 symptom of this disease. Young cattle -ticks will be 

 found on the belly, inside of the thighs, on the fore- 

 legs or brisket. They are very small, and a close 

 examination is often necessary to reveal them.

 hot sun. If they will eat, laxative green food may be 

 given, such as green corn -fodder. Drenching sick 

 cattle with sweet milk is also to be recommended.

 during cold weather. The ticks are destroyed by the 

 cold as soon as they drop from the bodies of cattle, 

 or the eggs are destroyed, so that no young ticks hatch. 

 If the ticks are all removed from southern cattle, the 

 latter do not communicate the disease. Dipping south-
