THE MEASUKEMENT OF KAIN. 3 



' On the Peak Forest and Ashton Canals, there are only 

 two places where gauges remain on the tops of houses. 

 These are at Marple and at Comb's Reservoir, both on the 

 Peak Forest Canal. 



The comparative results between the old gauges placed 

 on the tops of the houses, and the Society's gauges placed 

 on the ground, are as follow : —

Mr. Wood, the Canal Company's engineer, in whose 

 charge the gauges are placed, is of opinion that the Society's 

 gauge at Combo's Reservoir for this year (1845) indicates 

 a greater quantity of rain than was received by the gauge, 

 as he found it to be leaky on removing it to a more conve- 

 nient position. The returns do not show, apparently, any 

 greater discrepancy than is to be observed at other places 

 where no leakage occurred.
