BIOGRAPHY OF BEE-KEEPEKS. 223 



Zeitung, for May 1852. It has been adopted as the standard hive by 

 the Italian bee-keepers. 



Being a man of wealth and leisure he gave much attention to his 

 favorite subject. His last book on bee culture is said to be one of the 

 most complete ever written. 



He invited Captain T. E. Von Siebold, professor of zoology and 

 anatomy in the University of Munich, to his apiary to test by experiment 

 the theories of Dzierzon, and especially those connected with the par- 

 thenogenesis of the queen. He found on examination that the parts ad- 

 hering to a young queen returning to her hive from her bridal 

 tour were identical with the male organs of the drone ; that the 

 spermatheca of the queen was filled with the seminal fluid 

 of the drone, and that worker eggs were accompanied with 

 spermatozoa. Prof. Leuckart, at the request of Baron Berlepsch 

 dissected a drone laying queen, and found no semen in the spematheca, 

 In 1852 Dr. Jos. Leidy, of Philadelphia, dissected a queen for Mr. 

 Langstroth, with the same results as with Siebold. These two facts 

 prove the correctness of Dzierzon's theory, since eggs of unfertilized 

 queens do undoubtedly hatch and produce drones. 



In closing this sketch we must not omit to mention the German apiar- 

 ian Von Hrushka, the inventor of the Honey Extractor, to which we are, 

 in American bee-keeping, so greatly indebted. In the apiary it is second 

 to none of the important discoveries, in practical utility. 



Few men have taken a deeper interest in the pioneer work of bee- 

 culture than Mr. W. W. Oary, of Colerain, Massachusetts. About the 

 year 1850 he made the acquaintance of Mr. Langstroth, then living at 

 Greenfield, Mass, aud spent some time with him experimenting with 

 hives and bees. The greatest confidence and friendship has always ex- 

 isted between them. Hearing in 1860 of the successful importation of
