TABLE OF LENGTHS, ETC. 



107 



Table sliowlng the lengths, sums of ascents and descents, equated lengths, cost, &c. , of the several 

 routes explored for a railroad from the Mississippi to the Pacific. (For the grades, see the 

 profiles accompanying the report.) 



a These are the estimates of the office, those of Gov. Stevens having been brought to the same standard of increased cost as the other routes, 

 and his equipment reduced to that of the other routes. His estimates were $117, 121,000 and .*! 10,091,000. 



b Those s-ums do not include the areas of cultivable soil as far west, as the Cascade and Sierra Nevada mountains. 



c Supposing the route to be a straight line, with uniform descent from the Un-kuk-oo-ap mountains (near Sevicr river) to the entrance of the Tah-ee- 

 chay-pah Pass the most favorable supposition. 



d This estimate for the route near the 35th parallel is thought to be largely in excess. 



The sum of Ihe minor undulations (not included in the sum of ascents and descents here given) will probably be greater for the route of the 47th 

 parallel than for the other routes ; that for the route near the 32d parallel will probably be the least of all. 



With the amount of work estimated for the roads in this report, the equated lengths corresponding to the sum of ascents and descents has but little 

 practical value. With a full equipment and heavy freight business, the sum of ascents and descents becomes important.
