Both Maricopas and Pimas fully believed that all sickness and calamities of any kind were caused by witches. Their witch doctors claim the power to divine who the witches are. When this is done all hands turn out with clubs and stones and kill the poor wretch pointed out. Whenever there is much sickness among them some one has to die as a witch. This I had endeavored to check by teaching them better, but I soon learned that my teaching had not reached the desire, as witches were killed among those settling with us of the Maricopas.
I went to their camp and told old Malia, who was quite intelligent in many respects, that if such an act occurred again that I would deliver them to the law to be dealt with as murderers. At the same time explaining to his people the general laws of health, showing them that the violation of natural laws produced sickness.
Some time after this a Maricopa woman came and told my wife that the Maricopas had decided to kill me; that the witches were killing their children and that I would not allow them to kill the witches. So the only way to protect the lives of their children would be to kill me, as I was a friend of the witches.
When I came home my wife told me of this threat. She seemed a little concerned for my welfare, but her faith was always with mine; so we decided that it would be best for me to go at once and put a stop to this feeling.
I got on my horse and went alone some three miles to their camp. Most of the Indians were gathered together. As I approached none spoke; all were sullen. This confirmed to me the truth of the squaw's report, as the Indians generally met me in a friendly manner.
I went directly to the subject; told them what I had heard, saying to them that I had no fears of their killing me and that there was no use for them to entertain any such feeling towards me, for I was their friend and teaching them the truth, and that God would protect me. I again talked to them a long time and finally seemed to gain some influence.
The Pimas had also been guilty of the same practice. When I heard of this I took a good interpreter and went to their camp, which was across the river among the old settlers not of our colonizers.
I had to labor long and hard before getting any satisfactory results. The old chief acknowledged that they had killed one witch and had almost killed another, who had recovered, and that they were then doctoring him to cure him, so that all hands could turn out and "kill him better."
I asked how they knew these men were witches. The answer was that the "doctor" had pointed them out.
I asked to see this "doctor" This was declined. I insisted, telling the chief that I would neither befriend him nor his people, nor talk to them about anything more until this "doctor" was shown me.
