  The bootstrap current and flow velocity of a low-collisionality stellarator
plasma are calculated. As far as possible, the analysis is carried out in a
uniform way across all low-collisionality regimes in general stellarator
geometry, assuming only that the confinement is good enough that the plasma is
approximately in local thermodynamic equilibrium. It is found that conventional
expressions for the ion flow speed and bootstrap current in the
low-collisionality limit are accurate only in the $1/\nu$-collisionality regime
and need to be modified in the $\sqrt{\nu}$-regime. The correction due to
finite collisionality is also discussed and is found to scale as $\nu^{2/5}$.
