WITH the advent of the season when ice is most in demand should also come an access of care and attention as to where the ice supplied to the community is bought. The various boards of health, we fear, take little, or no heed as to the source of supply, nor even pause to ask whence it comes or of what it is composed. A careful examination of some of the stuff that is delivered to their customers by the various ice dealers would show that not unfrequently it is full of impurities, while, if theinquiry were pushed far enough,it would be found that the water of which it was composed was contaminated with sewage, and full of disease-bearing microbes, which all the freezing in the world would not kill. It is a wellknown fact that typhoid epidemics have been traced to the use of ice cut from a river or pond whose water has been proved to be unwholesome; and that having already happened, there is no reason why it should not happen over and over again; unless due supervision is exercised both at the source of supply and in the cities and towns so supplied. And what is true of natural ice applies equally to artificial ice as furnished by the machine made ice companies. The water used in its manufacture is not unfrequently drawn from driven wells—a fact which is often more than sufficient to raise a suspicion as to its wholesomeness. The matter would bear investigation.
