The city was divided into twenty inspection districts, each district under the charge of a sanitary inspector. This inspector was required to get around to each house in his district once a month and make a careful inspection with regard to mosquito-breeding, and report to the central office on a printed blank the conditions found. If this report indicated that the condition of the premises amounted to a sanitary nuisance, the householder was proceeded against. An order had been promulgated making it a sanitary nuisance for any householder to have mosquito larvæ on his premises. The health officer was given authority to impose a fine for such nuisance; the fine was collected by the Cuban courts, and the proceeds of the fine deposited in the Cuban treasury. The health officer had authority to remit the fine at any stage of the proceedings. In practice, it came about that the whole matter was settled in the Sanitary Department. We employed a lawyer to whom cases of fines were referred. When a householder was reported by the sanitary inspector as having larvæ on his premises, he was notified that under the sanitary ordinance he was fined five dollars for having this nuisance on his premises, but that if the nuisance were abated, the fine would be remitted. This usually brought the man promptly to the office with the statement that the nuisance had been abated. An inspector was sent around, and if the householder’s statement was found to be correct, the fine was remitted. In a certain number of cases this notice caused no action on the part of the householder. In these cases the fine was sent to the judge of the district for collection by him. In the few cases in which the first notice had not brought the householder to terms, this action by the court did. If he reported that he had abated the nuisance and the inspector when sent to investigate found this to be the case, the fine was withdrawn. In this way we did very little fining. Out of about twenty-five hundred fines levied in the last nine months of 1901, only fifty were finally imposed and deposited in the treasury.
