In the first category we have the Neufchâtel, the manufacture of which is extensive and profitable in the district of Bray; the Brie, the Pont l’Evêque, and the Camembert may be mentioned as examples of the second; Roquefort and Dutch of the third; and Gruyère and Parmesan of the fourth. There are defects to which even the best cheeses are commonly subject--defects, of the causes of which the professed cheese-makers themselves do not always give consistent accounts. Every good cheese should be of uniformly smooth surface, and perfectly firm; of colour unvarying throughout the whole surface, save only where the marks of age, necessary to certain kinds, appear. Softness and soapiness of texture; cracks, attributed by some to the action of lime on pasture, by others to the employment of too strong a draught in the process of drying; and holes, caused by “heaving” or “sweating,” are patent signs of imperfection which should warn the most careless purchaser against the cheese in which any of them are found. “Marbling,” the worst of all faults, is a mottled appearance of the surface, somewhat resembling the veining of marble. It is due to one or more of the following causes: not properly scalding the cheese; adding the colouring (which should be put in before the rennet) after the cheese has come; not properly squeezing out the whey. Wherever this occurs, it imparts to the cheese an exceeding ill flavour--in fact, makes it unfit to be eaten. It is especially dangerous in cheeses of the North Wilts kind, where the surface is invisible to the purchaser. Rankness of flavour, which can of course be guarded against by those who buy their own cheese, is also to be met with in the best kinds. This has been imputed to impurity of rennet; but, as it is frequently found in the cheeses of Scotland, where it is pretended that the greatest care is taken of the rennet, it may possibly also result from bad quality of pasture. In the Scotch dairy farms it is said to be obviated by pouring a very small quantity of saltpetre into the pail before milking the cows. Following are some remarks on the chief British cheeses, culled from the _Field_.
