Thanks to Granda, Blinky Bill, Dan Breen, Gary & Elizabeth Kent, Jim Roberts, Iris, V. Dawson, Susan Whelan and Don Tate for your help in figuring out the old conversions on this antique measuring tape from Newfoundland. I now know that the entire tape of 66 feet measures one chain and that there were 10 square chains in an acre. Each chain was made up of 100 Links or 4 Poles (which is the same as a perch or rod). Apparently, this was the old way of measuring land and some people have suggested that what I have inherited is a land surveyor's measuring tape. One person told me that my T shaped awl is a "hole borer" but I am still not sure what it was used for. Anyone have more to offer on that one? I can send you a picture if it would help. How about dating these tools? Any suggestions there? Again, thanks for your help! I can always count on my genealogy friends to come through with the correct answers! Valerie
