These figures must not be taken as complete indica- 

 tion of relative prevalence of dairying in the regions 

 indicated because San Francisco draws market milk 

 away from manufacture in Region 2, Los Angeles 

 does the same in Region 3, and both cities receive 

 milk from Region 4. The compilation, however, 

 shows that the chief dairying is now done in the 

 great interior valleys of Region 4 where meteorologi- 

 cal conditions were held forty years ago to be prac- 

 tically prohibitive of commercial dairying. The tab- 

 ulation indicates the great geographical range of the 

 dairy industry. Of the three counties which lead in 

 production, Humboldt is on the coast in the extreme 

 northwest corner of the State; Stanislaus is in the 

 great valley in the center and Imperial is in the 

 extreme southeast corner and 725 miles distant in 

 an air-line from Humboldt. Divergence in conditions 

 is as great as in distance, for dairying in Humboldt 

 is done in a cool ocean atmosphere entirely by rain- 

 fall vegetation while in Imperial there is practically
