California (California Y/eckly News Letter, Volume 3, No» 34). "During the 
eighteen months ending June, 1922, this disease necessitated the 
dipping of 2,102,000 sheep* Making a conservative estimate that 
dipping costs five cents per head ; this item alone amounted to 
^105,000. Since a great ecor>onic loss to sho^p rner. can be 
prevented annually by eradicating this disease, most stringent 
methods should be put into effect."
