 as the crossing of the North Platte, and on the south includes 

 the Pikes Peak group.

 United States from Alabama to northern Maine. 



Blue Ridge — includes the ridge extending from a few miles 

 north of Harper's Ferry to northern Georgia. 



Appalachian Plateau — includes the entire plateau forming the 

 western member of the Appalachian System, known in the north 

 as the Allegheny Plateau and in the south as the Cumberland

The following extracts from the Report of Department of 

 Highways, published in December, 1906, relative to the King's 

 River Canon Road, will be of interest to the members ; the first 

 extract is from the letter of the State Highway Commissioner 

 and the Deputy County Surveyor of Fresno, describing the pre- 

 liminary investigation, and the second is the report of work 

 already undertaken : — 



" It will be found that the beginning should be at the end of 

 a wagon-road built through the General Grant National Park 

 to the northeast gate, a short distance from the summit of the 

 divide which must be crossed, then ascending this ridge and 

 crossing it, whence the Hne should descend the drainage basin 

 of the Ten-Mile Creek to a point near the end of a road now 

 terminating on Ten-Mile Creek. This distance must be cov- 

 ered in a manner that will permit of a good grade, and therefore 

 its particular line would be left to the work of survey. From 

 this point it would run down the right bank of Ten-Mile Creek 

 on the most advantageous ground, gradually descending to the 

 South Fork of the King's River just below the lower one of 

 the three limestone points named Windy CHff by the Geological 

 Survey; thence up the South Fork to a point nearly opposite 

 Grizzly Creek, where the river is to be crossed and the line 

 continued on comparatively flat ground as far as may be required. 



" By this route, the road will contain no adverse grades from 

 the first ridge east of the park to the river. The drop in eleva- 

 tion from this ridge to the previously mentioned point on Ten- 

 Mile Creek is 2,200 feet, requiring 6.6 miles of road at six per 

 cent to make the descent. From the Ten-Mile Point to the 

 South Fork of the King's River the difference in elevation is
