It is now customary to ship cheese as soon as they cease to be curdy, which occurs in from ten to fifteen days from the hoop. EXPERIENCED HELP. One great set-back to good cheese making is inexperienced and careless labor. This is another cog in the wheel that has been retrograding the reputation of our goods during the last few years. A medical student cannot obtain a diploma authorizing him to take under his charge the welfare of the sick without three years’ study aided by ocular demonstrations of his especial science. Then, he is expected not to have a dim idea of a patient’s condition when diagnosing his case, but to know and understand all about it. No cheese maker is fit for duty unless he can diagnose the condition of a vat of milk on a quick examination. The natural odor of pure milk has a peculiar animal smell, whose nature can be acquired by careful olfactory tests indulged in as the student draws the fluid from the cow’s teats. After an apprentice at the business can tell pure, sweet, untainted milk in any spot or place, he must learn to distinguish between that which is tainted and that which is verging on the sour. Tainted milk is radically different from sour milk, and infused in the product they each tend toward utterly diverse results. To pass a correct judgment on milk quality is thus essential No. 1 in a maker’s practical knowledge. Requirement No. 2, is to have a thorough understanding of the constituents and influence of all of the foreign ingredients that go into cheese. Rennet, the most potent auxiliary of the cheese maker’s craft, should never be handled or applied by ignorant hands. The amateur maker should gain a physiological insight into the lactic portion of animal anatomy, and have an intelligent comprehension of the active force of the peptic secretion. When such knowledge is acquired he will see the importance of never countenancing any coagulating fluid that is not immaculately pure in extraction and free from any subsequent taint. He will also understand its nature enough to always make a judicious application of it to the milk designed for manufacture. Here the necessity of step No. 1 joining hands with No. 2 is apparent, for he cannot make a judicious application unless his olfactory sense is trained to perceive and gauge every variation of the milk quality. Necessity No. 3, is in following the quality variation of milk into the cooking and maturing curd. It is a well-known fact with cheese makers that no two vats of curd will scarcely ever work exactly alike in succession. If one is to know absolutely just what to do and what to leave undone at certain moments of assimilation and maturity in curd, he must have gained that knowledge not from books but from continued practical experience. Here the necessity for previous learning arises. No pettifogger would be expected to argue legal points before the Supreme Court, because lack of advancement in the rudiments of his
