Some remarks on vegetable instinct, and an eloquent trib- 

 ute to the utility and happy character of the Field Meetings, 

 closed this address, which met throughout the hearty appro- 

 bation of all. 



Dr. George Osgood of Danvers said that he had been both 

 pupil and friend of Dr. Cutler, whose name is so dear to the 

 people of Hamilton. He had rambled in these woods with 

 him fifty-five years ago, when he stood as one of the pioneers 

 of American Botany. From him he had his first lessons in 

 that study of nature, which during a long life, have given

S. P. Fowler of Danvers read the following essay on the 

 Cha7iges produced by civilization hi the habits of our common^ 

 birds. 



Civilization has produced no greater changes in our coun- 

 try, than it has in the habits of our common birds. Our oc- 

 cupations, architecture, mode of cultivating the soil, habits, 

 opinions, and even our legislation, serve to produce this 

 change. The establishment of a fort, or fur post in the Indi- 

 an country, or the opening of the forest for a clearing, by th6 

 squatter, effectually and at once changes the mode of life of 

 many of our birds. Thus we see the near relation they sustain 

 to us. But I wish more particularly to notice at this time the 

 changes that have taken place in the habits of our birds in 

 Essex County, during a period of fifty years. None have 

 been noticed, I think, in our rapacious birds. They have 

 become less numerous than formerly, although they con- 

 tinue to breed among us. The Baltimore Oriole still con-
