An equilibrium situation is obtained for the case of a uniform axial magnetic field with the addition of a superposition of weak helically invariant fields, a field due to a small axial current, and a field due to a lowpressure infinitely conducting plasma. The energy prin- cipal is used to determine conditions for the stability of this equillbrium. Two basic results are obtained: (a) the conditions for the stability of a system which consists of a superposition of helical fields and"bulge'' fields (l = 0) are determined; and (b) it is shown that the addition of a helical field with 1 = 3 can produce complete hydromagnetic stability when an axial current is flowing and can also increase the Kruskal limit on the current for the m = 1 mole.
