Query: Islands in the Stream of Hawking Radiation   We consider the island formula for the entropy of subsets of the Hawking
radiation in the adiabatic limit where the evaporation is very slow. We find a
simple concrete `on-shell' formula for the generalized entropy which involves
the image of the island out in the stream of radiation, the `island in the
stream'. The resulting recipe for the entropy allows us to calculate the
quantum information properties of the radiation and verify various constraints
including the Araki-Lieb inequality and strong subadditivity.
