"I'll be glad to explain that," he eagerly replied, "for I am quite proud of it, I assure you. There are many buildings throughout our larger cities that were erected as cheaply as possible and without a single thought for the safety of their tenants. So many disasters have resulted from this that of late years building inspectors have been appointed in every locality to insist on proper materials and mechanical efficiency in the erection of all classes of buildings. These inspectors, however, cannot tear the old buildings down to see if they are safe, and paint and plaster cover a multitude of sins of unscrupulous builders. Usually the landlord or owner knows well the condition of his property and in many cases refuses to put it into such shape as to insure the safety of his tenants.
