THE MOUNT DESERT REGION 315 



Tabanus Linnaeus. Horse Flies 



Around the edges of marshes and ponds is the place for 

 these, but I have found the best hunting on paths and wood 

 roads where they hover on warm mornings. The males are 

 more difficult to find and should be tried for by sweeping the 

 edges of brooks and ponds about dawn.
