“The surface soil of Havana consists for the most part of a thin layer of red, yellow, or black earths. At varying depths beneath this, often not exceeding one or two feet, lie the solid rocks. These foundation rocks are (especially in the northern and more modern portion of the city, towards the coast of the sea and not of the harbour) quarternary and especially tertiary formation so permeable that liquids emptied into excavations are absorbed and disappear. In the southern and greater portion of the city, these rocks are of cretaceous formation, and so much less permeable that sinks and other excavations readily fill to overflowing. About twenty thousand persons or one-tenth of the population, live on land reclaimed from the sea, in large measure, by dumping on garbage and street refuse. Much of this reclaimed land was formerly mangrove swamps, and Havana still lies adjacent to these breeders of malarial poison. There are few if any towns in Cuba which are not subjected to malarial effluvia from mangrove or other swamps, and many of these suffer to greater extent than Havana.”

Messrs. Ariza and Herrera reported a population of 3000 on the reclaimed parts of the first district, 5000 on parts of the third and fourth, 5000 on part of the fifth, and 600 on part of the sixth district.

THE CLEANSING OF THE HARBOUR

“The sanitarian cannot hesitate to advocate, for general reasons if not especially for yellow fever, the cleansing of the harbour, the cessation of daily additions to it of large masses of filth, and the replenishment of it by constant currents of pure water. To accomplish the last, it has been much insisted on, in the United States, as well as in Cuba, that canals should be dug. Out of Cuba it ought to be better understood that Havana is by no means deficient in highly educated, skilful, practical engineers, who are fully alive to the sanitary interests of the city, and to the merits of this especial subject. Among these, Colonel Albear stands pre-eminent, and in September, 1879, he delivered before the Academy of Sciences an extremely able address on this subject, which is so full of instruction, on other local conditions also of interest to the sanitarian, that this address has been translated and is presented, as a most interesting part of this report. Colonel Albear seems to have conclusively demonstrated the impracticability of these proposed canals; and my own conviction is that if practicable they could not possibly place the small harbour of Havana in as favourable sanitary conditions as are by nature the large harbour of Matanzas and of Cienfuegos, where yellow fever none the less prevails.”

DRAINAGE

“In Cuban cities, generally, good drainage is not found except in such comparatively inextensive parts where nature required little or no assistance. Even in Havana, the oldest and wealthiest city, the visitor is often astounded, especially in the rainy season, by impassable mud-holes, and green, slimy, stagnant pools in the streets and in the backyards. This condition was found even in the Pueblo Nuevo ward, which is located so admirably for good drainage that little labour would be required to make it perfect.

“Messrs. Ariza and Herrera reported: ‘Havana has no sewers save in a few principal streets. These sewers have been built at interrupted intervals, without reference to any general plan for drainage. They are seldom cleaned and are generally obstructed in part or wholly with sediment or filth from the streets, and exhale offensive odours. As the sewers are few in number, the greater part of the water of the city empties through the streets, into the harbour or the sea; but the quantity flowing into the sea is comparatively small.’ Mr. A. H. Taylor, a civil engineer, thoroughly informed on this subject, testified that the sewers of only three streets subserved any good purpose whatever, and that the remainder were so defective that the city would really be much better off without them. Through the gratings, which have large interspaces, the dirt and refuse of the streets find such ready entrance that a number of these sewers were soon filled up, with apparently solid materials, to within a few inches of the surface openings. Since very few houses or privies are connected with sewers, these are less offensive than they would otherwise be, but no one who has seen them can find any words except of unhesitating condemnation for their grossly defective structure.”

THE PAVING OF STREETS

“Less than one-third of the population live on paved streets, and these are well paved and kept as clean, it is believed cleaner, than is usual in the United States. The remainder live on unpaved streets, which for the most part are very filthy. Many of these, even in old and densely populated parts of the city, are no better than rough country roads, full of rocks, crevices, mud-holes, and other irregularities, so that vehicles traverse them with difficulty at all times, and in the rainy season they are sometimes impassable for two months. Rough, muddy, or both, these streets serve admirably as permanent receptacles for much decomposing animal and vegetable matter. Finally, not less, probably more, than one-half of the population of Havana live on streets which are constantly in an extremely insanitary condition, but these streets, though so numerous, are not in the beaten track of the pleasure tourist, in which capacity the writer, in 1856, spent ten days in Havana without witnessing many of the evils now testified to with emphasis.”
