FROM THE GAME FIELDS.

These additions would make the total 

 protein 1.190 pounds and the total fuel 

 value 14,377 calories for 4 persons, or for 

 one person, 0.298 pound protein and 3,599 

 calories. For the sake of simplifying cal- 

 culation, no distinction is made between 

 the amounts required by men and women. 

 These values are approximately the 

 amounts required by the dietary standard. 



Following the above method, the value 

 of any diet chosen may be easily calcu- 

 lated. It should be borne in mind that ap- 

 proximate rather than absolute agreement 

 with the dietary standard is sought. It is 

 not the purpose to furnish a prescription 

 for definite amounts of food materials, but 

 rather to supply the means of judging- 

 whether the food habits of families accord 

 in general with what research has shown 

 to be most desirable from a physiological 

 standpoint. If economy is necessary, a 

 study of the tables showing the composi- 

 tion of different goods will show that it is 

 possible to devise menus which will fur- 

 nish the requisite amounts of nutrients and 

 energy at comparatively low cost. 



THE IMPORTANCE OF PURE ICE. 



Many families are careful to boil or 

 filter the water which they drink, but it 

 not infrequently happens that ice will be 

 added to the water to cool it without the 

 fact being recognized that the ice may be 

 more impure than the water before filter- 

 ing. It is possible in many cities to pur- 

 chase artificial ice frozen from distilled 

 water. Such ice, if properly made, should 

 be free from disease germs and dirt. The 

 idea is widespread that freezing kills dis- 

 ease germs. As far as experiments show, 

 this is not the case. The micro-organisms 

 tested have resisted the lowest tempera- 

 ture it was possible to obtain. It is prob- 

 ably true that the water in rivers and lakes 

 is frequently purer in the winter than in 

 the summer, owing to the fact that the 

 small tributary streams which are often 

 the sources of pollution are frozen some 

 time before the ice forms in the large body 

 of water. An order was recently passed 

 by the Boston aldermen authorizing the 

 board of health to employ an expert chem- 

 ist to analyze the ice supply of the city, for 

 the purpose of ascertaining its purity. 

 The Sanitarian quotes the following state- 

 ments regarding this matter: 



"The city and State authorities are kept 

 busy with the problem of restricting pol- 

 lution, and even with the most careful su- 

 pervision our streams are badly contami- 

 nated. What, then, can be said of our ice 

 crops, where no supervision is had, much 

 less required by the owners? Did you 



ever hear of an ice company troubling it- 

 self to prohibit or prosecute offenders for 

 polluting their grounds? Have you ever 

 observed the general condition of an ice 

 plant bordering on a lake or pond? If so, 

 have you not seen the most dilapidated 

 buildings and surroundings? There is 

 neither paint nor cleanliness. The whole 

 has more the appearance of a garbage 

 plant than anything else ; but paint and 

 cleanliness cost money, and would there- 

 fore deduct from the profits of the trust, 

 and, what is more, the consumer as a rule 

 does not see them, so what does it matter? 



"The direct or indirect pollution of wa- 

 ter which sewage or other human or ani- 

 mal waste causes must be condemned if 

 we would avoid the possibility of distrib- 

 uting disease by the use of ice which 

 comes from such sources. Ice, which is 

 water in its solid form, has become an 

 important factor in the well-being , of man- 

 kind, and is absolutely essential to his wel- 

 fare today. Ice fields and crops are se- 

 lected solely because of their cheapness for 

 production, with little or no heed as to 

 their sanitary conditions ; and this busi- 

 ness is unrestricted and unmolested in its 

 conduct, notwithstanding it can and prob- 

 ably does convey more disease than any 

 and all other sources. This country har- 

 vests $100,000,000 worth of ice a year. Its 

 product is greater than the combined out- 

 put of gold and silver of the country, and 

 such a business needs some supervision 

 and regulation. ..." 



Like action by the aldermen of other 

 cities besides Boston, or, in default of 

 such action, by the health authorities, 

 would doubtless go far toward preventing 

 the spread of typhoid fever and other wa- 

 ter and ice born disease germs during 

 summer.
