Phoebe (Say's ?) in which a bee's sting was found in the base of 

 the tongue. 



The birds were all shot about apiaries and were seen darting 

 upon and catching the bees. The examinations were made with a 

 hand lens. Mr. Barnett regards the occurrence of the sting 

 found in the Phoebe as accidental and concludes that Flycatchers 

 are beneficial in reducing the number of drones.

Since the foregoing notes were written I have received an 

 excellent and timely work by Dr. A. K. Fisher on The Hawks 

 and Owls of the United States in their Relation to Agriculture, 

 and which in itself is so complete and conclusive that I may 

 withdraw the meagre notes which I have made upon rapacious 

 birds; they only confirm the conclusions of Dr. Fisher that most 

 of the hawks and owls are far more beneficial than injurious to 

 the agricultural interests of the countrj'. The microscopical 

 examinations, so far as I made, of the contents of the stomachs 

 of the small land birds of California, are vastly in favor of the 

 desirability of protecting them all. A few local instances where 

 actual damage has been done, notably in fruit orchards, must 

 not be taken as a criterion of the value of the species throughout 

 the State and throughout the entire year.

BY O. P. JENKINS. 



The necessity for seaside laboratories for advancement in bio- 

 logical science has been thoroughly discussed and practically 

 settled. 



In Europe the conclusions of this discussion have been more 

 extensively accepted and acted upon than in this country. 

 Within the past twenty years a large number of such stations 

 have been established on the coasts of the various countries of 

 Europe. Of all these the most famous on account of its mag- 

 nificent equipment both in appliances and in a very complete 

 library, as well as for the grand results which have followed its
