rivers, indeed, are doubly equipped in 

 that respect. Of these the Tay is an

 Loch Lyon to draw upon. If either of 

 these lakes, at the narrow outflow, were 

 fitted with a sluiced dam a few feet high, 

 the river would not need, even in the 

 severest summer drought, to be lower 

 than it used to be at such a time before 

 the drainage system was begun. The

When the notion of storage was first
