The scavenger system is also very defective. Citizens are required to pay for the removal of their ashes, trash, and garbage. Garbage collections are not made by the municipality, but by private contractors, and any sort of receptacle, covered or uncovered, can or box, is pressed into service by householders. It is by no means uncommon to find streets and alleys littered with ashes, garbage, bottles, tin cans, beer cases, and small kegs. Dirty streets are by no means exceptional in Johnstown, even though the State of Pennsylvania has a law (act of Apr. 20, 1905) which provides for the punishment of any person who litters paved streets. It reads, in part, as follows (sec. 7 of Pamphlet Laws, 227): “From and after the passage of this act, it shall be unlawful, and is hereby forbidden, for any person or persons to throw waste paper, sweepings, ashes, household waste, nails, or rubbish of any kind into any street in any city, borough, or township in this Commonwealth, or to interfere with, scatter, or disturb the contents of any receptacle or receptacles containing ashes, garbage, household waste, or rubbish which shall be placed upon any of said paved streets or sidewalks for the collection of the contents thereof. “Any person or persons who shall violate any of the provisions of this act shall, upon conviction thereof before any magistrate, be sentenced to pay the cost of prosecution and to forfeit and pay a fine not exceeding $10 for each offense, and in default of the payment thereof shall be committed and imprisoned in the county jail of the proper county for a period not exceeding ten days.” In a report on infant mortality to the registrar general of Ontario, 1910, Dr. Helen MacMurchy says: “Improve the water supply, the sewerage system, and the system of disposing of refuse; introduce better pavements, such as asphalt, and at once there is a decline in infantile mortality.” All these are sanitary features in need of great improvement in Johnstown, and unquestionably a lowered infant mortality rate would reward any efforts for their betterment. HOUSING In Johnstown the so-called “double” house predominates, usually frame. The double house is in reality two semidetached houses built upon a single lot. Rows of three or more houses of two, three, or four rooms each are common, and they are known locally as three-family, or six-family houses, as the case may be. Sometimes these are “rear houses,” that is, they are built behind other houses that face the street, on the same lots and in fact are approached by way of a narrow alley running alongside the house that has its frontage directly on the street. For this type of house water-closets or privies are often in rows in the yard or court that is used in common by all families. (See Plates Q and R.) In some places they are too few in number to permit each family to have the exclusive use of one.
