it IS yet to be seen to what extent they should be introduced into 

 countries where improved breeds are widely distributed (Pig. 146). 

 Distribution.— Several countries have recently become inter- 

 ested m the Ivaralvul on account of the value of the skins of the young 

 lambs. Large numbers have not been brought into the United 

 States because of the long distance from Bokhara, and other diffi-

breds cannot be large. The pure-bred rams have been ci'ossed with 

 the well-known breeds of sheep, such as the Merino, Cheviot, Lin-

 have been obtained by crossing with the long-wool breeds producing 

 luster wools, and the poorest with the Merino cross. Just how 

 valuable the crosses and grades are as breeding animals has not 

 yet been definitely determined. It seems, however, that half or 

 three-quarter blood rams, when crossed upon ewes containing no 

 Karakul blood, are of little or no value as sires of fur-bearing lambs.
