[30] As early as 1901, C. E. Grunsky, at that time City Engineer, was directed by the Board of Supervisors to gather data on the operation of electric roads under the conduit system. Grunsky's findings were to the effect that conduit-electric roads were rapidly replacing other types of street railroads. The city also employed J. C. H. Stutt as consulting engineer, and sent him to New York and Washington to inspect and report upon the conduit systems in operation in those cities. He reported that the system was giving satisfaction in both cities, and in many cases was being substituted for the trolley. Engineer Stutt in comparing the two systems said: "As between the overhead system and the conduit-electric system, it is natural for private corporations to prefer the overhead trolley system on account of the first cost of roadbed construction, which is more than twice as great for the conduit system. The conduit system leaves the street open with the view unobstructed by poles, conductors, feed, guard and supporting wires and without the menace to the public and especially to the firemen, always inherent in the bare overhead electric conductor." This report was widely quoted during the overhead-trolley-conduit agitation that was a feature of a greater part of Mayor Schmitz's administrations. [31] Mr. Parsons found for the overhead trolley on the following general grounds: (1) That a uniform system was necessary. (2) That the lines must be extended to the suburbs. (3) That operation by overhead trolley is more satisfactory than by the conduit system. (4) That the greater part of the roads could be operated under trolley only. [32] Several questions were presented. The following is the vote as given in the Merchants' Association Review, the organization's official publication, for February, 1906: "TOTAL VOTE OF MEMBERS, 364. "1--Do you favor Mr. Parsons's view of a uniform system of overhead trolley lines throughout the entire city, including a central line of ornamental trolley poles, with lights furnished by the Railroad company between the tracks on Market Street, and a trolley line with ornamental poles and lights furnished by the Railroad upon Sutter Street? "Votes received--Yes, 121; No, 204. "2--Do you favor an overhead trolley system throughout the city except on Market Street? "Votes received--Yes, 67; No, 212. "3--Do you favor an underground conduit system for Market Street and for the streets with cable lines leading into Market Street in the central downtown district and in the adjacent residence district, the remainder of the system to be overhead trolley?
