From the reviews: "The book under review is one of five or six books on foliations that should be in the professional library of every geometer. ... authors define the fundamental tensors of a Riemannian submersion tensors that carry over to a metric foliation on M ... . gives a brief introduction to the geometry of the second tangent bundle and related topics needed for the study of metric foliations on compact space forms of non negative sectional curvature ... ."
