The company’s principal lines were operated by the cable system. But fully five years before the fire, all traction officials as well as the general public, recognized that San Francisco had outgrown the cable road. It was admitted that electric lines must be substituted for the cable, but there was sharp division as to the character of the electric lines which should be installed. The officials of the United Railroads proposed the overhead trolley method of propulsion; the public, so far as it could find expression, declared for the underground conduit system.[29] In taking this position, the public was in reality backing up the municipal engineers, who had been sent to Eastern States to investigate electric transportation systems, and who had found in favor of the conduit and against the trolley.[30]

The San Francisco Merchants’ Association, however, apparently dissatisfied with the reports of the engineers employed by the municipality, employed Mr. William Barclay Parsons to report on the relative merits of the trolley and the conduit systems.

Mr. Parsons took issue with the city’s engineers, and recommended the trolley as against the conduit.[31] The directors of the Merchants’ Association thereupon declared for the trolley system.

Criticism of this action of the directors was followed by submission of the question to a referendum vote of the Association membership. The members voted in opposition to the directors, declaring against the trolley and for the conduit.[32]

But the most determined opposition to the installation of the trolley system came from improvement clubs, whose purpose was to promote the best development of San Francisco.

Prominent among these organizations were the Improvement and Adornment Association,[33] the Sutter Street Improvement Club[34] and the Pacific Avenue Improvement Club. The membership of these organizations consisted of some of the largest owners of San Francisco properties. The leaders were comparatively young men, natives of San Francisco, whose interests were inseparably wrapped up in the community, and who aimed to promote the best possible development of the city of their birth and fortunes.

Prominent in this group were Rudolph Spreckels[35] and James D. Phelan,[36] rated among the heaviest property-owners of San Francisco. These men were ready to join with the United Railroads in any plan which proposed the highest development of the street-car service.[37] On the other hand, they were prepared to oppose any attempt to exploit the service to the detriment of San Francisco.[38]

A conference of the directors of the Improvement and Adornment Association with officials of the United Railroads was finally arranged.[39] The meetings were held in March, 1906, less than a month before the great fire. There were, before the attempted adjustment was abandoned, several sessions.

The citizens urged Patrick Calhoun, president of the United Railroads, to give up his trolley design for Market and Sutter streets. As a compromise, he substantially agreed to build the underground conduit as far as Powell on Sutter, and as far as Valencia on Market, picking up the trolley on Valencia, McAllister, Hayes and Haight streets. The Adornment Committee directors wanted the conduit system on Sutter street extended as far as possible, and held out for Van Ness avenue. Calhoun would not consent to install the conduit beyond Powell.

In the midst of this deadlock, the San Francisco Chronicle published what purported to be reports of the several conferences. Up to that time there had been no publication of the meetings.
