* Dr. Shumard, geologist and naturalist upon the exploring expedition of Capt. Marcy, furnished us with the accom¬ 
panying series of thermometrical observations made at Fort Smith. They are of particular interest in the determination 
of the character of the climate at this place. For the year ending June 1, 1852, the mean temperature was 65°. 47. The 
mean for August, the warmest month, was 890. 4. The lowest, 34°. 84, was the mean for January. But one storm of 
snow was recorded during the year ; that was two inches, in January. Rain occurred every month ; the least in Septem¬ 
ber, October, and January, averaging one and one-third inches. May appears to be the rainy season—twelve and one-six¬ 
teenth inches having been measured during the month. For the year the fall recorded was fifty-one and one-fourth inches. 
There were two hundred and nineteen moist days, eighty-two of which were rainy, and one hundred and twenty-six dry 
days ; twenty not having been noted. The mean temperature of the summer was 86°. 98 ; of autumn, 69°. 11; of winter, 
42°. 28 ; of spring, 63°, 57. The highest temperature recorded was 104°, in August; the lowest, 4°, in January. The 
summer referred to is that during which the place was visited by the cholera.
