 It was seldom that I did not take or note something of in-

 a shrike. When alarmed they flew higher and higher among 

 the branches of a tall pine, so that only the female was cap- 

 tured. Having never before seen this bird in a wild state, 

 I regretted the act which, in compliance with strict scientific 

 requirements, deprived that sea bound spot of so much 

 sweet music.
