Guided by the early discoveries of Nickerson1 (1906), the place selected for the work was the lake region in the northeastern part of the state.The history of this parasite in North America is concisely given in my2 chapter on animal parasites in Abt's Pediatrics. The record of the plan for the study of the problem may be found elsewhere in a brief paper of mine.3The summer's work I had laid out carefully and it was carried out substantially as planned. By the courtesy of the school board at Ely we were permitted to use the biologic laboratory of the high school for our work
