CLIMATE SANITARY RELATIONS. 475 



few miles from the northern line of Pennsylvania. Of this 

 region as an alpine summer residence for invalids, Dr. Drake 

 remarks : 



"When describing the sources of the Alleghany River, including 

 Chautauque Lake, we were brought, by a southern route, upon the 

 water-shed which we have now ascended from the north. It may be 

 regarded as the great salient terrace, or projecting table-land of the 

 Appalachian Mountains; that portion which advances farthest to the 

 northwest, from the central axis of the chain, that which ap- 

 proaches nearest to the great lakes. Its tabular yet undulating or 

 hilly surface results from its resting on a broad outcrop of Devonian 

 shale or sandstone, in which the former greatly predominates." 



Then follows a description of the region ; after which, he 

 thus proceeds : 



"Here, then, are all the requisites for a comfortable and curative 

 summer residence. I will mention a few classes of patients to whom 

 it would be likely to prove beneficial. 



"First. Those who are inclined to* tubercular consumption, or in 

 whom the disease, although fatally established, is not so far advanced 

 as to confine them to the house. To which may be added, children 

 affected with scrofula in the external lymphatic ganglia, the skin, 

 and the eyes. 



"Second. Those who have had their livers and spleens deranged 

 in structure or function, or their constitutions otherwise shattered, 

 by repeated attacks of autumnal fever, in low and hot situations. 



"Third. Dyspeptics, from any and all causes; hypochondriacs, 

 and those subject to chronic hysteria, or any other form of morbid 

 sensibility." 



Then follows a flash on the fallibility of drugs, and the 

 immense power of "simple diet," "new scenery," "active 

 exercise," and the " disuse of medicine," with kindly guide- 

 book information as to comfortable localities. To this suc- 

 ceeds some indications of the summer climate of the re- 

 gion : fires at night acceptable in July and August ; Indian 

 corn frost bitten in August ; peaches ill at ease ; " wheat 

 and hay harvest in August." He then adds : 



"It may be said that the Virginia springs are more elevated, and, 

 therefore, better fitted for summer sojourn. But their greater eleva- 

 tion of five hundred feet, would, in the reduction of temperature,
