Hi all- I came across the work of Dr. George Washington Carver while trying to find how to store sweet potatoes in hot & humid Dallas, TX. I searched permies.com and I can't find the same references, so in the interest of "spreading the love" I'm posting it here- I apologize if it turns out this is redundant.
Anyway, a librarian at Tuskegee University Library found me one set of the early 20th-century bulletins issued by Dr. George Washington Carver. In addition to many other subjects of interest, Dr. Carver wrote of his sweet potato experiments at the original Tuskegee Agricultural Station, which happens to be in Alabama on the same zone that I'm in, currently ranked as 8a, and experienced a lot of the same weather patterns as Dallas does now. Here's the Library's link, as well as a few others that I've found:

UC Davis bundle of bulletins 1905 - 1916 (I include these since they don't have the distracting Tuskegee watermark on the pages, and download as one big file):

Weather records kept by Dr. Carver, to doublecheck that his weather of a century ago approximates Dallas, TX weather today:
