Some portions of the following pages have already appeared in the monthly numbers of the Sanitary Engineer, and the complete work is now published with a view to assist Surveyors of Towns and others who are directly engaged in providing that house dustbins shall be regularly cleared, and streets kept clean; and also in the hope that it may be the means of drawing some public attention to the question, thus showing the householder something of what is being done for his welfare by Sanitary Authorities, and how each individual may assist in the good work, instead of, as is now frequently the case, inadvertently or purposely retarding the execution of some very necessary though unostentatious sanitary measures. I am not aware that any book, or even pamphlet, has yet been written on this subject, and I venture to believe that in these pages there may be found something to interest all readers.
