In the first place it is to be remark'd, that some Grounds will never produce good Butter, and others will not produce good Cheese, tho' there is the best management in the Dairy. Again, there is one sort of Cattle, which tho' we feed them in the finest Grass, and best Pasture, will never yield a rich Milk; while on the other hand, there are some sorts of Cattle which will yield a rich Milk for Butter in any Pasture: tho', as I have observ'd before, the Milk and Butter will be ill tasted if the Cows fed upon Crow-Garlick, Alliaria, or Saxifrage. What I have said of this, with regard to the making of Cheese, must here be consider'd; that is, if the Cows feed upon short fine Grass, there will be more Cream in the Milk than if they feed upon long rank Grass. Indeed the long rank Grass will give more Milk than the short, but less Butter, and worse into the bargain. Again, the Milk of one Cow shall give richer and better Butter than the Milk of others, tho' they all feed on the same Pasture, even so that the Milk of one Cow will cover or enrich the Butter made from nine or ten other Cows; her Milk will make Butter of a rich yellow Colour, full of Fatness, and the others will only produce a pale, lean Butter, but all together will be good: I know several Instances of this, and every one who is skilful in a Dairy may observe it. I have already treated largely concerning this Particular, in my Works of Husbandry, and I shall therefore proceed to speak of the Management of Milk in the Dairy for making Butter; for I am very sensible, that many Farmers might have twice the Benefit from their Dairies, if the Articles of Butter and Cheese were consider'd in a rational way, and the old Custom could be broke through; and moreover, if the best Rules for managing of the Dairy were known, and put in practice, the whole Country would be the better for it, every one might enjoy the benefit of good things: whereas for want of knowledge among some Farmers, their Goods are of small value, and the People are also disatisfied.
