thus offered for either bird or man to leave the more north- 

 ern and cooler place of abode for one so torrid. During 

 migration, this species is not uncommon in company 

 with different other warblers which frequent high woods. 

 In such places, I have usually found them during the first 

 two or three weeks in May, and again in the fall. 



The stomach of this bird was completely filled with in- 

 sects, as far as it was possible to determine, and which 

 were coleoptera, apparently Tenebrionidm, besides the 

 large larva of another kind of b-eetle. 



A STUDY OF GAT HEAD, MARTHA'S YOEYARD. 



By p. R. UHLER. 



ISText the south-western extremitv of Martha's Yine- 

 yard rises a high pile of clays, sands and rocky materials, 

 forming the once detached end of a prominent ridge 

 which bounds the western side of the island. The north- 

 western extension of this prominence is called Gay 

 Head, from the conspicuous colors of numerous radiating 

 beds of yellow, red, white, black and green which cross 

 the face of the bluff. This much disordered, but highly 

 instructive headland has not yet received the attentive 

 study which it deserves. It has likewise been seriously 

 misrepresented, and its structure much misunderstood. 

 Part of a summer vacation spent there has opened out to 

 my view a series of most unexpected facts relative to the 

 geological history of this region. At Gay Head, especi- 

 ally, the writer was enabled to examine in considerable 

 detail the section back of the slipped clays, sands and 

 mixed materials which cover and disguise the face of 

 the bluff, and to recognize the formations in their actual 

 positions. The following statements will indicate thegeo. 

 logical series which exist there, and the order of their 

 superposition.
