bees are of the greatest use; next come butterflies and moths, 

 while flies even do their share of the work, but it is more especially 

 the hive-bee that is the blossoms' partner by carrying the pollen 

 from one flower to another. 



That bees are useful to the tarmer even with ordinary farm 

 crops, and that some farmers realise this, is proved by the fact 

 that hives of bees are carried into bean fields just after horse- 

 hoeing, when the plants are about to bloom, that the bees may 

 be close to the crop to carry out the work of fertilisation.

 Adam and Charles Black, 1910. Reviewed in Nature, Au- 

 gust u, 1910, vol. 84. 



This book is almost entirely devoted to the salmon of the Tay, 

 sea-trout, and brown trout. 



'< The other fresh-water fish are but slighly dealt with and the 

 chapters allocated to them call for no particular notice.
