night. In the winter, there is a charming display of lights that runs the length of the park from the entrance on Harris Street to the exit on Wellington Street. John Lawson Park and Trail Located along the south bank of the Thames River, this park contains walking trails in a natural area. Accessed from Charles St. West, at the bottom of Wonham St. South. Smith's Pond Park This park is a natural area with walking trails, tall grass, and an annual fishing derby. Its location on the south side of Canterbury Street is the former site of Smith's mill pond. This pond vanished on 5 March 1976 when its swollen waters broke through the embankment supporting Smith's dam. The park was established in 2000. The park includes the ruins of the old cement dam and a new, much smaller pond, created by splitting the flow of Hall's Creek. One fork of the creek runs through the pond, the other fork alongside it. 19th-century millponds Early mills required water power, which was obtained by damming steams to create millponds and mill races. Thus, Ingersoll's first pond most likely dated from the years 1818-1819, when Thomas Ingersoll Jr. and James Ingersoll built a saw mill on the family farm, fulfilling their father's vision when he chose the site for his family in 1793. Construction of a dam, spillway, raceway and millwheel machinery and structures was a complex process, but the saw mill was finally put into operation by April 1819. This was followed by construction of a grist mill as the family ventures grew. By the 1850s Ingersoll had five ponds whose mill races delivered power to grist mills, flour mills, saw mills and a woollen mill. All five ponds were located south of the River Thames, four of them using water from two north-flowing tributaries of the Thames River and one using water from the Thames itself. Three mill ponds were located along Hall's Creek, which flowed swiftly northward from Elisha Hall's farm: Hall's Pond (later Stuart's Pond), Smith's Pond, and Smith's "lower pond" (later Partlo's Pond). To the west was Benson's Pond (later King's Pond) on Whiting Creek. Lastly, there was Carroll's pond, just south of the River Thames. To make this pond, Daniel Carroll diverted water from the west-flowing Thames to create an artificial, west-flowing creek; then he damned the creek to create the pond and mill race,
