To understand why It was done, one mint take a look at the general organization of a railroad's working force. Primarily railroads are built to earn money for their ownurs. This Is certainly the mission of tho Union I'aeillc under Its present iiiiiiianu inent. To earn money thu road must be properly constructed, equipped and manned.

Only In one way can this bo done. That Is lo reduce the Ki'mles. Tho power of a locomotive, like that of a horse, Is limited by the maximum acclivity of the route over which It travels. If this maximum bo reduced, then the power Is lncieascd. The iilcstlou Is one for debate K1S1I CUT. WllKltK T1IK KOSSILS and adjustment between the departments of t lit road. On the Union I'aeillc It was re solved not lung after the accession of thu present management by the determination to cut down the almost Inaccessible asceni to Sherman Hill, the highest point on th Union 1'aclllc line, ,is well as the heaviest, made (leneral Sher man oucu re marked In talk ing over thu mat ter: "lly a stroke of Junius thu builders of the Union 1 a c 111 c surmounted t h e Itocky mountains by u grade of about eighty feet to tho mile, whereas by any other route then known they would havu been forced to grade l!uo feet or to adopt short curves through Laramie pass." In thU statement moru than u measure of truth appears, and yet it may be doubted If It was exactly a stroke of genius that so for tunately lo'atcd the line. The stubborn fact Is that lieneral (iiciivillo M. Dndgc, who was in charge of the pioneer work on the Hue. got lost from his party, and In wandering about discovered the pass that was hUbsciiieutly used acloss the Ito 'kles.

One i f lliese necessitated the solu tion of the lower grade question and tho straightening f thu Hack. One hundred ami llfly-eight and four-tenths miles of new track were laid, reducing the mileage between Omaha and Ogden by 3tl.IT miles, and reducing gradients which varied from la, I to U7.GS feet to thu mllu to a maximum of 43.3 feet. Tills is thu simple talu of what has been done. It was the doing of it that is 'I-""" '!.;' ' ' V interest. Hvur s I n c u thu original survey of the Union I'aeillc, which was Itself considered a marvel of tho kind, was complettd, It has been the understanding that by doing a little heavy grading work here and there, cutting out curves, and thu Uku, (he gradu could be lowered nnd the distance short ened. As management succeeded manage, incut In control of the road, (he proposition received attention, but never took an active form until the present owners took over the properly. When their new presi dent, Mr. Hurt, assumed charge he began without delay an extensive cam paign of betterment. In this was In cluded the Improvement of the road bed, and the Wyoming work was soon de termined upon. Several surveying partb's were put Into the Held to determine tho possible cutoffs, and about n year ago work was commenced in enrnest on what to tho lay mind seems a stupendous task, hut to the engineer a mem matter of detail. Klrst i'lll-ec ( llttitlx. The first three cutoffs authorized and built were those between Laramie and Itawllns. These are known as "Howell to 1111110118," "Lookout to Medicine How." nnd Allen Junction to liana," Involving tin construction of abt.iit fifty miles f line and accomplishing n suvlng In dlstnnco of practically nineteen miles. The rcdiuti a In grades was from seventy-live feet to forty-three feet per mile. All of this was heavy work. Klght miles of the heaviest portion, Just west of Hanna, Involved thu moving of approximately 1,700,000 cubic yards of material, of which nearly 1,310. ono cubic yards was embankment and 310, 0' 0 cubit yards s lid nek excavation.

Kroni a constructive standpoint the line Is remark able for the amount of material required In tho construction of iniinensu embank nientH nnd the building of largo tunnels through solid rock.

One of the singular fea tures of the work was tho handling of broken rock xvlth the steam shovel. Enor moiis pieces of granite, brought down by the blasts, wore loaded on tho curs by tho steam shovel, ami in fact the results wore as satisfactory in thu rock cutH as on tho dirt work. At one time on thes cutolf lines or the Union I'aeillc there xveru llftoen steam shovels at work. Nearly all of the heaviest work was handled with i-te.iin shovels. Much of the "borrow" work for tho heaviest embankments was done by means of sleam shovels and dump cars. An Interesting feature of the engineering tvork Is tho culverts.
