UKE ADDING JUtfOTHER 

 COW TO YOUR HERD 





X HAT flytime let-down is a "checkoflF" 

 you hate to pay. It benefits nobody. Per- 

 haps another cow would help. But preven- 

 tion is cheaper. Mrs. Cow will pay more 

 for your grains and concentrates when 

 pastures get short if she has plenty of 

 water . . . good shade . . . and a spray with 

 BLUE SEAL twice a day to keep flies away. 

 BLUE SEAL "knocks flies dead." Thou- 

 sands of Illinois dairymen will tell you 



that — they used 51,777 gallons last sea- 

 son. It is easy to apply with a BLUE SEAL 

 continuous sprayer. It is safe, clean and 

 economical. 



»3TART now — a dead fly now means a 

 million less in July. BLUE SEAL is 

 reasonable in 5-gallon drums. Call your 

 Service Company Salesman who drives a 

 BLUE and White Tank Truck 



Is your old sprayer in working order?
