[Cob] purpose of straw in cobpaul dotpaul at paulleblanc.netThu Jul 12 20:35:07 CDT 2007
Well, I wouldn't know from experience, Damon, but I've heard tell the term "tensile strength". Hmph, tensile. It figures. I suppose tensile is different than tinsel, but I don't know how. Can you hang tensile on a tree? That's my technical analysis for this summer. paul ----- Original Message ----- From: "Damon Howell" <dhowell at pickensprogress.com> To: <coblist at deatech.com> Sent: Thursday, July 12, 2007 1:20 PM Subject: [Cob] purpose of straw in cob > What is the purpose of straw in a cob mix?
