The range of water in these years is from 24.356 to 42.591 inches. In 

 1847 the water was 38.99, and in 1838 was 25.46. The water has not ex- 

 ceeded 39 inches but once in 28 years, and has been below 30 inches seven 

 of the 28 years. The range is chiefly between 30 and 35 inches. Are we 

 able to trace, to any definite results in vegetation, even the extreme annual 

 difterences of the water fallen ? 



III. INTERESTINa FACTS AND SPECIAL PHENOMENA. 



The Year 1864 commenced with very severe weather in the Mississippi 

 valley ; the storm having begun on the last day of 1863, with a heavy rain, 

 and snow, wind and cold towards evening. The Newyear was the coldest 

 ever known at St. Louis; 19° to 24° below zero, and out of the city 25° 

 below. The snowstorm was great all over the west : At Memphis, the cold 

 was 10" below zero ; at Cairo, 16° below ; at Louisville, 9J° below, though 

 rain was falling there at noon the day before at 47° ; at Chicago, Newyear 

 22° below, in the suburbs 28° to 30° below, and below zero for seven days ; 

 at Bloomington, Illinois, Lat. 40J, 20° to 30° below zero, and for the first 

 nine days the average at sunrise was 15° below ; at Milwaukee, 30 to 40° 

 below; at Madison, Wisconsin, 34° below, and 39° below on January 2, so 

 that the mercury congealed at the Hervey Hospital; at St. Paul, much be- 

 low zero, 38° below on the 2d, 30° below on the 3d, and for three days not 

 warmer than 10° below, while at Fort Snelling, and more exposed places in 

 that vicinity, the cold of the 2d was —50° by the spirit thermometer ; 

 at Minneapolis, Minnesota, Lat. 45, 30° below and not above 20° below all 

 day, 28° below on the 2d, and for three days not higher than 10° below ; at 

 Cincinnati, 8 to 10° below zero, while the day before (December 31) there 

 was rain all over that section, when at 8 p.m. the western blast brought the 

 snow and lowered the temperature 54° in three hours ; at Indianapolis, 20° 

 below, and two days of snowstorm ; at Buffalo, the storm began at 4 a.m. 

 with rain, and at 9 p.m. the cold was 9° below zero, the violent wind driving 

 the waters of Lake Erie over the lower part of the city, and destroying the 

 railroad, a greater flood than for 16 years ; at Rochester, the storm began 

 early, thermometer 32° at 7 a.m., fell to 1° below zero at 9 p.m., and was 

 4° below next morning (the 2d) ; at Toronto, very cold on the 2d ; at Os-
