The lowest temperature which Mr. Ball once observed there in the winter of 1833 was 6-1/2° of Reaumur below the freezing point, or 17.4° Fahrenheit (Message from the President of the United States to Congress, 1844, p. 160; and Forry, Clim. of the U. States, p. 49, 67, and 73). A cursory glance at the summer and winter temperatures above given, shews that on and near the west coast, a true insular climate prevails. The winter cold is less than in the western parts of the old continent, and the summers are much cooler. The most striking contrast is presented by comparing the mouth of the Oregon with Forts Snelling and Howard, and the Council Bluffs, in the interior of the Mississipi and Missouri basin (Lat. 44°-46°),--where, to speak in the language of Buffon, we find an _excessive_, or true _continental_ climate,--a winter cold, on single days, of -28°.4 and -30°.6 Reaumur (-32° and -37° Fahr.), followed by mean summer temperatures of 16°.8 and 17°.5 Reaumur (69° and 71°.4 Fahr.)
