Fevre River, at Galena, runs through a narrow vale, and is hedged in on either side by ranges of hills. The town is built at the base and on the side of the western ridge, which is here quite precipitous. The valley itself is overflown with every rise of the Mississippi above this point. The waters of the Fevre River between Galena and its junction with the "Father of rivers" are very sluggish--so that the waters of the Mississippi flow up to Galena often three or four times a year, and flood the whole lower part of the town. Since I have been here the third rise which they have had this season occurred, occasioned as it was supposed by the melting of the snows and ice around the sources of the most northern tributaries of the Mississippi. One thing is very remarkable in relation to the whole class of western tributaries to this stream. The freshets to which they are subject, all occur at different seasons, beginning with the southernmost and ending with the most northerly. This is accounted for by the fact, that, as these streams take their rise at different points of latitude in the Rocky Mountains, spring and summer reach the source of each of them in regular progression from south to north, by a few weeks later. This is a most merciful provision: for if the freshets in two or three of these streams were to happen at the same time, the effects would be desolating. Let the Red River, the Arkansas, and the Missouri, pour their swollen streams at the time of their annual freshets, together into the Mississippi, and the whole lower regions for hundreds of miles above and around New Orleans would be one unbroken sea. What a tremendous armament of destruction has the Almighty here! Have not the inhabitants of that city which has seated herself as a queen at the mouth of this river, reason to remember that the Lord can bury them in a moment in the midst of the sea? He has only to blow with his wind, and the waters will flow, and the depths cover them! Let those who openly and remorselessly trample on every law of God consider this and tremble.
