The people are often assured that these false figures of capitalization are merely romantic and do them no harm, because charges must be governed by the "laws of trade." One of the "laws of trade" that regulates the "market price" of such commodities as transportation, light, water, gas, furnished by the help of the public franchises, is the power of the public to regulate. This public power depends upon the public knowledge and the public disposition. To make the public believe that the profit of serving it has been only 3 per cent. a year, when it has been nearer 50 per cent., is to manipulate public opinion, the most potent of all the "laws of trade," for a competing supply cannot be got easily, often not at all. A committee of citizens were invited by the representatives of the gas companies to meet them to verify the statements of the companies as to the unprofitableness of the business, and the inexpediency of municipal self-supply. But when the committee wanted to know what had been the real cost of the private pipe lines, on the $6,000,000 nominal capital of which the people were expected to pay dividends, they could not get any satisfaction. The companies would only give an estimate. To the request for more definite information, the reply of both companies was, "We have not got the books of the contractors; we have never had them. We have no means of knowing the actual cost of the Toledo plant, or any books to show it.[550] We have no papers or documents in regard to the construction of this line." It came to light later that one of the companies in the oil trust had constructed the pipe line for the gas company, and at a price approximating the large figures claimed. The company that built this pipe line is a ring within the oil and gas ring, always on hand for such contracts and at like margins of profit, and it is owned almost wholly by the principals of the combination.[551] The people--mostly Ohioans--who took the minority 40 per cent. of stock of the gas company were really the "simple greens." All that was paid for this construction by those who were members both of the inside ring and the gas company came back to them; their associates in the minority paid, but got nothing back. It was from the latter came the profits of this contract to the insiders.
