Letter from Harris Leon Kempner to Shrub enclosing a postcard. He mentions that their trip to New Orleans has been cancelled due to the weather, and weather has been magnificent yesterday and today so they went to sailing. And as Shrub has the typewriter now, Harris suggests him to use it to write letters though the phone was great, they'd like to hear more.
