  The CANGAROO experiment has observed gamma-ray above 7TeV from the Crab
pulsar/nebula at large zenith angle in Woomera, South Australia. We report the
CANGAROO data taken in 1992, 1993 and 1995, from which it appears that the
energy spectrum extends at least up to 50 TeV. The observed integral spectrum
is (8.4+-1.0) x 10^{-13}(E/7 TeV)^(-1.53+-0.15)cm^{-2}s^{-1} between 7 TeV and
50 TeV. In November 1996, the 3.8m mirror was recoated in Australia, and its
reflectivity was improved to be about 90% as twice as before. Due to this
recoating, the threshold energy of ~4 TeV for gamma rays has been attained in
the observation of the Crab at large zenith angle. Here we also report the
preliminary result taken in 1996.
