By the middle of August rabbits were uoticeabty less abundant 

 than they had been a month earlier. Then, too, we began to find them 

 dead in the trails, evidently from some disease. It seemed apparent 

 that they were beginning to suffer from the ravages of the epidemic 

 that periodically reduces the northern rabbits, though from all 

 accounts their numbers locally had not yet reached the maximum that 

 was to be expected. This was bvit the second year of increase since 

 the last period of scarcity, we were told.
