A.M. rode with President Joseph and brother Neibaur to Doctor [Robert] Fosters. He was gone to appanose and his wife was at Mr. Gilmans. We went down there and saw her. President Joseph asked Sister Foster if she ever in her life knew him guilty of an immoral or indecent act. She answered no. He then explained his reasons for asking and then asked if ever he had used any indecent or insulting language to her, she answered, never. He further asked if he ever preached any thing like the spiritual wife doctrine to her only what he had preached in public. She said no! He asked her if he ever proposed to have illicit intercourse with her and especially when he took dinner during the Doctors absence. She said no. After some further conversation on the subject we left. Mrs. Gilman was present all the time.
