A DECEPTIVE COW. 



The acccmpanx in{^^ illustrations are those of a cow prohibited under the 

 Milk and Dairy Supervision Act. On appearances she would be judged 

 a heavy milker. As a fact, she gave practicallv no milk, and such as was 



yielded was either purulent or curdled. The bulky appearance of the 

 udder was due to tissue enlargement (" callousing "), the result of long- 



continued sub-acute inihunin.it iun (Manimiti.s) of all the quarters. The 

 illustrations have been reproduced from photographs furnished by Mr. E. 

 A. Rvland, Dairy Super\isor.
