Not long before he had discovered that one of the chief handicaps to street-railway development, on the North and West Sides, lay in the congestion of traffic at the bridges spanning the Chicago River. Between the street ends that abutted on it and connected the two sides of the city ran this amazing stream--dirty, odorous, picturesque, compact of a heavy, delightful, constantly crowding and moving boat traffic, which kept the various bridges momentarily turning, and tied up the street traffic on either side of the river until it seemed at times as though the tangle of teams and boats would never any more be straightened out. It was lovely, human, natural, Dickensesque--a fit subject for a Daumier, a Turner, or a Whistler. The idlest of bridge-tenders judged for himself when the boats and when the teams should be made to wait, and how long, while in addition to the regular pedestrians a group of idlers stood at gaze fascinated by the crowd of masts, the crush of wagons, and the picturesque tugs in the foreground below.
Cowperwood, as he sat in his light runabout, annoyed by a delay, or dashed swiftly forward to get over before a bridge turned, had long since noted that the street-car service in the North and West Sides was badly hampered. The unbroken South Side, unthreaded by a river, had no such problem, and was growing rapidly.
Because of this he was naturally interested to observe one day, in the course of his peregrinations, that there existed in two places under the Chicago River--in the first place at La Salle Street, running north and south, and in the second at Washington Street, running east and west--two now soggy and rat-infested tunnels which were never used by anybody--dark, dank, dripping affairs only vaguely lighted with oil-lamp, and oozing with water.
Upon investigation he learned that they had been built years before to accommodate this same tide of wagon traffic, which now congested at the bridges, and which even then had been rapidly rising. Being forced to pay a toll in time to which a slight toll in cash, exacted for the privilege of using a tunnel, had seemed to the investors and public infinitely to be preferred, this traffic had been offered this opportunity of avoiding the delay. However, like many another handsome commercial scheme on paper or bubbling in the human brain, the plan did not work exactly. These tunnels might have proved profitable if they had been properly built with long, low-per-cent. grades, wide roadways, and a sufficiency of light and air; but, as a matter of fact, they had not been judiciously adapted to public convenience. Norman Schryhart's father had been an investor in these tunnels, and Anson Merrill. When they had proved unprofitable, after a long period of pointless manipulation --cost, one million dollars--they had been sold to the city for exactly that sum each, it being poetically deemed that a growing city could better afford to lose so disturbing an amount than any of its humble, ambitious, and respectable citizens. That was a little affair by which members of council had profited years before; but that also is another story.
After discovering these tunnels Cowperwood walked through them several times--for though they were now boarded up, there was still an uninterrupted footpath--and wondered why they could not be utilized. It seemed to him that if the street-car traffic were heavy enough, profitable enough, and these tunnels, for a reasonable sum, could be made into a lower grade, one of the problems which now hampered the growth of the North and West Sides would be obviated. But how? He did not own the tunnels. He did not own the street-railways. The cost of leasing and rebuilding the tunnels would be enormous. Helpers and horses and extra drivers on any grade, however slight, would have to be used, and that meant an extra expense. With street-car horses as the only means of traction, and with the long, expensive grades, he was not so sure that this venture would be a profitable one.
However, in the fall of 1880, or a little earlier (when he was still very much entangled with the preliminary *** affairs that led eventually to Rita Sohlberg), he became aware of a new system of traction relating to street-cars which, together with the arrival of the arc-light, the telephone, and other inventions, seemed destined to change the character of city life entirely.
Recently in San Francisco, where the presence of hills made the movement of crowded street-railway cars exceedingly difficult, a new type of traction had been introduced--that of the cable, which was nothing more than a traveling rope of wire running over guttered wheels in a conduit, and driven by immense engines, conveniently located in adjacent stations or "power-houses." The cars carried a readily manipulated "grip-lever," or steel hand, which reached down through a slot into a conduit and "gripped" the moving cable.
This invention solved the problem of hauling heavily laden street-cars up and down steep grades. About the same time he also heard, in a roundabout way, that the Chicago City Railway, of which Schryhart and Merrill were the principal owners, was about to introduce this mode of traction on its lines--to cable State Street, and attach the cars of other lines running farther out into unprofitable districts as "trailers." At once the solution of the North and West Side problems flashed upon him--cables.
