Whitlock finds that chiggers are also verytroublesome to young fowls, especially small has observed the parasites collected in lumps aslarge as the head of a pin, and has seen as many as adozen such lumps on one chicken not two weeks old. Hefurther states that in such cases the chick generally diespromptly. He reports the case of a chick dying after anumber of tetanic spasms, lasting for perhaps an the chigger {Leptus Irritans). 250 diameters. There is a great difference in the degree of suscepti-bility of different persons to these parasites. Severalpersons have assured me that they are never attackedby chiggers, bed-bugs, fleas and ticks.
