“ This being the case, it is evident that no deprivation of property without due process of law or impairment of the obligations of a contract did or could arise from the act of the legislature empowering the city to erect its own waterworks. Having this power, the legislature could therefore have exercised it without compelling the city to buy the plant of the water company, and the bill proceeds upon the theory that if this right had been exerted by the legislature the company would have been ruined, and the value of its property in effect entirely destroyed. ”

“ To indulge in the assumption that the action of the company was not voluntary would require the assumption that the company would have willingly suffered a most grievous wrong when, by accepting as it did the benefits of the act, such consequences were averted. ”

“ No compulsion in any legal sense can be said to have been exerted on the company by the option given it, because the exercise by the company of the option, upon its own theory of the case, saved its property from destruction. ”
