 PURE MILK.


 Method of MT. Straus-Guarding the Sources of Supply-How Cleanliness is Guaranteed
 The question of a pure milk supply for great city is one that always pos
 sesses popular interest; but the revela-
 tions made during the last few months
 of the deleterious effects of some of the means resorted to by dairymen and
 milk dealers to keep milk from spelling
 have brought the matter into eXcep- tlonal prominence of late.
 It is due to the New York board of health to say that its system of inspec- tion, both when the milk is brought into town wholesale and while it is be- ing retatled from the shops, is so thor ough that there is little chance for the sale of lacteal fluid with disease germs Tn it, or diluted with an excessive amount of water, or "doctored" with such preservatives as salicylic acid, boric acid and formaldehyde But the possibility of accidental deterioration after the milk has once been examined and the lack of care on the part of many dairymen who send milk to the metropolis have created enough uneasi- ness in the public mind to render ad- ditional unofficial precautions desirable, if not necessary. These precautions take the form of such treatment of the milk after it arrives as will keep it free from disease germs and the em- ployment of safeguards of a preven- tive nature before the milk gets here at all
 It has long been known that mere boiling of milk would kill bacteria in it. This is the simplest mode of disin- fecting milk. And what is generally sold as ''sterilized" milk has been heated to a temperature closely ap- preaching or fully attaining two hun dred and twelve degrees Fahrenheit The corporation that does business un- der the name of the Sterliized Milk company employs patented process, invented by one Appleberg; and those who control it are chary about impart- ing information on the subject. How ever, except in certain details there is no secret in the system
 "Pasteurized" milk is also rendered safe by means of heat, but the temper ature developed is not quite so high as in the ordinary sterilizing process Even here there is a slight diversity of practice, some operators never going above one hundred and fifty degrees Fahrenheit others reaching one hun dred and sixty-seven-Paste steurs own practice-and still others using a yet higher temperature.
 At the Straus headquarters in Avenue c the following routine is observed The milk, having been kept in a cool room from it's delivery at or a. m. until o'clock, is first cleaned by ap- paratus resembling the Separator of a dairy. By centrifugal force all solid particles are thrown out of the fluid but without effecting a divorce between the cream and milk The milk ie next drawn off into small bottles, usually viously been washed with antiseptic so- lutions. Rubber corks are now insert ed The shoppers each have a groove reaching part of the way up on one side; and at first they are put in rath- ', ar loosely, so that when the bottles are 1 heated provision is made for the ex- pansion of the contents.
 The bottles are set upright in light | metal frames or carriers and lowered | nto copper boilers resembling ordinary wash boilers The carriers are com posed of a dozen cylindrical vessels, ,ach a trifie larger than bottle, and a wall of cool water surrounds each bot le when it is first placed in the center
