APPENDIX B 



The following instance of the perseverance with which a 

 bird will, at times, cling to the spot selected for a nest in the 

 face of what might be supposed insuperable difficulties is 

 given as told by a careful and patient observer of nature, who 

 has himself succeeded in taming free Swallows, and inducing 

 them to feed their nestlings on his lap.
