 In part, he used the eagle's extraordinary dimensions (and the artistic skills of John Karl Daniels) to cast eight concrete look-alikes, that now sit atop the tower to watch over their former domain.In addition, eight "Guardians of Health" were placed around the tower (one under each eagle), to prevent any bad-tasting or bad-smelling water pollutants from contaminating the water supply, which were believed to be the cause of many typhoid fever outbreaks around that time.Jones's house is located near the tower.
