NO. I AIR AND TUBERCULOSIS HINSDALE 6l 



In the location of the state sanatorium for tuberculous patients 

 in Minnesota, an interior and northerly location was wisely chosen, 

 150 miles south of Lake Superior, at Lake Pokegama, near the head- 

 waters of the Mississippi. 



The Wisconsin State Sanatorium has been located on Lake Neba- 

 gamon, thirty miles from Lake Superior. 



Such small lakes as Lake Pokegama in Minnesota ; the Muskoka 

 Lakes in Ontario, where the Canadian National Sanitarium Associa- 

 tion has established two sanatoria for consumptives ; and the Saranac 

 Lakes in the Adirondack Mountains, have no such power to modify 

 the qualities of the atmosphere. Whatever influences are attributa- 

 ble to these smaller bodies of water are small, compared with that 

 of the forest and mountains. Undoubtedly a small lake is a desir- 

 able feature in connection with a sanatorium, as it provides sources 

 of amusement throughout the year and adds greatly to the beauty of 

 the landscape. The writer spent six summers at Lake Placid in the 

 Adirondack Mountains at an elevation of 1,860 feet. This is some- 

 what more protected than the Saranac Lakes, St. Regis Lake or 

 Long Lake, and, in his opinion, is quite as well suited as a residence 

 for tuberculous patients as any other locality in the Adirondacks. 

 The State of New York has built its large State Sanatorium at 

 Ray Brook only four miles distant from Lake Placid. The State of 

 Rhode Island has chosen Wallum Lake for its new Sanatorium, 

 views of which are here given.^ 



CHAPTER IV. INFLUENCE OF COMPRESSED AND RAREFIED 

 AIR; HIGH AND LOW ATMOSPHERIC PRES- 

 SURE; ALTITUDE 



No phase of the tuberculosis question has been so vigorously 

 debated as the influence of altitude ; no feature of the subject is so 

 far from satisfactory solution. The battles between the Highlanders 

 and the Lowlanders of Scotland seem to have been revived in the 

 attempts to settle this question. Instead of the claymore and battle- 

 axe, we have an array of statistics in serried columns marshalled by 

 the leaders of the opposing forces. This history of the conflict 

 would make as large a record as the Medical and Surgical History 

 of the War of the Rebellion. And the end is not yet in sight.

 ble climate " obtained at home by housing the patient behind double
