Authors abstract: In 1977 Gerard Duminy proved that, if \(F\) is a semiproper leaf of a \(C^{2}\) codimension one foliation \(\mathcal{F}\) of a compact \(n\)-manifold \(M\) and \(X\) is an exceptional local minimal set of \(\mathcal{F}\), then the set \(\mathcal{E}^{X}\left( F\right) \) of ends of \(F\) asymptotic to \(X,\) if nonempty, is homeomorphic to a Cantor set. No proof of this remarkable result has ever appeared, even in preprint form. Here, we offer a proof of our own.
