Frequency of Collection
The number of collections that should be made in a given period depends upon the amount of ashes, the density of population, the season of the year, the climate and the degree of cleanliness desired. Most cities collect more frequently in winter than in summer and some collect more often in the business districts than they do in residential and outlying districts.
Samuel A. Greeley, sanitary engineer, believes that ashes and rubbish should be collected at least twice monthly even in summer. Most cities do better than that, some collecting daily and many collecting more than once a week.
