Still, grain was not the main element of their diet; they lived chiefly on milk and flesh. In the huts have been found broad vessels that were covered with round discs of slate, and it is probable that these were receptacles for milk or butter, but the milk would mainly be contained in wooden or leathern vessels. Elsewhere their spindle-whorls have been found in fair abundance; not so on Dartmoor--as yet only two have been recovered. This shows that little spinning was done, and no weights such as are used by weavers have been found. The early occupants were in the main clothed in skins. Their huts were circular, of stone, with very frequently a shelter wall, opposed to the prevailing south-west wind, screening the door, which opened invariably to the south or south-west. The whole was roofed over by poles planted on the walls, brought together in the middle, and thatched over with rushes or heather. The walls were rarely above four feet six inches high. They are lined within with large stones, set up on end, their smooth surfaces inwards, and the stone walls were backed up with turf without, making of the huts green mounds. This gave occasion to the fairy legends of the Celts, who represented the earlier population as living in mounds, which the Irish called _sidi_, and the people occupying them the Tuatha da Danann. As already said, this same name meets us in Damnonii, the oldest appellation for the people of Devon. They were a sociable people, clustering together for mutual protection in _pounds_. These pounds are large circular inclosures, the walls probably only about four feet high, but above this was a breastwork of turf or palisading. Outside the pound were huts, perhaps of guards keeping watch. Many of the huts have paddocks connected with them, as though these latter had been kail gardens, but some of these paddocks are large enough to have been tilled for corn. Their plough, if they used one, was no more than a crooked beam, drawn by oxen. It is possible that the numerous sharp flakes of flint that are found were employed fastened into a sort of harrow, as teeth. Their cooking was done either in pots sunk in the soil, or in holes lined with stones. Rounded pebbles, water-worn, were amassed, and baked hot in the fire, then rolled to the "cooking-hole," in which was the meat, and layers of hot stones and meat alternated, till the hollow receptacle was full, and the whole was then covered with sods till the flesh was cooked. The following account of the manner in which the Fiana, the Irish militia, did their cooking in pre-Christian times will illustrate this custom:--
