I would like to describe how surgery in S3 can clarify the meaning and certain properties of the Alexander polynomial 6 (t) of a knot. For example, the symmetry of 6 (t) boils down from this viewpoint to the familiar fact that the linking number of two oriented curves A, B in 3-space satisfies lk (A, B)= lk (B, A). Now 6 (t) is really a shorthand description of the homology H
