10 PEOCEEDINGS OF THE 



esting and unusual ornithological occurrence, in the Martin 

 colony which is established in the very center of the town, 

 large numbers of birds occupying boxes which have been 

 placed on trees and buildings on the busiest street corners 

 where traffic is heaviest. They are from seven to fifteen feet 

 from the ground and the birds dart in and out over the heads of 

 pedestrians or hotel visitors resting in chairs along the side 

 walk. 



Here too we met Mr. G. Fred Ziegler, Jr. a local ornithologist 

 who the next morning conducted us to favorite spots about the 

 town in search of birds; but woodland being scarce in this broad 

 cultivated valley, we did not secure a large list. From Green- 

 castle we went to Mercersburg, stopping en route along the Con- 

 ococheague Creek where Baily found a Rose-breasted Grosbeak 

 and Street saw a pair of Blue Grosbeaks. 



We then proceeded to Foltz which is located among well 

 wooded hills and by far the most attractive bird country we 

 have encountered since leaving Jack's Mountain. Down on 

 the banks of Buck Run is a rough stone monument marking 

 the birthplace of James Buchanan, President of the United

 that a deciduous forest. Here we could hear at one time the 

 songs of the Black-throated Green Warbler, the Hooded, Ken- 

 tucky, Chat and Louisiana Water-Thrush, a curious interming- 

 ling of northern and southern forms. The elevation was from 

 900 to 1000 feet. 



We then turned our course northeast and skirted the foot of 

 the mountains all the way to Fort Loudon where we arrived 

 late in the afternoon. After supper, we walked back to Rocky 

 Hollow Ravine behind the village and here in the gathering 

 dusk we heard our first Whip-poor-will of the trip, which was 

 Joined by others until a whole chorus of them was singing 

 all about us, while a Grouse boomed from the opposite moun- 

 tain side and far up above came the cry of a Great Horned Owl, 

 which was answered by a farm laborer who soon after came up 

 to us and informed us that he and the owl frequently commu- 

 nicated in this way in the evening. 



Immediately opposite the village rose Jordan's Knob a steep
