The numbers represent the numbers of flocks, the total being 40. The percentages are the 

 percentages of barren ewes in the different flocks. The flocks are arranged in six divisions, 

 according to the methods of feeding, as explained in the text. 



Division E. — This includes flocks of Border Leicester and half-bred (Border 

 Leicester x Cheviot) ewes which were placed on better pasture during 

 tupping and for some time (usually about three weeks) before, but which 

 otherwise received no sort of special treatment ; in some instances, however, 

 the ewes received a limited number of turnips during pregnancy. 



Division F. — This division includes Border Leicester, and half-bred (and a 

 few Cheviot) ewes which were fed all the year round on grass, receiving no 

 special treatment of any kind. 



Table I shows very clearly that the percentage of lambs was, as a rule, 

 larger among flocks which underwent a process of artificial stimulation during 

 the sexual season, while Table III shows that the percentage of barren ewes 

 was generally relatively less in such flocks. The Cheviot and Black-faced 

 sheep in Division B which produced less than 100 lambs per 100 ewes 

 (Table I) are stated to have been unusually unprolific owing to their never
