Query: On the axiomatisability of the dual of compact ordered spaces   We provide a direct and elementary proof of the fact that the category of
Nachbin's compact ordered spaces is dually equivalent to an Aleph_1-ary variety
of algebras. Further, we show that Aleph_1 is a sharp bound: compact ordered
spaces are not dually equivalent to any SP-class of finitary algebras.
