- Erection of a Cantilever
The new bridge at Poughkeepsie has three of these cantilevers, connected by two fixed spans, as shown in the illustration. The fixed spans have horizontal lower chords, and really extend beyond each pier and up the inclined portions, to where the bottom chord of the cantilever is horizontal. At these points the junctions between the spans are made, and arranged in such a way, by means of movable links, that expansion and contraction due to changes of temperature can take place. The fixed spans are 525 feet long. Their upper chord, where the tracks are placed, is 212 feet above water. These spans required stagings to build them upon. These stagings were 220 feet above water, and rested on piles, driven through 60 feet of water and 60 feet of mud, making the whole height of the temporary staging 332 feet, or within 30 feet of the height of Trinity Church steeple, in New York. The[35] time occupied in building one of these stagings and then erecting the steel-work upon it was about four months. The cantilever spans were erected without any stagings at all below, and entirely from the two overhead travelling scaffolds, shown in the engraving. These scaffolds were moved out daily from the place of beginning over the piers, until they met in the centre. The workmen hoisted up the different pieces of steel from a barge in the river below and put them into place, using suspended planks to walk upon. The time saved by this method was so great that one of these spans of 548 feet long was erected in less than four weeks, or one-seventh of the time which would have been required if stagings had been used. - Soldiers' Monument at Buffalo, N.

- Jim Bridger
The remaining three expeditions were guided by James Bridger, who in 1843 had set up Fort Bridger on Black’s Fork of Green River, to cater to the emigrants who were beginning to follow the Oregon Trail. James Gemmell claims to have been among those present in 1846 when Bridger led “a trading expedition to the Crows and Sioux,” north up the Green River through Jackson’s Hole to West 78Thumb, making a tour of the “wonderful spouting springs” and other scenic features before continuing down the Yellowstone. E. S. Topping states that in 1850 Jim Bridger, Kit Carson, and twenty-two others on a prospecting trip out of St. Louis “crossed the mountains to the Yellowstone and down it to the lake and the falls; then across the Divide to the Madison River. They saw the geysers of the lower basin and named the river that drains them the Fire Hole.... The report of this party made quite a stir in St. Louis.” - State Street and Capitol, Albany, N. Y.

- Fall of Table Rock
On the 25th of June, 1850, occurred the great downfall which reduced Table Rock to a narrow bench along the bank. The portion which fell was one immense solid rock two hundred feet long, sixty feet wide, and one hundred feet deep where it separated from the bank. The noise of the crash was heard like muffled thunder for miles around. Fortunately it fell at noonday, when but few people were out, and no lives were lost. The driver of an omnibus, who had taken off his horses for their midday feed, and was washing his vehicle, felt the preliminary cracking and escaped, the vehicle itself being plunged into the gulf below.
