the other side the river: there are likewise the footsteps of the fortifications round the town, thrown up with bastions in the time of the civil wars. Under those on the south side, descending into a stone quarry which has abundance of intricate turnings, I saw a piece of oak wood, as big as both one’s hands, lie between the _strata_ of solid stone: though petrified, the ligneous fibres when split would burn in a candle. I suppose it to have been lodged there in the deluge. A little way from the town, about Sprotton, are the pits where they dig up tobacco-pipe clay. Near Billing, about three miles from Northampton, not far from the earl of Twomond’s seat, was lately found a mine of copper, and coal, and marble, as they told me. [Sidenote: TAB. XII.] [Sidenote: +Guildsborough.+ Roman _Camp_.] From Northampton, over the river, by a large stone bridge where is an old religious house, half a mile off in the London road, is another of queen Eleanor’s stone crosses, called Queen’s cross, with her images and arms. It stands on a hill in the open country upon eight steps, in form much like that of Waltham, of which I have given a print. On the other side of the town, about three miles distance, is Holdenby house, which lies in noble ruins: here king Charles I. was kept prisoner. A little way off is Naseby,[33] where the bloody and fatal battle happened between his forces and those of the parliament, upon a fine plain where at present stands a windmill: the marks of several great holes appear, where the slain were buried. This town, as near as may be, is the navel of England. Near is Guildsborough, so named from a Roman camp of a square form, and deep ditch, called the Burrows. I was told of several more thereabouts, which I suppose those made in the time of Ostorius about the heads of the rivers here; which all together made a sort of fortification between the north and south parts of the kingdom, especially between the Avon and Severn. A long barrow at Pesford, called Longman’s hill. We saw Althorp, a curious seat of the earl of Sunderland’s, elegantly furnished: there is a fine gallery adorned with good pictures, and a noble library. [Sidenote: +Eston.+]
