gis1o Ruiy to conids    st   of rabbtsde r the R woseey 
Xear Sill, an  sugesting parllel rabbit studies in Canad.      I wa 
aske to see you. persnoally to present the arigwots in favor of this 
sugestion. I tried to do this. but by th  tins I had gottenaroun 
to It I found you. had left tows. Carlos Avery now r~ests that I 
pre~set the a&pm~t M* wal as possibl by mai. 
 
        Th C&adianIconcrus, primarily the as.nows     rabt    You 
are familiar, of cours, with the various Canaian authouities wh 
-e  in wind. the existseas of a popuation cycle In snowshe rabbits. 
in mySm  survy of Wisconsin I found that this cycle coincided 
qu11. strongy with the grose cycle, but %bat the severty of vtrgo 
1eno of the cycle seme to vary a ge~at d~ between localit ies. 
Th  first r"*stioa I wol mak      t the aie& of an b$.irto  iea
 stu 
in Canada todtermine the extent to which the snomhos rabit eycl 
is #ot~si&Ita in scope and to uht extent the seveitty an vrlfe 
of the eyele varies as bstvon eg ions and 1..4lti~s.     I know that s*m

Soth of these piecs of wr are so nearly Canaaila     in their g
