The effect of a trailing or longitudinal vortex on shear flow near a wall is investigated on the basis of exact equations. It is found that the vortex tunnels under and across the shear flow, lifting the flow away from the wall by an amount depending on the distance of the vortex from the wall but not on its strength. Some conjectures are made concerning the behavior of pairs and groups of longitudinal vortices.
