II. In the year 1871 a corporation known as the Des Moines Water Company was organized for the purpose of building and operating waterworks in the city of Des Moines. On the first day of May of that year, the city council passed an ordinance by which the said company was authorized to build, maintain, and operate waterworks in the city, to supply the said city and its inhabitants with pure and wholesome filtered water, and to use the streets, alleys, and avenues of the city for the purpose of laying the water pipes neces sary to convey the water throughout the city. This ordinance provided that said water company should have the exclusive right to construct and operate their works for the term of forty years. It is not necessary to set out the ordinance at length in this opinion.
