Forms part of Fonds 1, City of Winnipeg (1874-1971): Series 82 consists of items contained in a casket prepared by City Council for placement in the cornerstone of the City's first city hall.

Not long after incorporation, City Council proposed construction of a city hall. A site on Main Street between William and Market Avenues was selected. On August 17, 1875, the cornerstone of the new city hall was laid with Masonic honors by Grand Master the Rev. Dr. Clark and officers of the Grand Lodge. A civic holiday was declared to mark the occasion, and speeches were made by Chief Justice Wood, the Hon. R. S. Davis, Premier of Manitoba, and American Consul James Wickes Taylor. At the ceremony, a casket was deposited into the cornerstone ' the casket contained coins, bills, newspapers and photographs of the City. Today, such a box would be called a time capsule.

Completed in 1876 and formally opened on March 14 of that year, the first city hall suffered chronic structural problems. Repairs were attempted, but were not successful, and for some time, the building was propped up with wooden braces until it was finally judged unsound and demolished in 1883. At demolition, the casket was removed and eventually placed into the cornerstone of the second city hall. When this building was demolished in 1962, the caskets were moved to a bank safety deposit box and then to the Archives.
