  A discussion is given of the confinement mechanism in terms of the Abelian
projection scheme, for a general number Nc of colors. There is a difficulty in
the Nc to infinity limit that requires a careful treatment, as the charges of
the condensing magnetic monopoles tend to infinity. We suggest that Bose
condensation of electric or magnetic charges is indicative for the kind of
confinement that takes place, but the actual mechanism of confinement depends
on other features as well.
