found. There are no roads, and for many miles not even a solitary settler is to be seen, but with a good horse and a guide familiar with the cracks, blows and 'sand slews' the region can be penetrated and the earthquake features examined. It is in the depths of these forests along the St. Francis river that the cracks reach their greatest development. How wide they may have been when first formed and
Fissures of another, but equally conspicuous type are the land-slide cracks formed where steep slopes, such as those along the east side of Reelfoot Lake in western Tennessee, occurred within the earthquake area. Here the bluffs, which are several hundred feet in height, were literally shaken to pieces by the shocks, the trees uprooted, overturned, or prostrated, and great masses of earth precipitated down the steep hillsides. Figure 2 shows some of the scarps thus formed, while another shows trees overturned at the same time (Fig. 3). Sometimes the original trunks are decayed and gone, all perhaps but a projecting stump, but shoots from the original have often taken their place as giants of the forest.
The features for which the New Madrid earthquake is most renowned, however, are the swamps and lakes which resulted from the warping of the surface. The former may be seen at many places in southern Missouri and northern Arkansas. In the view of such a
