REPORT AND OBSEEYATIONS ON 



Observations are now being carried on by the Bolton 

 Waterworks Company which will throw much light on this 

 subject ; but they are not yet in a condition to be laid before 

 the public, though it is hoped, at a future time, when the 

 observations are completed, permission may be given to 

 use them. 



The rain at Belmont, in the Bolton Waterworks district, 

 for the last five years, is as follows, — the elevation 850 feet. 



The returns for 1843 and 1844 have been given in former 

 papers, but they are introduced again for the purpose of 

 bringing all together. Here the gauge has been emptied 

 every month, the index rod being allowed to rise during 

 that period, and the returns are therefore liable to the ob- 

 jection before alluded to. The quantities registered may 

 be somewhat too high. 



By the kindness of Mr. John Ecroyd of Rochdale, the 

 following table of rain which has fallen at that place for the 

 last sixteen years is introduced.
