Abstract: The peculiar properties of the $ {2^j} - 2$ dimensional generators of unitary bordism (the $ 2$-primary Milnor generators) are related to the $ {2^j} - 3$ dimensional indecomposable torsion classes of Alexander. This result is then used to confirm a conjecture of Ray concerning the generalised homology spectral sequence for $ MS{p_\ast }(MU)$. Finally it is noted that Ray's conjecture to the effect that all classes in $ MS{p_\ast }$ are detectable by KO-characteristic numbers must fail.
