(1) In the States west of Lake Michigan no important advances have been made 

 in tlic great work of adapting fiuits to our ])eculiar climate and soil by growing 

 seedlings from the varii^ties introduced from southwest Eiirojje. nor from their seed- 

 lings originating in the Eastern or Soutliern )States. 



(2) Ourvahiable seedlings of the orchai'd and garden fruits have come from the 

 varieties introduced from east Europe or uortli Asia and from our native species. 



i'A) Methodic crossing and hybridizing have given in the past and. promise to give 

 ill the near future .more A'aluable aud certain results than we can hope for from 

 cliaiK c breeding from intermingled varieties and species.
