It seems that immediately on my arriving, Lewis set himself to excite the Indians to do the dreadful deed. He told them that he overheard the Dr. and myself consulting at night as to the most effectual way to kill off the Indians.

Such statements following like statements which have been sounding in our ears, and in the ears of Indians for years, and made with so much apparent solicitude for them, and at this time of great excitement among the Indians, on account of the measles, had doubtless much to do in bringing about the bloody tragedy. He took an active part in the murders—was seen by Mr. Camfield, from his place of retreat, to go up to the window in company with Tamtsaky, and beat them in, and soon after, to bring out goods.

Several times before Mrs. Whitman receivd her first wound, and after the doctor was senseless, Jo showd himself at the window with a gun in his hand. When Mrs. Whitman would speak to him, he would immediately go away. He brought the children down from the school room, and collected them in the kitchen, to be shot. When the chief gave orders not to shoot the children, and just as Mrs. Whitman was brought out upon the settee, where she receivd her mortal wounds, an Indian seizd Francis by the head, dragd him out from among the children, to the door of the Indian room, where Jo with his own hand, shot him.

The object of Lewis was doubtless plunder. Finley has a Cayuse, or Walla-walla wife, was campd near the doctor’s. In his lodge, the murderers held their councils during the massacre, he being at the head. He partook of the plunder, and is said by the Nez Perces, to have considerable money. The part he took in the battles at the Utilla and the Tukanan, is better known to others than myself. He is now said to be in the Flat head country.

On the 23d, three Indians died, including a child. The Dr. as usual had coffins made for them, and winding sheets prepard and assistd in burying the dead. His visits to the sick and dying, were as frequent as the severe sickness in his and the other white families would allow. It was most distressing to go into a lodge of some ten fires, and count 20 or 25, some in the midst of measles, others in the last stages of dysentery, in the midst of every kind of filth, of itself sufficient to cause sickness, with no suitable means to alleviate their almost inconceivable sufferings, with perhaps one well person to look after the wants of two sick ones. Every where the sick and dying were pointed to Jesus, and the well were urgd to prepare for death.
