 Rauchfuss Brothers, Denver, Colorado, imported queens of 

 this race and recommended them. Following this, addi-

 distributed by the United States Department of Agriculture 

 several years ago. 



The gentleness of this race is universally admitted, but 

 Caucasians have some faults which have caused them to be 

 abandoned by most beekeepers who have tried them. They

 This has virtually necessitated the use of ItaUan bees in 

 many localities and has discouraged experimentation with 

 other races. There are still several prominent beekeepers 

 who are enthusiastic in their praise of the Caucasians.

This is the most popular race of bees among the best 

 American beekeepers. The bees of Italy vary considerably 

 in color, those in the north of the country being virtually
