A mountain residence is not desirable for thin, nervous people or such as are afflicted with any organic disease. A high altitude is too stimulating for this class of patients and tends to increase nervousness and aggravates organic disease. Such persons should seek a coast climate and a low altitude, which is sedative, rather than risk the high and dry interior. Any coast climate is better than the mountains for nervous people, but the Pacific Coast is preferable to any other because of its freedom from electrical storms and every other form of disagreeable meteorological disturbance that tries the nerves. The nervousness that is produced by a high altitude does not, as a rule, develop suddenly, but grows gradually upon the patient. Those of a sensitive nature feel it most and women more than men. After making a change from a low to a high altitude sleep may be sound for a time, but it soon becomes fitful and unrefreshing.
It has been discovered that altitude increases the amount of hemoglobulin and thus enriches the blood and is particularly beneficial to pale, thin people. It also sharpens the appetite and promotes digestion and assimilation.
Persons suffering from rheumatism, neuralgia, advanced pulmonary consumption, organic heart disease and all disorders of the brain and nerves should avoid a high altitude. Patients that are afflicted with any of the above-mentioned diseases are more comfortable in a low altitude and should choose between the coast of California and the low, dry lands of the lower Gila and Colorado rivers, according to the season of the year and the quality of climate desired.
The diseases which are especially benefited by the climate of Arizona are consumption, bronchitis, catarrh and hay fever. Anyone going in search of health who has improved by the change should remain where the improvement took place lest by returning home and being again subjected to the former climatic conditions which caused the disease the improvement be lost and the old disease re-established with increased severity.
Most sick people who are in need of a change live in a humid atmosphere where the winters are extremely cold and the summers uncomfortably hot, and to be benefited by a change must seek a climate in which the opposite conditions prevail. The climate of the southwest furnishes just what such invalids require. The sick who need cold or damp weather, if there be any such, can be accommodated almost anywhere, but those who want a warm, dry climate must go where it can be found. Not every invalid who goes in search of health finds a cure, as many who start on such a journey are already past help when they leave home. When a case is hopeless the patient should not undertake such a trip, but remain quietly at home and die in peace among friends.
As already intimated the climate of the Colorado basin is ideal in winter, but becomes very hot in summer. Its low altitude, rainless days, cloudless skies and balmy air form a combination that is unsurpassed and is enjoyed by all either sick or well. The heat of summer does not create sickness, but becomes monotonous and tiresome from its steady and long continuance. Many residents of the Territory who tire of the heat and can afford the trip take a vacation during the summer months and either go north to the Grand Canon and the mountains or to the Pacific Coast. Every summer witnesses a hegira of sun baked people fleeing from the hot desert to the mountains or ocean shore in search of coolness and comfort.
Life in the tropics, perhaps, inclines to indolence and languor, particularly if the atmosphere is humid, but in a dry climate like that of Arizona the heat, although sometimes great, is never oppressive or debilitating. It has its lazy people like any other country and for the same reason that there are always some who were born tired and never outgrow the tired feeling, but Arizona climate is more bracing than enervating.
The adobe house of the Mexican is a peculiar institution of the southwest. It may be interesting on account of its past history, but it is certainly not pretty. It is nothing more than a box of dried mud with its roof, walls and floor all made of dirt. It is never free from a disagreeable earthy smell which, if mingled with the added odors of stale smoke and filth, as is often the case, makes the air simply vile. The house can never be kept tidy because of the dirt which falls from the adobe, unless the walls and ceilings are plastered and whitewashed, which is sometimes done in the better class of houses. If the house is well built it is comfortable enough in pleasant weather, but as often as it rains the dirt roof springs a leak and splashes water and mud over everything. If by chance the house stands on low ground and is surrounded by water, as sometimes happens, after a heavy rain the walls become soaked and dissolved into mud when the house collapses. The adobe house may have been suited to the wants of a primitive people, but in the present age of improvement, it is scarcely worth saving except it be as a relic of a vanishing race.
In order to escape in a measure the discomforts of the midday heat the natives either seek the shade in the open air where the breeze blows, or, what is more common, close up tight the adobe house in the morning and remain indoors until the intense heat from the scorching sun penetrates the thick walls, which causes the inmates to move out. In the cool of the evening they visit and transact business and when the hour comes for retiring go to bed on cots made up out of doors where they sleep until morning, while the house is left open to cool off during the night. This process is repeated every day during the hot summer months and is endured without complaint.
The natives, also, take advantage of the dry air to operate a novel method of refrigeration. The cloth covered army canteen soaked in water and the handy water jug of the eastern harvest field wrapped in a wet blanket are familiar examples of an ineffectual attempt at refrigeration by evaporation. But natural refrigeration find its best illustration in the arid regions of the southwest by the use of an olla, which is a vessel made of porous pottery, a stout canvas bag or a closely woven Indian basket. A suitable vessel is selected, filled with water and suspended somewhere in midair in the shade. If it is hung in a current of air it is all the better, as any movement of the atmosphere facilitates evaporation. A slow seepage of water filters through the open pores of the vessel which immediately evaporates in the dry air and lowers the temperature. The water in the olla soon becomes cold and if properly protected will remain cool during the entire day.
