While London draws its water supply from its 

 immediate neighbourhood, some of our great towns 

 have had to go scores of miles away to get their water. 

 Glasgow has an aqueduct 35 miles long from Loch 

 Katrine from which it can draw from 50,000,000 to 

 100,000,000 gallons daily. The works were begun in

 50,000,000 gallons. 



Another aqueduct of great magnitude was con-
