  Doped divalent hexaborides such as $Sr_{1-x}La_xB_6$ exhibit high \tc
ferromagnetism. We isolate a degenerate pair of $2p$-orbitals of boron with two
valence electrons, invoke electron correlation and Hund coupling, to suggest
that the undoped state is better viewed as a spin-1 Mott insulator; it is
predicted to be a type of 3d Haldane gap phase with a spin gap $\sim 0.1 eV$,
much smaller than the charge gap of $ > 1.0 eV$ seen in ARPES. The
experimentally seen high \tc `ferromagnetism' is argued to be a complex
magnetic order in disguise - either a canted 6-sublattice AFM ($\approx 120^0$)
order or its quantum melted version, a chiral spin liquid state, arising from a
type of double exchange mechanism.
