40 PROCEEDINGS OP THE 



"There is, or used to lie, a large roost in the northern end of 

 Martic township, along the Susquehanna river, but I cannot 

 now give you information about it as I have never seen it." 



14. Mountville, Lancaster Co., Pa. 



Prof. H. Justin Rodd}' reports: "There is a very large Crow 

 roost near Mountville, Lancaster county, about four and a half 

 miles northwest of Millersville, and when I last visited it the 

 grove in which the Crows roost was black with the birds for 

 quite a distance. The area of the roosting grove was not less 

 than twenty-five or thirty acres, and all the available space on 

 the branches seemed taken up by the roosting birds. The point 

 is located about the center of an extensive farming region, com- 

 prising Lancaster county wholly and the eastern half of York 

 county. This causes the birds to flock towards it from all 

 points. The Crows, however, converge towards the roost along 

 probably four important radii, and of these the most important 

 line of flight was, and is yet, from the east or a little north of 

 east from the Welsh Mountains along the Neflsville hills — an 

 eastern extension of the Chiques hills. 



"In mid-winter, when the wind is high, the flight of the 

 Crows is very interesting; the birds screening themselves from 

 the wind by flying on the southeast side of the hills and their 

 crowning woodlands. The flight reaches Neffsville, five miles 

 northeast of Mountville, at about 3 p. m. on windj' days and at 

 about 4 p. m. on calm days. The morning flight along these 

 hills is not so well defined. 



"The flight from the north I used to watch from Elizabeth- 

 town, fifteen miles north of Mountville, and at one time, in 1882, 

 I counted 12,000 Crows passing over a hill near the town." 



15. Long Level, York Co., Pa. 



Mr. J. Jay Wisler writes : "In York county, from the post- 

 oflice known as Long Level, southward some eighteen or 

 twenty miles down the river and among the river hill.s in shel- 

 tered valleys, there are said to be a number of Crow roosts. I 

 have never had the opportunity to visit these roosts in the even- 

 ing, but I saw one of them in the middle of the day and of 

 course there were no birds there at that time, but from the drop- 

 pings there must have been large numbers of Crows roosting
