I am new to the HISTARCH list, but I am hoping someone out there can help me out.  My master's thesis is on a mid-nineteenth century evaporative salt works on the Texas coast (near Rockport).  I am looking for reports on other evaporative salt works from the same time period.  Also, if anyone has heard of a "Johnny Armstrong arm" windmill, it would answer a question for me.  The windmill name may be a local thing, since I have not been able to find anyone who has heard of such a device.  It was apparently used in the operation of the salt works, although in what capacity I do not know.  Any responses will be most appreciated.
