of a natural formation, supplied with water by the streams 

 rising in Carter Fell and the adjoining hills. For the retention 

 of the water it has been necessary to build a high dam which 

 crosses the Reed. Difficulties have been experienced in 

 securing a reliable foundation, and in consequence of this 

 it has been necessary to go to a very great depth to obtain a 

 firm support. In the centre of the broad dam crossing a 

 valley there are two strong walls of concrete, and the space 

 between these is being filled up to a great depth with puddled 

 clay. There had been some misunderstanding as to the time 

 of our visit, and we had not the benefit of the explanation we 

 expected from the engineer in charge of the works. The 

 reservoir is in an early stage, but from an inspection of the 

 district it appeared to us that though very great depth will not 

 be obtained, yet an enormous body of water must be retained 

 by the dam. After the inspection of the reservoir, attention 

 was given by those interested to the botany of the district, 

 and the following is a list of the principal plants noticed by 

 them : —
