and one may blister in a fiery blast registering 105 

 degrees in the shadows, as happened at Marquette 

 in the summers of 1917 and 1918/ although the icy 

 waters of Lake Superior are immediately at hand 

 but powerless to relieve. 



From January to March, and from June to De- 

 cember, the prevailing direction of the wind in the 

 Lower Peninsula is from the west and the south- 

 west; and while it prevails from the southwest in 

 April and May, there is a considerable amount of 

 east and northeast wind over the surface of the land. 

 Here the westerly winds are warm and moist; the 

 easterly winds are dry and indicative of unsettled 

 weather.^ In the LTpper Peninsula, the prevailing 

 northwest winds of the summer season, in the area 

 adjacent to Lake Superior, bring abundant rains 

 that, as C. F. Schneider observed years ago, keep 

 summer pastures green and luxuriant and warrant 

 belief in the future of this region as a dairy and 

 live-stock country. 



'July 29, 1917—2 P.M.— at Marquette the temperature 

 was 105 degrees F. and the wind blowing at the rate of 

 twenty-four miles an I'oiir from the Son* Invest. July 28-30, 

 1916, the temperature ranged from 100 to 101 degrees F. 

 (maximum) and the wind's maximum velocity was 16.24 

 and 28 miles an hour.
