Before using th germ-food, however, one hundred ers of water are measured into e-flask. Then one-tenth of a ter of milk is sucked up by a glass pipette, which is not unlike a straw, and dropped into the water. Ti makes a proportion of one of milk to one thousand of water and is known as dilution process. Another pipette is used to suck up one centimeter of the mixture of milk and water, and this is dropped into a tube of liquefied agar-agar and imme- diately plated out into a Petrie dish—a shallow glass with a cover. This dish 1 en set in an Incubator for about six hours at a temperature of centigrade, which is equivalent to Fahrenheit. This heat, together nourishing property of the has a tendency to make the col- grow and the plate clearly shows bacteria, which resemble white specks to the naked eye. This dish is placed on a Wolfoegel tablet, which is a glass marked off in one-fourth-inch squares, to enable a better count of the nies through a powerful micro- secop. Some samples show as many as 1,800,- 000 colonies to the cubic centimeter. This is a sign of a dirty dairy. Boston has a bacterfa standard of 500,000 colo- nies to the cubic centimeter and when- ever it goes above that figure drastic measures are taken against the daliry supplying the milk. Unfortunately, the Board of Supervisors have not seen fit to enact the Board of Health's recom- mendation of an alike standard into an ordinance, and therefore the health authorities of this city may only ad- monish cleaner methods. It is the presence of bacteria in milk that causes Samples of milk wnd then the thimble, with the ab- sorbent paper containing milk, Is placed in the Soxhlet apparatus and the fat is extracted by means of ether.

Now, while the bacteriologist is look- ing for germs, the chemist is busily en- gaged searching for preservalines, sol- ids, etc., and arriving at the correct amount of butter fat in the milk. The standard of butter fat a vear ago was 3.2, and through the efforts of {he Health Department this standard was raised to 3.4, thus insuring the 'best quality of milk to householders. If the butter fat fails below the standard the dairyman is.arrested and he is usually subjected to a fine by the police magis- trate. It may not be am to dwell on the process followed by the pure food laboratory in arriving at the informa- tion degired. b TWhen the sample is brought in its specific gravity is taken to find out it it comes up to the standard for total solids. Then 17.6 cubic, centimeters of milk are placed into a Babcock bottle, mixed with an equal volume of sul- phuric acid, and. this is placed in the Still Angthe AN and woman both have been created by God. Both should have the same privi- leges, the same liberty, the same treatment and the chance of getting the same kind of po- sition in every affair—political, social or religious. . Man has the soul just the same as the woman. Why then should man possess more liberty and have more privileges than woman? There can be no distinction between a mans soul and that of a woman. Why then should the soul have more privileges at one place and less at another? This is something llke the caste system of our forefathers. The squl can have no caste, no sex, no distinction whatso- ever. ‘When you give liberty to people in every respect, 4o you give it to their external and material body, which is perishable, or do you give it for the advancement or evolution of the spirit within?

Every sample, therefore, receives frem six to eight special tests, besides the ordinary tests for butter fats, be- fore it is pronounced fit for human con- sumption. It is thus that the milk dealers are forced to dispense good milk to this =ity. In the ear}y hours of the morn- ing milk is delfvered and inspectors are on the lookout for the vehicles carrying the lacteal fluld. The wagon is halted and a sample is taken from a full can and sealed in the presence of the driver. ' A sample from the same can is also sealed and turned over to the driver, who turns it over to his employer. This permits the owner to have the milk examined by a private chemist in the hope of dis- proving the anaylsis of the Health De- partment’s experts. This, however, proves futile, as the Babcock and’ Soxhlet tests are perfect apd the tese timony of the- Health Department's representatives is given great consid- eration by the police magistrates. Last month inspectors were sent to the rés- taurants of this city and samples were 1 t men, who had been in the it of watering their milk or serv- ing' their .patrons with the skimmed article, were arrested and heavily .fined. This has had a salutary effect on the dispensers of the fluld and they are giving .the public the price of their money, as they fear another visit from the health authorities. No one can seil .milk ia this city without, a permit from the Board of Health, and those who possess the permit must exercise great care in the handling of the article of food, for fear of having the permit revoked. Again, close watch is kept on. the dalry depots of this city. Almost half the dealers and dispensers of milk have no dairy farm and rely on thetr milk supply from outside sources. The depots must be kept clean and oper- ated in harmony with the ordinances of the city and county, otherwise they will be subject.to vacation proceed- ings. This means, of course, the clos- ing up of the depot. The Health Officer has forced the dairymen outside the county to' also comply: with -the ordinance. Ian or< “der to reach thess milk producers it Was necessary to inspect their ranches and whera they were found to he in a filthy condition ot d!d mot comte up to the requirements of the ordinances the depots handling the milk’ffom these places were notified that l! their ;h!v- vers dfd not ‘clean up the milk" sent into this cify would be quarantined and their permit to dispense it would be revoked. > Residents of this city may rest as- sured that the milk supply of this city will be of high standard, as the Board of Health is on the alert and every effort will be Made to force dairymen to live up to the ordinances. In-an article on “The Sources, Ef- fects and Prevention of Dirty Milk" written® by “that eminent aulhority, Charles Harrington, M. D., professor of hygiene at Harvard University and head of the Boston pure food labora- tory, the- author says: “When we speak of dirty milk we mean mlilk which, largely by, reason of the admission of preventahble dirt, but. equally, or even more, in conse- quence of improper methods of-cool- ing, handling and storage, contains ex- cessive numbers of bacteria.” The pre- ventable dirt gains access in varfous ways. It is derived chiefly frem the body of the cow and.consists largely of. halrs and particles of excrement. \A single hair may contribute hundreds and thousands of bacteria to the milk- ing pail, and the number of hairs which may be dislodged from . the -parts immediately above the pail" dur- ing the process of milking. through the necessary manipulation of the udder and the contact of v?e person of the milker, is very grea In the same way, and through itching of the tail, particles of excrement, ladem with bacteria, fall in a constant shower into the pail. It has been calculated that under ordinary- conditions of handling and storage the presence of abeut a twelfth of a grain of such.dirt per quart will cause each cubic centimeter of the milk to yield nearly three and a half millions of bacteria by the time it 1s delivered to ths customer, and Back- haus has reckoned the amount of cow excrement that the population of Ber- lin consumes dally with its milk at about 300 pounds.”™ Another important item is the care of the dairy herd. Drs. Hassler and Brady are capable veterinarians and in the course of imspection of dairies they invariably examine the cows. If a cow shows the least sign of being tubercular she is quarantined in am isolated spot for at least thirty days and subjected to the tuberculin test. If found to be afflicted the animal is killed and the carcass is coal-olled so that "‘the meat may not be sold fom food. Not more than three months ago samples of lce cream were secured from all parts of the city and tested for preservatives and In almost every instance the tpst showed the presence of gelatine, barax or thickener. Many were arrested, but no convictions were had, ‘because the dealers in fce cream informed the Judge that they bought the cream from a certain dairy and were paying for “pure, cream.”™ The dairyman was also arrested, but se- cured ihis release because the“State laws wére inadequate to cover the of- fense charged.
