OBSERVATIONS ON THE FALL OF RAIN. 185 
which there lies tolerably level bedded. The

deposition or precipitation of rain, as the clouds, 
after dragging over the first high ground, will 
rest awhile in the first trough, formed by the 
Belmont valley, before they are carried over 
the second summit to the Turton and Entwistle 
valley. 
The general results, however, may be expected 
to be pretty much the same, and it will therefore

connect the different kinds of information which 
the two valleys now furnish. 
We find that in an average year, the water 
collected and discharged from the Turton and 
Entwistle reservoir, is equal to nearly forty

and during last year, which was very little more
