634 ANNUAL. REPORT OF THE Off. Doc. 



In the service of milk by bucket, the milk can and milk bucket are 

 of necessity opened every few moments to this contamination. In 

 wet weather the conditions are nearly as unsatisfactory, for the milk 

 is continually exposed to the dripping from the habiliments and 

 hands of the deliveryman. The service of milk in bottles wholly 

 overcomes these most serious defects. 



Again, in the house of the consumer the milk bottle is most ser 

 viceable. There is no hurrying around for a clean vessel when the 

 milkman rings at the door. The milk has no exposure to the atmos 

 phere of the kitchen or cellar. In the refrigerator the odors of 

 other foods are not imparted to the milk. As the milk is served in 

 pints or quarts, only so much of the daily output as may be needed 

 from time to time is required to be opened. This is a most im 

 porlant advantage in the case of infant's milk. With the bottlf 

 system the consumer may readily note the quality and cleanliness 

 of the milk. The cream, too, is equally distributed to customers; 

 also, if desired, the cream may be removed for immediate use, upon 

 the delivery of the milk. 



From a trade standpoint also there are advantages in the use of 

 the bottle system. The measurement of the milk is uniform. It is 

 easy to take reckoning of the amount that goes out on the wagons, 

 and the quantity returned. The deliveryman can put out double 

 the quantity of milk in a given time by the use of bottles than can 

 be served from the bucket. 



A theory has been advanced of late that milk bottles may convey 

 disease from house to house. We believe this has occasioned ground- 

 less fears. We have never seen proof of contagion being thus 

 spread, and we never expect to, for the following reasons: First, 

 how rare must be the instances in which the milk bottle is taken 

 into the sick room; everyone knows that milk must be kept where 

 it will be cool as possible; secondly, the surface of the bottle is 

 so hard, and so great its freedom from points of lodgment, that any 

 germs which may have rested in the milk-coated bottle would surely 

 be removed during the washing, the rinsing, and the scalding in- 

 cident to the cleansing thereof. 



Such are the manifest advantages attending the delivery of milk 

 in bottles that we anticipate the day is not far distant when any 

 other system of delivery will have passed into history. 



QUESTION. 



By JOHN C. LKWIS, City Forester and Landscape Gardener. 



"WHAT ARE THE FOUR BEST VARIETIES OF SHADE TREES FOR CITY 

 PLANTING, AND WHY ARE THEY THE BEST?" 



Presuming the inference of the question to be the four best va 

 rieties of trees for planting on city streets, will name the following, 

 which in my opinion, and according to my experience, are the best: 



Sugar Maple — Acer Saccharinum.
