When Seattle streets were regraded, supported residences were either lowered with a jack or given a new first floor with a new foundation.

IN THIS DISRUPTED street scene we get a fine lesson in how homes were propped up while the ground below them was removed during street regrades — here at Spring Street and Fifth Avenue.

St. Francis Hall, the institution on the far right, was built in 1890-91 by the Rev. Francis Xavier Prefontaine. Seattle’s first Catholic priest was known as much for his street savvy as for his pulpit homilies. Prefontaine rented his new hall first to Jesuits for their original incarnation of Seattle Prep, but then to many others, including the Knights of Columbus, the Catholic Foresters, dance instructor Professor Ourat (from Florence) and the Andante Non Troppo Club, also for dance.
