92 STATES OP THE RIVER PLATE. 



during the heat of the day, a bite of green fodder will be 

 equally grateful to them at that time. The ' high-caste ' 

 breeder is amply repaid for these attentions to the com- 

 fort and requirements of his stock, as he wiU have little 

 sickness and a much higher development in his animals. 



The dfferent requirements of young and mature animals 

 in their food-matters, is also a point of mark with the 

 ' high-caste,' or, indeed, any breeder. In the young and 

 growing animal ' construction ' bears a much greater pro- 

 portion to the waste than in mature animajs. There is a 

 quicker circulation, and a more rapid oxidation is needed. 

 The albuminous compounds of the food are required to 

 be in a condition easily and speedily assimilable ; and 

 there is required, to meet the rapid oxidation of the 

 blood, that predominance of the saccharine element which 

 exists in green, succulent herbage over that which is 

 passing into ripeness and seed ; and, more especially, that 

 which is over-ripe, and from which the saccharine and 

 alkaline elements have, in a great measure, departed, and 

 in which the woody-fibres — the non-digestible matters — 

 prevail. 



The action of ' good feeding ' on the wool can also be 

 understood by a reference to the foregoing tables ; for we 

 see in the ' ashes ' of wool the minerals of the food which 

 the animal eats, and in the ' substance,' a very high pro- 

 portion of nitrogenous and sulphurous compounds.

I will now proceed to make a few remarks and sugges- 

 tions on important points in management. 



The selection of the most desirable season of the year 

 for the lambing must be determined by the more or less
