In this scheme is shewn how impossible it seems to in- 

 tensify the mother's blood, unless all the mothers are 

 whole sisters. — Not being sisters, and assuming that you 

 must each generation take a young ram from a different 

 mother, which virtually must be the case, as you cannot 

 suppose one ewe always to produce ram-lambs, nor, if she 

 did, can you suppose them always fitted for the stud. 

 Suppose, however, this to be the case, and that the ewe h 

 had a grandson by her son, and a great-grandson by her 

 grandson, then it would show thus with the other ewes :—

Either all the ewes must be sisters, or you must find a ewd 

 who always breeds ram lambs.
