  Recent findings indicate that the Monogem Ring supernova remnant (SNR) and
the associated pulsar B0656+14 may be the 'Single Source' responsible for the
knee in the cosmic ray (CR) energy spectrum at ~3 PeV. We estimate the
contribution of this pulsar to CR in the PeV region. We conclude that although
the pulsar can contribute to the formation of the knee, it cannot be the
domimant source and a SNR is still needed. We also examine the possibility of
the pulsar giving the peak of the extensive air shower (EAS) intensity observed
from the region inside the Monogem Ring. If the experimental EAS results
concerning a narrow source are confirmed, they can be important, since they
give evidence: (i) for the acceleration of protons and heavier nuclei by the
pulsar; (ii) for the existence of the confinement mechanism in SNR; (iii) that
CR produced by the Monogem Ring SNR and associated pulsar B0656+14 were
released recently giving rise to the formation of the knee and the observed
narrow peak in the EAS intensity; (iv) for the Monogem Ring and the associated
pulsar B0656+14 being identified as the Single Source proposed in our Single
Source Model of the knee. A number of predictions of the examined scenario are
made.
