The guilt of Spain in permitting this shocking condition to continue, cannot in any way be palliated. For four hundred years she has had sway in the island, free to work her own will, and drawing millions of dollars of surplus revenue out of the grinding taxes she has imposed. The installation of a sanitary system of sewage, which should discharge into the open sea instead of into this cesspool which lies at the city's feet, would have been the first solution of the difficulty. The threat of danger would have been finally averted by the expenditure of a few hundred thousand dollars, which would open a channel from the further extremity of the harbor to the ocean eastward. The distance is but a few miles and the engineering problem a simple one. This and the construction of a jetty northwestward from the point on which Morro Castle stands, would divert a portion of the current of the noble gulf stream into the harbor entrance, and the foul pond of to-day would be scoured of its filth by a perennial flood which could never fail. Vera Cruz, on the Mexican coast, has proven that it is possible to exterminate yellow fever, and it is a duty owed to civilization that Havana shall follow along the same path. If all other excuses were to be ignored, the United States for years has had ample cause for intervention in Cuban affairs, as a measure of safety to the health of her own citizens, as truly as one man may complain to the authorities if his neighbor maintains a nuisance in the adjoining yard. THE BUSINESS QUARTERS OF HAVANA. Once anchored in the safest place in the harbor, the mail steamers are surrounded without delay by a fleet of peculiar boats of a sort seen only in the bay of Havana. For a bit of silver, the traveler is taken ashore, the journey to the landing stage being a matter of but a few moments. The journey through the custom house is not a formidable one, for unless there is suspicion of some contraband goods, the customs officers are not exacting upon travelers. At the door of the custom house, or aduana, wait the cabs, which are cheaper in Havana than in any other city of the new world, and they serve as a conveyance to the hotels, which are all grouped in the same neighborhood.
