At Malone the temperature (reduced to sea-level) for 

 The year is 5.2° below the average of Lat. 45° 00'. 

 January is 14.2° below the average of Lat. 45° 00'. 

 July is 1.3° below the average of Lat. 45° 00'. 



These departures, although considerable, are not greater than 

 might be expected between restricted local conditions and an 

 average which includes the widely different thermal states of 

 oceans and continents. A better idea of the irelaition which tem- 

 perature bears to geographical position is obtained by tracing 

 over the Northern Hemisphere the thermal belt in which this 

 State is included. It is to be noted that for this purpose conti- 

 nental temperatures have in all cases been reduced to sea-level.* 



The isothermal line of 70 degrees, which will be observed on 

 the chart for July to pass from the Grreat Lakes over northern 

 New Yoirk, extends thence eastward through New England to the 

 vicinity of the coast, where it again turns toward the southwest, 

 meeting the line of 70 degrees which appears over eastern Long 

 Island. This isothermal then passes directly eastward over the 

 Atlantic near paT-allel 40 degrees, intersecting the coast of Europe 

 in northern Spain. Reaching the warmer land surface, it tends 

 siomewhat north of east through central France, Austria, cen- 

 tral Russia and Siberia. Near the eastern coast of the latter 

 country it turnis southward through 20 degrees of latitude and 

 passing to the Pacific over the island of Japan, continues nearly 

 eastward, meeting the coast of America in central California. 

 Thenoe it follows the meridian of 120 degrees west well north- 

 ward into British America before again turning to the southeast 

 in the direction of the Great Lakes and northern New York. 



The line indicating 74 degrees in July passes from New York 

 directly southward over the ocean until opposite Virginia; thence 

 slightly south of east to Moiroooo in north Africa, where it turns 

 northward to France; thenee passes throngh southern Europe 

 (north of the Italian penimsula) to the Black sea through central 

 Asia at latitude 50 degrees, and near the coast turns southward 

 to Japan. Diverging somewhat from the isotherm of 70 degrees,
