428 Juurnal of Agriculture, Victoria. [10 Jtly, 1918. 



The dam of 2.103205 was by 7.492, wliicli, as already referred to, 



appears so frequently in unsound lines. 

 The dam of 2.103206 was by 7.34, of tainted line. 

 The dam of 2.103207 was by 6.2, of tainted line. 

 The dam of 2.1032005 was by 7.492, of tainted line (already 



referred to). 



A branch of the family which appears an unsound one is 2.1034 

 and his descendants. He was not examined, but he left 3 unsound 

 stallions out of 5 examined, and the dams of these three were as 

 follows : — 



2.10342 was out of a mare by 1.13, a very unsound horse. 



2.10343 was out of a mare by 1.1, the sire of a very unsound 

 family. 



2.10344 was out of a mare by 7.231, an unsound line. 

 In the same generation, we find: — 



2.1030031 out of a mare by 2.1032, the granddam by a son of 11. 



2.1030032 out of a mare probably by 1.211, which was without 

 doubt unsound. 



2.1030037 out of a mare by 22.2, of unsound family. 



2.1030039 out of a mare by 9.521, which left 21 per cent, imsound. 



2.10300305 out of a mare by 6.15, of tainted family, granddam 



by 9.521. 

 2.1030071 out of a mare by a brother of 1.1, an unsound horse. 



2.10300051 out of a mare by 4.127, unsound blood, granddam by 

 a son of 3. 



2.10300052 out of a mare by 6, a tainted line. 



Stallion 2.10302 requires more than passing notice. He was by a 

 son of 22, from whom he, no doubt, inherited the unsoundness detected 

 when he was an aged horse. However, it must be noted that the 

 unsoundness was not pronounced. Eight of his progeny were examined, 

 and it appears strange that no unsoundness was detected in any of them. 

 It is unfortunate that the full pedigrees of the dams of these horses are 

 not available; but, from the particulars available, it appears likely that 

 the tendency to develop sidebones was not pronounced. Unsoundness 

 will probably be found in some of them at a later date. Two of the sons, 

 2.103021 and 2.103023, were full brothers, but of blood not recorded, 

 and of which nothing is known. It is probable that the dam was 

 particularly sound. 2.103025, only 3 years at examination, is a horse 

 in which unsoundness might be expected at an early date, as his dam is 

 by 3.102, an unsound horse. 



The number of the remaining members of the family 2.1 is insuffi- 

 cient upon which to base criticism. 



2.2 is badly tainted with unsoundness. One son and seven grandsons 

 are affected with sidebone; while seven grandsons and seven great- 

 grandsons are sound. 



2.2105, which was over twelve years of age at examination, was sound, 

 although by an unsound horse. His dam must have been a horse of 

 good age when he was born, as her sire was by the grandsire of 2.5, 

 shown in the opening table of this family. Evidently, she Avas particu- 

 larly soimd, or some trace of sidebone would have appeared in 2.2105.
