DOME ROCKS IN CUSTER PARK, SOUTH DAKOTA.—In this photograph we have another striking example of the curious and wonderful natural formations of this locality, one of the most remarkable scenic regions in all the world. These rocks seem to have been built by human hands and fashioned with a purpose into all sorts and shapes of grotesque and gruesome figures, and yet it would be impossible for human hands to mold such wonders. Nature, in one of her spasms, brought them forth, and imprinted upon their face the agony of her travail. ] ------------------------------------------------------------------------ [Illustration: SQUAW’S CHAMBER, DELLS of the WISCONSIN.] Signal Rock is only a short distance from Crow Butte, and is a similar formation, though not nearly so large; and while the summit is nearly as high, it is peaked and not difficult to reach. It derives its name from the use to which it was frequently put by the Indians in previous years, who by means of fire at night were able to signal to their friends as far away as the Bad Lands of South Dakota. The Fremont, Elkhorn and Missouri River Road crosses the Burlington at Crawford, and our work of photographing the Black Hills district being completed, the trip back to St. Paul was made, and a junction with other members of the expedition was formed, whose artist labors have already been described.

The head of navigation on the Mississippi is unalterably fixed at St. Paul, for above that point the river is a brawling stream, flowing over ledges and rushing through contracted passages lined with bluffs. At Minneapolis are the Falls of St. Anthony, but no longer do these present the furious aspect which once characterized them, for the wild riot of turbulent waters that formerly went dashing over a high brink with a roar that made the shore to tremble, have been harnessed, and are now driven over sloping tables so as to glide softly into the bed below. The channel, too, has been cut and buttressed with masonry, so that the strong right arm of the falls is made a servant of commerce in supplying the motive-power for many immense flouring mills. ------------------------------------------------------------------------ [Illustration:
