There are many bogs or mosses of greater or less extent, where the soil cannot be supposed to want depth, though it is too wet for the plough. But we did not observe in these any aquatick plants. The valleys and the mountains are alike darkened with heath. Some grass, however, grows here and there, and some happier spots of earth are capable of tillage.
Their agriculture is laborious, and, perhaps, rather feeble than unskilful. Their chief manure is sea-weed, which, when they lay it to rot upon the field, gives them a better crop than those of the Highlands. They heap sea shells upon the dunghill, which in time moulder into a fertilizing substance. When they find a vein of earth where they cannot use it, they dig it up, and add it to the mould of a more commodious place.
Their corn grounds often lie in such intricacies among the crags, that there is no room for the action of a team and plough. The soil is then turned up by manual labour, with an instrument called a crooked spade, of a form and weight which, to me, appeared very incommodious, and would, perhaps, be soon improved in a country where workmen could be easily found, and easily paid. It has a narrow blade of iron fixed to a long and heavy piece of wood, which must have, about a foot and a half above the iron, a knee or flexure with the angle downwards. When the farmer encounters a stone, which is the great impediment of his operations, he drives the blade under it, and bringing the knee or angle to the ground, has in the long handle a very forcible lever. According to the different mode of tillage, farms are distinguished into long land and short land. Long land is that which affords room for a plough, and short land is turned up by the spade.
The grain which they commit to the furrows thus tediously formed, is either oats or barley. They do not sow barley without very copious manure, and then they expect from it ten for one, an increase equal to that of better countries; but the culture is so operose, that they con-
