PICTURES. 

 The pictures we have been able to give are as follows : 



THE GATEWAY IN THE u GARDEN OF THE GODS." The 

 two large remnants of a perpendicular stratum of red sand- 

 stone which was cut in two by erosion form this gateway. 

 In the foreground is seen a stratum of white sandstone, also 

 on its edge. In the distance Pike's Peak is dimly outlined. 



A SINGLE BUTTE. This has already been described, and 

 will be readily recognized. 



GLEN EYRIE. We give two views ; one of the " needle 

 rocks," as a remarkable example of the work of erosion, and 

 the other of the edge of one of these upturned ledges which 

 gives a fine idea of its structure. 



MT. PRINCETON. This mountain is in the Sawatch Range. 

 It is noted for its symmetry. The broad valley of the Arkan- 

 sas is in the foreground. 



THE WESTERN TWIN LAKE. This is the smaller of the 

 two lakes. Two unnamed peaks of the Sawatch chain are 

 shown in the background. 



WESTERN SLOPE OF THE CONTINENTAL DIVIDE. This 

 view is in the Twin Lake region. 



, BLUE RIVER AND MOUNTAINS. This view is given as 

 a specimen of a deep and wooded valley. The slope of the 

 mountains, it will be noticed, is very steep. The height of 

 the ridge above the valley is 3000 feet. 



MT. LINCOLN. The view is taken from Hoosier Pass, 

 and embraces Montgomery Gulch on the right hand side of 

 the picture. The trachytic dikes spoken of in the report are 

 well brought out on the side of the mountain. 



MT. GRAY. The view is taken from the Argentine Pass, 

 and shows Mt. Torrey on the right.
