Another source of polluted air is the cellars of a great proportion of the houses. Of course the families living in the several flats of each building are all dependent upon one cellar, which is divided off into compartments according to the number of stories in the house. These compartments, however, are in many instances separated from each other by a mere partition of laths or rough boards, so that any want of cleanliness on the part of an individual house-keeper is sure to disturb all her neighbors. Owing to the custom of allowing small shops to be kept in the ground-floor of dwelling-houses there is apt to be a mingling of articles for storage in the cellar such as is neither agreeable nor wholesome. Thus, for instance, a dairywoman will fill the shelves of her compartment with pans of milk: her next neighbor is perhaps a small dealer in wood, coal and turf, and raises a dust accordingly; the greengrocer opposite makes the air damp and bitter with his heaps of neglected vegetables; while the butcher not only has a right to hang up his newly-slaughtered animals and chop his sausage-meat inside of his particular compartment, but may allow a living pig or calf, whose death-hour has not yet arrived, to roam up and down the dark passages, to the increase of the general dirt and discomfort. In this connection it may be well to enter a protest against the Munich regulation, or absence of regulation, which allows every butcher to slaughter pigs, calves and sheep upon his own premises. To say nothing of the shocking sights and sounds which are thereby forced upon the attention of the dwellers in the neighborhood of such shops, it is impossible, considering the defective drainage and insufficient water supply, that the practice should not be of serious injury to the public health. There are also many cellars which are rented out entirely to fruiterers and green-grocers not living in the buildings as a place to store their goods for the winter. In such cases the cellars are apt to remain in a filthy condition, and the smells that pour from the windows are at once a nuisance to passers-by and a source of danger to the inhabitants of the houses. But it is not only the living inhabitants of Munich that are corrupting the heavens above, the earth beneath and the waters under the earth: the dead in their graves are busy at the same work. It is a pity that all thinking persons who still object to the practice of cremation as unnecessary and impious could not be compelled to take up their residence for a while in the neighborhood of the two great cemeteries of Munich: they would not be long in crying out for the adoption of purifying flames and the innoxious columbarium.
