Sanatorium (Location Key)

After Mrs. Hightower breaks down in church, the Presbyterian congregation raises funds to send her to "an institution, a sanatorium" (65). Hightower visits her "every two weeks" during her confinement there, but since he returns to Jefferson each time "after a day or so," it cannot be very far from Yoknapatawpha. And although the Mississippi State Insane Asylum at Jackson appears in a number of fictions, it's always called an 'asylum,' not a 'sanatorium.' So presumably Faulkner is thinking of a private facility somewhere in Mississippi.
