All day I have been brushing past waggons heavily loaded with merchandise, each drawn by five and six horses; the whole road in fact appears like the cavalcade of a continued fair.

About nine miles from Bedford I first observed {15} the occurrence of fossil shells, consisting of terebratulites, and amongst them the Anomia trigonalis of Martyn, with some other species. They occur in the sandstone employed for mending the road, with which also alternates much liver-brown argillaceous shale.
