I believe that every sizable _Lycoperdon_ growing on this farm in the future is destined for the stew pan with real cream.
