device is simple enough. The main feature is a small house, say five feet by seven, and six feet high, which is practically a refrigerator, with double roof and walls for packing the ice. A window is put in for light, and the patient is laid in his bed in a temperature of about freezing. He has no attendants inside, except when needed, and he is watched through the window. This method usually kills or cures the patient in from twelve to thirty-six hours. At first the box was not successful, for condensation practically drowned the patient out; but that was remedied by draining the water off. There is a great difference of opinion in relation to the efficacy of this treatment; some physicians entirely disapproving it, while others as strongly recommend it. What may be done for the proper sanitary regulation of Santiago is a serious problem, as, owing to the distance from the sea and the landlocked character of the bay, the sewage, which may be easily drained down the sloping streets of the town, is bound to remain near the shore. For the present, Major Barbour, Superintendent of the Santiago Street Department, disposes of the sewage by sprinkling it with petroleum and burning it. Manzanillo, population nine thousand, with a large and beautiful military plaza, has filthy streets and no public improvements of any kind looking to the health or comfort of the people; and the people seem to like it. The streets are unpaved, and Manzanillo mud is an alliterative term which has become a household word for the nastiest mud on the Island. The town is twenty feet above the bay, with hills to the rear, and near it are great swamps filled with mosquitoes and malaria, which spread themselves abroad in every direction. Guantanamo, population nine thousand, seven miles inland, one hundred and fifteen feet above the bay of the same name, is situated on the river Guaso, and might be easily and thoroughly drained; but no efforts have been made in that direction, and malaria and fevers prevail. With any kind of decent care, the city could be made as healthful as any in the same latitude. Pinar del Rio, the capital of its province, with 5500 population, is situated 25 miles from the sea, 160 feet above it, and on a hill 70 feet high. It is in the midst of the famous Vuelta Abajo tobacco district, and it might be made a clean town; but its streets are narrow and filthy, its people are a mixture of French and African, and it is a reflection on the great American Republic, in that it was founded in 1776. Batabano, the southern seaport of Havana, thirty miles away, in its narrow, dirty streets presents a condition of neglect and nastiness suggesting that it is also a receptacle for the surplus refuse of the capital.
