European Bison

again enjoyed more prosperous times, and began rapidly to increase. As 

 early as the winter of 1821 it is stated, for instance, that the number of 

 head of all ages totalled over 700 ; while in December 1828 Eichwald 

 estimated the number in Bielowitza at 696. In addition to this, from 

 thirty to forty head were at the same time living in the forests of Count 

 Tyschkiewictz. In 1829 the number was set down at 711, of which 663 

 were adult and 48 young animals ; and in the following year the herd was 

 variously estimated at from 700 to 772 head. Eichwald, who is the 

 authority for the latter number, further states that during the first Polish 

 revolution of 1831, the herd lost 115 head, thus reducing its number 

 to 657. 



Some error seems, however, undoubtedly to exist with regard to this 

 number, since the first of the regular ot^cial counts, which took place in 

 1832, gives the total number of bison at that time as no less than 770, of 

 which 712 were adult, and the remainder young. Since that date till 1872, 

 with the omission of certain years, the numbers are tabulated as follows,
