In receiving either milk or cream from the patron, it is essential not only that justice be done in the weight or measure, but that the patron should be satisfied of this fact. The agent sent out to gather cream should be an honest man, in whom the patrons as well as the employer have confidence, and should understand his business and do it in a workman-like manner, so as to inspire confidence. He should also be versed in the various tricks that may be resorted to by patrons to deceive and cheat, and be on his guard, quick to discern any suspicious surroundings or indications. As much depends on his judgment and observation as on his honesty--especially if any of the patrons are disposed to be dishonest, as is sometimes the case where it would generally be least suspected. The later device of not only measuring cream by the gauge, but of testing its yield of butter by churning a sample, is not only a guard, to considerable extent, against fraud, but more closely approximates justice by getting at the actual quality of the cream, on which depends its value. There is no associated system yet devised--save that of churning every patron's cream separately and weighing the product--that secures exact justice to all. Nature does not appear to have furnished standards of commercial measure or value for the purpose of indicating mine and thine in mixed transactions, or in speculative exchange. We have only relative and approximate guides, by which justice, in a business sense, is by no means secured. TESTING.
