EEPOBT AND OBSERVATIONS ON 

 SWINESHAW BROOK.— 1846. 



In this year the index rod of the rain gauge was tied 

 down. The measurement of the stream was suspended 

 during July, August, and September; but it is probable that 

 the 7 inches supposed to have flowed off the ground during 

 this period is not far from the truth. This year was con- 

 siderably below the average fall of rain : nearly one of the 

 driest on record ; and the above results may be taken as the 

 fall and produce in such an extreme period.
