Your’s of the 16th. was recieved by last post. I should certainly prefer Walnut for the Bedford sashes, because well rubbed on the inside & unpainted it has a richer look than a painted sash, and I believe no wood is more durable but if you cannot get it good, then certainly good pine will be preferable to bad walnut. it must therefore depend on your being able to get good walnut & without delaying the work. The sashes for the lower rooms may be of pine. I salute you with esteem.
