“York, Pa., Dec. 24, 1852. 
“ Dear Sir The Dzierzon theory and the system of 
bee-management based thereon, were originally promul- 
gated hypothetically in the ‘Eichstadt Bienen-zeitung,’ 
or Bee-Journal, in 1 845, and at once arrested my attention. 
Subsequently, when in 1848 at the instance of the Prus- 
sian Government, the Rev. Mr. Dzierzon published his 
‘ Theory and Practice of Bee Culture,’ I imported a copy 
which reached me in 1849, and which I translated prior to 
January, 1850. Before the translation was completed I 
received a visit from my friend the Rev. Dr. Berg, of 
Philadelphia, and in the course of conversation on bee-

system as one which I regarded as new and very superior, 
though I had had no opportunity for testing it practically. 
In February following, when in Philadelphia, I left with 
him the translation in manuscript — up to which period I 
doubt whether any other person in this country had any 
knowledge of the Dzierzon theory ; except to Dr. Berg, I 
had never mentioned it to any one save in very general 
terms. 
“In September 1851, Dr. Berg" again visited York, and 
stated to me your investigations, discoveries and inven- 
tions. From the account Dr. Berg gave me, I felt assured 
that you had devised substantially the same system as that 
so successfully pursued by Mr. Dzierzon ; but how far 
your hive resembled his I was unable to judge from 
description alone. I inferred, however, several points of 
difference. The coincidence as to system, and the princi- 
ples on which it was evidently founded, struck me as 
exceedingly singular and interesting, because I felt confi- 
dent that you had no more knowledge of Mr. Dzierzon 
and his labors, before Dr. Berg mentioned him and his 
book to you, than Mr. Dzierzon had of you. These cir-
