THE MOUNT DESERT REGION 



21 



These range from the cedar swamps where the principal 

 tree is arbor vitae to the ones locally called 'sunken heath,' 

 'bottomless heath,' etc., which are spring fed, and larch, 

 spruce and the like dominate, with some maples. Brush such 

 as Myrica gale and rank grasses begin in these. 



Approaching sea level; swamps and 'heaths' are formed 

 where the water is fresh from the land drainage above or salt 

 from the sea's penetration. Such a place is the bog back of Sea 

 Wall and Great Heath in the northwestern part of the island, 

 which is over 2 miles long and is a mile wide in one place. In 



Swamp l)ack of Schooner Head 



these the vegetation is brush such as Myrica gale, Kalmia, 

 and the like, while the floor of all of them is Spagnum. These 

 places yield insects and at the same time, test one 's endurance. 

 Although the Island had attracted the attention of botanists 

 for years, and they had published the results, no one did so 

 in the case of insects before the Survey, with the exception of 

 an interesting page and a half on the tiger beetles.*^ A number 

 of butterflies obtained by various collectors visiting Mount 

 Desert are mentioned in Scuclder's great work.'^
