shell. Figure 43 shows them on the shell about 

 their real size. These are the same kind that 

 attacked me. A soft-skinned person must be a 

 very juicy morsel to animals that can success-

The ticks are a great hindrance to cattle 

 growers. Fresh milk on the Canal Zone costs 

 thirty cents a quart, so that most people use 

 dried or condensed milk instead. This is because 

 the orood milk cows we have in the north cannot 

 live in the pastures of Panama on account of the 

 ticks. The ticks not only weaken the cattle by 

 sucking their blood, but they carry a disease that 

 kills many of them. The cattle grown on the 

 ranches owned by the government on the Zone 

 are of the small native breeds that do not suffer 

 from disease as the better northern cattle do.
