Morison, consulting engineer, whose work on the bridges across our great rivers is notable for its strength, simplicity, and finished appearance. In a lecture he described the process of the design of some large piers: "Fourteen years ago I had occasion to design a bridge pier for a bridge across one of our Western rivers, and I tried to make an ornamental pier. When the plans were completed I did not like them. One change after another was made, all tending to simplicity. Finally the plans were dpne. From high water down, the pier was adapted to pass the water with the least disturbance; it had parallel sides and the ends were formed of two circular arcs meeting. Above high water the ends were made semicircular instead of being pointed. The pier was built throughout with a batter of one in twenty-four. A coping 2 feet wider than the body of the pier projected far enough to shed water, and the projection was divided between the coping and the course below. Another coping with a less projection surmounted the pointed ends where the shape was changed. It was as simple a pier as could be built, and in every way fitted to do its duty. I had started to make a handsome pier. The pier that was exactly what was wanted for the work was the only one that satisfied the demands of beauty. Forty-three piers of precisely this design, no change having been made except in the varying dimensions required for different structures, besides eight others in which only the lower parts are modified, are now standing in eleven different bridges across three great Western rivers.
