If the percentage of cream wasgreater than usual, it would show that the sample was light from unusual richness in when milk tests heavier than usual, if the cream diminishes as the gravity increases, skim-ming would be proved, but if the usual percentage of cream appeared in,the creamometer, itwould be considered certain that the unusual gravity was from some other cause thanskimming. It is not safe to dispense with the use of the cream test, even when the lacto-meter indicates pure milk, because it may be so easily cheated. The rogue who knows thatskimming milk makes it heavy and watering makes it light, may, after skimming, water. THE DAIRY. 241 his milk enougli to make it just as heavy as whole milk should be. The indications of thelactometer would show such milk to be pure, though it was both skimmed and watered, butan appeal to the cream-guage would det(jct the whole fraud. The indications of the lactometer are often objected to because the milk of individualcows show wide variations in specific gravity when tested with that instrument. Therewould be a good deal of force in these objections if the tests were confined to the milk ofsingle cows, for it is well known that there are cases in which the tests have shown deepskimming and as high as 16 per cent, dilution in milk as it came from healthy grass-fedcows. The utility of the lactometer in connection with the cream gauge is based upon theequally well known fact that, in the milk of a herd of any considerable nu
