Abstract
On March 9th, 1892, I had the honour of reading a short paper before the Society on the sections seen along the course of this new railway, dwelling chiefly on the cutting north of Hornchurch, in which a considerable mass of Boulder Clay had appeared, having a maximum thickness of 15 feet, and a horizontal extension of about 300 yards. The Boulder Clay lay in a slight hollow on the surface of the London Clay, and was covered by gravel belonging to the highest terrace of the Thames Valley system in the district, the surface of which varies from 90 to 120 feet above Ordnance datum. At that time, and during many months afterwards, but little work was done in the cuttings nearer Romford than that just mentioned. The cutting at Butts Green and the more northerly excavation between Great Gardens and the junction with the Great Eastern Main Line at Romford remained in an almost stationary state. During the period between the spring of 1892 and that of 1893 I visited these cuttings many times, though without detecting anything but London Clay and gravel: more London Clay being visible at Butts Green than nearer Romford. However, last year the Romford cutting was considerably widened and deepened, and afforded sections of much greater interest than I had anticipated.
