Milk Supply Of City Excellent,
 Statement By (. Of (. Declares

cent butter fat and 11.25 per cent total solids the same as grade A In passing it might be noted that the standard for butter fat and total sol ids are those known as U. $. stan dards. The bacterial count for grade B milk, raw selected as sold direct to the consumer, has been set at 150,000 bacteria, except that during the period from May i to Oct. l, the number of bacteria permissible has been increased to 300,000.
 From 73 samples of market milk from six different cities of the Mid | dle West, the bacterial count varied | from 483,SS9 to 4, 57S,217. The stan | dards for the city of Phoenix, there | fore, show that a high standard has | been set. Tn the earlier years of regulating | | the milk supply, many obstacles had | to be met and overcome. Few dairy | men were equipped with milking i stables, or with milk houses. Proper ] sanitation requires that milk must be | | treated as a highly perishable food 1 I product. The cows must be healthy, 1 | the feed must be clean and free from mold or injurious matter. The water | must also be clean and pure, and convenient to the cows The milker and all who come in contact with the milk must be in | good health and be clean in person, and careful in their work. All uten- l sils must be clean and kept clean by | sterilizing. There are many other | details that must be watched, too many to mention, but each of which l is important.
 Tn the early days of dairying in the Salt River valley, the dairyman | mixed his cows in an open corral, l dumping the milk into cans and the milk was peddled directly from the open cans. That was a long time ago, and there has been much prog ress since. Retailing the milk in bot ties was one of the first steps. Other reforms have been brought about and | during the past few years especially, progress has been rapid until now the I people of Phoenix are assured of a milk supply that compares favor ably with the milk supply of any city | in the country.
 Building stables and milk houses installing pumps, coolers, refrigera- l tion plants or buying ice, costs mon ey, but the milk producers have re- sponded with a spirit that is com- mendable and are producing milk
 that is sold to the consumer cheaper than milk is sold in many cities
 throughout the United States.
 As an indication of the progress
 WHlcn mas been made Tn improve
 ment of the general milk supply, the
 following figures are Illuminating:
 .Grade A milk for the four summer
 months of 1918 showed an average butter fat contents of 3.44 per cent,
 total solids 1912 per cent. Bacterial
 count averaged 43,359.
 ''The grade B milk for the same
 period showed an average butter fat
 contents of 3.54 per cent, total solids srN<1. J...x% of 270,13S.
 Now compare these figures with
 1921 for the four summer months. The grade A milk average a butter
 fat content of 3.53 per cent, total
 solids 1920 per cent and a bacterial count of 25.491. The grade B showed
 an average butter content of 37S
 per cent, total solids 12S0 per cent ] and average bacterial count of 121,- } 972.
 Tt will be noted that all these l figures show a higher butter fat and solid content than is required. It , will also be noted that while the bac- , terial count for grade B milk, which is most in demand in the city of } Phoenix, in 1918 was close to the } limit of the number permitted, for the summer months of 1921 it was l lower than the number permissible 3 during any part of the year. I This we believe to be a remark l able showing and should be a matter : Of congratulation to the consumers in that they have a milk supply
 which is highly satisfactory. r To supply the retail trade of the
 city of Phoenix with milk and cream, I 1t requires the milk from 1249 cows : and 54 dairymen are engaged in this s work, Fourteen dairies have over 25 | cows and 16 dairies have under 10 f cows. Eight hundred and seventy f seven of the 1,249 cows are tuberculin
 tested. In other words, more than
 three fourths of the cows of all the P dairies supplying the city of Phoenix r are tuberculin free.
 . Housewives too often do not ap-
 preciate the efforts which the dairy
 men make to supply milk, to make
 deliveries on time. and in the best
 possible condition. As slight toker
 of this appreciation, the housewife
 can assist materially by being prompt
 in the matter of the return of the
 empty bottles and to see that they
 are returned clean. This matter o
 returning the bottles in Il clean ant
 sanitary condition is one which is re-
 quired by the city ordinance and i
 is a part of the milk inspectors du-
 ties to see that it is reasonably en-
 forced
 "All in all, the city of Phoenix ha.
 much to be proud of in its mil sup
 ply which is the result of hearty CO
 operation between the producers ana
