Query: Identifying logarithmic tracts   We show that a direct tract bounded by a simple curve is a logarithmic tract
and further give sufficient conditions for a direct tract to contain
logarithmic tracts. As an application of these results, an example of a
function with infinitely many direct singularities, but no logarithmic
singularity over any finite value, is shown to be in the Eremenko-Lyubich
class.
