The rain-gauge from which the above results have been 
obtained is situated on the easterly slope of the valley of the 
Nayden Brook, which is a tributary to the River Roach. 
This brook takes its rise in the ridge of hills between 
Rochdale and Haslingden, its general direction being from 
north to south. The gauge is about 150 feet above the 
stream and 900 above the level of the sea. 
From the bottom of the valley to the top of the hills, 
eastward and westward, there is a rise of from 500 to 600 
feet in half-a-mile. 
A paper was read by John Graham, Esq., V.P.C.S., 
“ On the Consumption of Coals and rate of Evaporation 
from Engine Boilers.”
