The rock is crushed, washed, sorted out by hand, to remove the foreign substances, then ground and subjected to acids, and at the end of the process it is as white and fine as the best bolted flour. This heavy adulterant is shipped to the North in large quantities, the manager said he had recently an order for a hundred thousand dollars' worth of it. What is the use of this powder?

It is doubtful if an adulterated sugar can be found in the United States, notwithstanding the tales of the grocer who "sands" his sugar, and of the producer who adds terra alba or some other adulterant.
The production is a Government monopoly, and I believe that if care is taken to secure flasks of attar with the Government seal the purchaser may be sure of getting the genuine article. Otherwise, as likely as not, oil of geraniums is substituted for the attar of roses, or is used as an adulterant.
Reclaimed rubber is not to be considered as an adulterant, except in the same sense as fillings, like whiting, litharge or barytes, the use of which in rubber compounds often gives to the product desirable qualities that are unobtainable by the use of "pure gum."

Potato flour is the waste of potato after the starch and alcohol have been extracted; it has no more food value than so much wood, and as its use as a food adulterant is a penal offense in Europe, thousands of tons of it are shipped to America every year. It was amazing what quantities of food such as this were needed every day, by eleven hungry persons.
A very good and simple way to test for such adulterations is to take up a quantity of the oil in a test tube with a solution of borax and water. If there is any animal or vegetable adulterant present it will appear as a white milk-like emulsion which will separate out when allowed to stand.
