Dargle & Scalp

13.7.1800 dine at la. Mountcashel's with C(urran) (Dargle & Scalp) / 14.7.1800 Dargle & Water-fall
Dargle is the river that flows to the sea at Bray south of Dublin, and Scalp the name of a hill near that river and the village of Enniskerry, or that is as much sense as I could get out of Google maps
