With the Compliments of DE. W. OLEITSMANN. WESTERN NORTH CAROLINA AS A Health Resort. BY W. GLEITSMANN, M. D., Physician in Charge of the Mountain Sanitarium for Pulmonary Diseases, ASHEVILLE, N. C. Read before the American Public Health Association, November, 1875, at Baltimore, and Reprinted from the Philadelphia Medical and Surgical Reporter, February, 1876. BALTIMORE: PRESS OF SHERWOOD & CO. 1876. WESTERN NORTH CAROLINA AS A HEALTH RESORT. The tendency of climatological science in our time is mainly directed to the study of the different constituents of climate, in order to ascertain thereby the fitness of special localities to certain classes of disease. The present sketch originated in the desire to make a small contribution to this department of our science, by furnishing a few data concerning a region heretofore unknown in its climatic relations to a great number of our people. Western North Carolina, with the adjacent parts of North- western South Carolina and Northeastern Georgia, contains the southern extremity of the Appalachian chain, which extends in a continuous range to the north, through the whole eastern part of the Union. The highest elevations of the whole chain are found in its southern part, and especially in western North Car- olina, thereby imparting special peculiarities of climate. The region which directly occupies our attention is bounded east and west by high mountain ranges, sloping gradually down, in the extreme north, to the southerly extension of the great Virginia valley, and declining very abruptly to the lowlands in the south. The boundary on the west is formed by the Unaka, Great Smoky, the Bald, Iron and Stone mountains, their high- est ridge coinciding with the State line between North Carolina and Tennessee. To the east we find the Blue Ridge proper, with the highest elevations east of the Rocky Mountains ; Black Dome being 6,707 feet above the level of the sea. The Blue Ridge in this section is the watershed between the Atlantic Ocean and the Mexican Gulf. All the streams having their sources east of the ridge empty into coast rivers, which flow, after short courses, into the Atlantic ; whilst to the west all the water flows into the Tennessee river, a tributary of the Ohio, and finds its outlet through the Mississippi into the Gulf of 2 Mexico, Six principal streams break through the high western mountain barrier, among them the Tennessee river itself; and this peculiar feature contributes greatly to the variety of the different valleys, and enhances the beauty of the landscape. Prof. A. Guyot, of Princeton College, New Jersey, who explored this country some time ago, published a series of measurements he had taken. In this list, fifty-one mountains, rising over 6,000 feet above the sea-level, are mentioned. Western North Carolina embraces an area of about five thou- sand square miles, and has its greatest extension from north to south. The length, from Virginia to Georgia, is about one hundred and eighty miles, while the breadth varies from twenty to fifty miles. The whole country is undulating, and perfectly level places, even of small extent, are rarely to be found. It can neither be called a valley nor a high plateau, as several high mountain-ranges, of which the Balsam Mountains are the most prominent, traverse it from northwest to southeast, and the spurs of which, extending all over the country, are the cause of its irregularity. The high barrier in the west, formed by the Great Smoky Mountains and their continuation, runs from southwest to northeast, and breaks the force of the northwest storms so frequently occurring, and so well known for their severity all over the eastern portion of our continent. The geological character is, in general, of primary formation, which gives to the water a purity and softness highly appreciated by strangers. Springs are numerous, and greatly add to the richness of vegetation, which clothes all the mountains to their very summits. The mountains are all covered with timber, and a great variety of species presents itsejf to the eye of the botan- ist.* The soil is rich, and especially on the summits of the hills, a fact which, although surprising at first sight, is easily explained by the circumstance that the decay of leaves and veg- etable matter is left undisturbed by the hand of man or the washing of rains. The clearness of the atmosphere, on bright, *Prof. W. C. Kerr, State Geologist, says, in his report just published, that of species found in the United States, east of the Rocky Mountains, there are— Oaks, 22, and 19 in North Carolina.

If we enter into special investigation of the individual cli- matic factors, we have the longest series of observations made by the volunteer observer in Asheville, for the Smithsonian Insti- tute, extending over a period of nearly eight years. This place is the principal town of Western North Carolina, being situated in the wide valley of the French Broad river, 2,250 feet above the ocean, and 250 feet above the river. It is located on an irregu- lar plateau, extending from the base of the last spurs of the Black Mountain, and is the true representative of a mountain climate. The place, owing to its southerly location (35° 36' north latitude), possesses the great advantage of being less subject to those great extremes of temperature under which the East- ern and Western States of the Union suffer so much. The importance of this subject may justify an explanation, by some details and figures, in proof of the correctness of my assertion. Asheville is famous for the coolness of its summers, the temper- ature of 90° being recorded only once in the whole period of eight years. The thermometer seldom rises above 85°, and the highest temperature in 1815 was 86° ; 1874, 88° ; and 8° the lowest point reached by the mercury in the Winter of 1874-75. The average summer temperature is 70.7°; and if we compare the extremes of heat and cold in cities having an equal or sim- ilar summer mean, the Chief Signal Office Beport for 1874 furnishes us the following interesting data, for the period from October 1st, 1873, to September 30th, 1874:— Ashevi Sandy Long B Clevela New Y Detroit Chicagt Denver Colorac St. Pau o “o M «H w QD p D 2 O noVS-’ C.
