 no two meadows in the neighbourhood of 

 Salisbur}^ which use precisely the same 

 water. I have seen these meadows, and 

 have seen that they use the water in 

 the same way that the meadows on 

 other streams use it. After one mea- 

 dow has used it, it returns into the bed of 

 the stream, and receives additional matter, 

 before it is used again. In a rainy season, 

 there is no one meadow, in that range, 

 which uses all the water ; therefore every 

 meadow has a certain portion of what is 

 called the first water ; and there is then a 

 continual influx of fresh water, and fresh 



matter
