tar was not so valuable in this work as the rosin. Large quantities of quicklime were used at Johnstown, and found to be very valuable for drying the cellars and, absorbing unpleasant odors. The people were advised to whitewash their cellars and homes a number of times, as the lime was believed to be very beneficial. Chloride of lime was used also in sprinkling in the cellars and about the houses. The Board of Health also furnished in solution bromine, chloride of lime, carbolic acid, and Quibbells's disinfectant. These were applied by means of sprinkling-cans. So soon also as the streets were cleared of the débris, two sprinkling-carts were set running. These used a solution of disinfectants, which had a good effect upon the general atmosphere, and an excellent moral effect, maintaining the confidence of the people. At times, the workmen who are cleaning up the district will imagine that they detect foul odors, and that it is dangerous for them to work without a liberal use of disinfectants. In these cases the presence of a laborer with a sprinkling-can, applying a solution of disinfectants, produces a very reassuring effect. Disinfectants should be freely used about the morgues and in every place where it can be hoped that they will do good. In this connection it may be stated, to the credit of the manufacturers of disinfectants, that, without knowing the means of the Board of Health to pay them, they promptly filled all orders for their supplies without a moment's questioning.
12. That the district may be entirely within the control of the sanitarian, it is important that, as soon as possible, a house-to-house inspection or survey be made of all the houses which are occupied in the district. This survey should be carefully recorded on blanks prepared for the purpose, and should state whether the house is occupied by owner or tenant, the number of rooms, number of families, the adult males, the adult, females, and children under five years of age. It should also state the condition of the cellar, kitchen, and living-rooms. The water-supply should be examined and reported upon, as to source, condition, and amount. The drainage of the premises should be carefully looked into. The privy or water-closet should receive a minute inspection. The surveyor should examine the condition of the yard and stable, and the streets and alleys about the house. Note should also be made of any present sickness in the house, and of the existence of any contagious disease in the house during or within six months preceding. If any deaths have occurred within the house in a year, record should be made of them. With all these points before the Board of Health, if the survey has been made with care, it will not be difficult for the Board to maintain good health in the devastated district—certainly not if they have the confidence of the survivors. If the devastated district
