In the part pointed to the north is Lewis, along the coast quite frequently cultivated. It has four churches, one castle, seven largish rivers and twelve smaller ones in addition, all according to their size producing salmon: in very many places the sea penetrates the land and spreads into gulfs, all abundantly supplying herring. There is here great production of sheep, which wander freely on moors and in woods. They are each year driven into a narrow place or fold, and the inhabitants shear them in the old manner. A great part of the flat land consists of moors; in them the earth on top is black from the combination over many centuries of moss and rotting trees, to a depth of about a foot. This upper crust is cut into oblong, thin blocks, and dried in the sun. It is then collected to use for fire, and is burned in place of wood. In the following year the bare soil is manured with seaweed and sewn with barley. In this island such a large number of whales is often caught that sometimes (as older men relate) twenty seven, some very large and some smaller, have been offered to the priests as tithes. There is in this island a large cave, in which when the tide recedes water two fathoms deep remains; when it comes in, the depth is more than four. Sitting there on the rocks, a huge crowd of every class, sex and age indiscriminately take a great amount of fish by hook and line.
