year. Ninety-three rabbits were trapped and ear-tagged during a 10-day period at 
the beginning of October. Several population estimates were calculated from the 
capture and recapture data. The Schnabel (short form) estimate is 120 animals the 
geometric maximum likelihood estimate (MLE-G) is 228, and the maximum likelihood 
estimate from a regression of the logarithm of the number of individuals in a 
frequency class on frequency of capture (MLE-R) is 193. The MLE-R is regarded as 
the best method of estimation. The estimate of 193 rabbits is considerably less 
than the estimate of 279 and 278 for October and November 1969, but is similar to
