At the conflux of the rivers Louther and Eimont there is a remarkable curiosity, that illustrates the method of the religious solemnities of the old Britons, as much as any I have seen. Upon the edge of the Louther, where the bridge now passes it, is a delicate little plain, of an oblong form, bounded on the other side by a natural declivity: this is used to this day for a country rendezvous, either for sports or military exercises, shooting with bows, &c. On this plain stands the antiquity commonly called King Arthur’s Round Table, and supposed to be used for tilts and tournaments: it is a circle inclosed with a ditch, and that with a _vallum_. At first sight we may see that it was intended for sports, but not on horseback, because much too little: the _vallum_ on the outside lies sloping inward with a very gradual declivity, on purpose for spectators to stand around it; and it would hold at least 10,000 people. The outside of the _vallum_ is pretty steep: it was high originally, as may be seen now in some parts; but it is worn down, as being by the side of the common road; and the inhabitants carry it away to mend the highways withal. There are two entrances into the _area_, north and south, or nearly so: one end is inclosed into a neighbouring pasture: the _area_ had a circle within, somewhat higher in elevation than the other. The outer verge of the _vallum_ is a circle of 300 foot: the composition of it is intirely coggles and gravel, dug out of the ditch. Upon part of the plain are marks of the tents of the Scots army, that accompanied King Charles II. in his way to Worcester: they encamped here for some time, and drew a small line across part of the southern circle: this was done within memory. Just 400 foot from the verge of the south entrance is another circle, 300 foot in diameter, made contrarywise to the former: the _vallum_ is small, and the ditch whence it was taken is outermost. Thus these two circles and the interval make 1000 foot in length; and there is just room enough without them, next the river and next the bank, for a _circus_ or foot-race, according to the old manner of the Grecian, which were always celebrated by the sides of rivers.
