Excursions. 
The following excursions have taken place during the past 
year :— 
1st. April 8th, 1899.—To Merstham, to visit the new railway 
cutting. Of this meeting Mr. Robarts sends the following 
notes :— 
‘¢ An excursion to Merstham took place on April 8th, when a 
party of thirteen met under the guidance of the President. The 
unfavourable meteorological conditions—the day being sleety 
with strong cold wind—no doubt prevented members from 
coming in greater numbers. 
‘The new London, Brighton, and South Coast cutting south 
of the Merstham tunnel was first visited. The entrance to the 
cutting was found to be in the gault, which dipped to the north, 
and consisted of dark sandy clay, with few fossils except forami- 
nifera. The higher beds were of lighter colour, and merged in- 
sensibly into Upper Greensand, in which no great way up a 
considerable bed of fossils was found by Dr. Parsons. This was 
the more notable, as at an excursion of the Geologists’ Associa- 
tion the year before no fossils were seen. Higher up in the 
series firestone was noted, but the dark greensand at the top of 
the formation was not visible. Traversing the cutting, one or 
two faults were noticed, one particularly with a downthrow of 
about 4 ft.; still more northerly the gault was squeezed up 
nearly to the surface almost vertically for a few feet. 
‘The party then went to an old firestone mine east of the 
northern part of the cutting, which was found to be abandoned, 
though it was being worked the year before. 
‘«« An advance was then made to the chalk-pit, which showed 
the junction of the Middle and Lower Chalk, the massive beds 
and the jointing of the former being in strong contrast to the 
thinner bedding and curved marly fracture of the latter. The 
junction was marked by a narrow yellowish band, which was 
probably the Belemnite Marl. 
‘After inspecting the outside of Merstham Church most of 
the party took tea at the ‘ Feathers.’”’ 
Qnd. April 15th.—To Walton-on-the-Hill, in conjunction with 
the Geologists’ Association, under the guidance of the President. 
The following Report, prepared by Mr. W. P. D. Stebbing, one 
of the leaders of the excursion, is taken from the Report of the 
Geologists’ Association :— 
«‘The members reached Kingswood at 2.2 p.m., and walked 
to the cutting on the western side of the tunnel under Walton 
Heath, in progress for the Chipstead Valley line. At its south-
