15. Persian lamb fur.—From time immemorial breed- 
ers in Central Asia have raised a peculiar broad-tailed 
sheep which produce the Per- 
sian lamb fur of commerce. The 
original stock is known as Kar- 
akul, but near kin is the Arebi, 
which has been used in crossing 
to improve the luster and curl 
of the wool. Arebi lambs are 
black when born and have a 
tight, curled fur of wonderful 
luster. As the lambs grow the 
wool turns brown on the outside, but underneath remains 
black. A few Arebi have been imported to this country 
for crossing on Cheviots and Lincolns, the aim being to 
secure a product to take the place of the Persian lamb 
fur of Asia.
