Saturday, 29th May 1847. 
Party assembled at North British Railway Station at 7.15 a.m. 
The morning was very wet, and rain was falling copiously 
without much prospect of clearing. The number who met was 
about 12. They resolved to put off the trip till 11.30 in the fore- 
noon. By that time the weather was more promising, and a 
party of 16 started by the train for Drem, thence they walked to 
Dirleton, visited the castle and grounds, Archerfield, Gullan, 
Luffness, Aberlady, and returned by train which passed Long- 
niddry about 7 p.m.
