 to answer. 



A single glance at the falls tells you in- 

 stantly that they are too high for any salmon 

 to leap. Other rivers with a fall no higher 

 than this one are barred to the salmon, 

 which run up only as far as the falls and 

 then turn back to the sea, or else spawn 

 at the mouths of shallow brooks along the

As you watch, a big salmon flashes up in
