A closure on the discussion of the authors' paper is presented. Previous studies have diagnosed the landslide in Miocine clay in the Florida panhandle as a flow slide in an incompletly indurated sediment, similar to very sensitive Leda clays of the St. Lawrence Valley. The discussor arguges that although the failure is similar, the Hawthorne Formation underlying the site of the failure is made up of complex calcareous formations of soft sandy limestones and stiff clays. The upper part is non-calcareous soil ranging from a sandy clay to a clayey sand. Therefore, the discussor states that previous characterization of the slide in either loose sand or sensitive clay is not reasonable. The discussor agrees with other successful application of shallow foundations supported directly on porous Miami Dolite. However, it is noted that one should not rely on the integrity of Oolite crust without considering either the material beneath the crust or the weakness in the crust. An additional discussion of the structural settlement of a building in Florida is presented. The discussor concludes that both successes and failures must be carefully considered by the geotechnical engineer in evolving a safe economical design. Blind rules are inadequate; a realistic analysis must be made of the actual site conditions. Lastly, in any evaluation of soil bearing, the underlying strata must be considered as well as the material on which the foundation rests.
