In December 1880 the following note of the southern end of the cutting on the Main Line just north of Guildford station was taken, the eastern side having been recut to widen the line:— This section, though not so clear as it was when fresh cut, is still well displayed, and the shell-bed is very distinctly seen. This cutting was described long ago by Prof. Prestwich; but the details of the Woolwich and Reading beds may be useful for comparison with the section on the other side of the valley. The new cutting north-east of Guildford, on the Guildford and Surbiton direct Line, now in process of formation, is of great interest, not only as showing a thick mass of drift, resting very irregularly on the Chalk, but also as again opening up the Reading beds, which are so rarely seen in this neighbourhood. It begins near the eastern end of King’s Road (Stoke road), and in a sharply curving course cuts the London road just north of Alderney Place, and then runs roughly parallel with that road to the south of Oak Lodge; so that it is about a mile long. Owing to the northerly dip the Eocene beds occur only at either end, the central and deeper part of the cutting being more to the south, and showing only chalk beneath the drift, the thickness of which latter, moreover, may have some effect in carrying the boundary-line of the Eocene beds to the north. At the western end
