The party engaged to survey the above Road started upon their duties on the 14th day of last August and arrived here on the 14th inst., having consumed exactly three months in performing the duties pertaining to their survey. Of the sixteen who started out, but four continued until the survey was completed. Considerable sickness was experienced by the corps of engineers, and the assistant engineer died en route.
But as intimated above, the survey is now concluded, and yesterday some $4,000 was paid the surveying party.
The Road as surveyed will start from East St. Louis, and run from thence to Cairo, through the northern end of Belleville, touching Urban, Athens and Sparta. From Sparta it will run over the fruit ridge situated between 'Campbell's Hill' and Levan's Hill, striking Big Muddy bottom, two miles west of Brownsville and thence down the Mississippi Bluffs to Alexander county, striking Santa Fee, Thebes, and so on to Cairo.
The distance from St. Louis to Cairo, as surveyed, is 140 miles. The steepest grade is 35 feet to the mile, and much of the route does not exceed 15 feet. Half the route is level or nearly so. The curvature of the Road will not exceed three degrees.
From East St. Louis to Sparta the Road will run through a thickly settled section of Country, and one of the richest agricultural sections of the State. The coal section commences about six miles this side of East St. Louis, and ends at Big Muddy River. Geologically speaking, the coal in the section indicated, underlays any pit discovered in this country, numbering 14 in the scale. The highest number in the Kentucky strata, is 12. The coal found on this route will compare favorably with the Pittsburg article.
This Road will bisect the road running from Murphysboro to Big Hill, five miles from the mines. The fruit region through which this Road will pass, is the finest in the State, unsurpassed even by those of Cobden.
The expense attending the grading of this Road will not be heavier than that paid by the I. C. R. R. on its southern end. Bridging the Cache River, is by the survey made avoided, while the I. C. R. R. crosses it twice. The highest embankment in the city will be eight feet.
The surveying party left yesterday to review a section of the Road by which it is anticipated a saving of some twelve feet can be made. That this road will be built is no longer a mooted question. Stock sufficient can easily be raised, and but little time will intervene ere every one will become satisfied of the fact.
Mr. H. Holbrook, the Assistant Engineer, left by this morning's train to join his corps, which left by the noon train on yesterday. We are indebted to him for the facts from which the above notes were deduced.
