APPENDIX. 189 



C. 



Extract from a letter from J. M. Batclielder, Esq., Saco, Maine, accompanying 

 his observations : — 



" This place is situated on the Saco River, three miles from the ocean, from 

 whence we have the south wind, which, you will observe, is the prevailing one 

 during the summer months. There are frequently local currents down the valley 

 of the river ; but I think that the observations are, in the main, correct." 



D. 



For a description of the meteorological stations in the State of New York, see 

 the reports of the Regents of the University of that State, as made annually to 

 the legislature. 



E. 



Lafayette College, where the observations for Easton, Pennsylvania, were taken, 

 is situated on an abrupt bank of the Delaware River, nearly 200 feet above its 

 surface, and distant from it not more than one-fourth of a mile. There is no local 

 cause that can materially affect the direction of the wiud, unless it be the Blue 

 Mountains, which are about twenty miles off. 



Extract from a letter from George Mowry, Esq., Somerset, Pennsylvania, accom- 

 panying his observations : — 



" The locality of Somerset is about half way between the Alleghany and Laurel 

 Hill, which mountains run nearly north-east and south-west. There is no other 

 table-land between us and Laurel Hill ; but a few miles south and east of us, Negro 

 Ridge lies, flattened down to within fifty or sixty feet of the level of Somerset ; — 

 farther south-west, toward the Maryland line, it is a considerable mountain. You 

 are right in your inference that we are at the head of a branch of Youghiogeny; 

 and, on a close inspection of a good map, you will observe that the waters flow 

 north and south from us — consequently we are situated on some of the highest 

 table-land in the State." 



G. 



Extract from a letter from Professor McCay, Athens, Georgia, accompanying an 

 abstract of his observations : — 



" I do not think there is any local cause for our winds. There are no mountains 

 within sixty or seventy miles — no regular ridges for a still greater distance. The 

 country is undulating, with no changes of elevation amounting to five hundred feet, 

 in a circle around of fifty miles. The river near us is very small. Its course very 

 irregular, sweeping round us in a semicircular course. Other streams near us have 

 a general course to the south-east — nearly south."
