  The deep imaging of the field of an observed lensing event by a cosmic string
reveals many additional lensing events. We study the statistics of such string
lensing. We derive explicit expressions for the distributions of image
separations of lensing by a cosmic string and point out that they are quite
sensitive to parameters which characterize the cosmic string, such as the
redshift and tension of the cosmic string. Thus the statistics of string
lensing events add new important information on the cosmic string which cannot
be obtained from the detailed investigation of one lensing event.
