Lets test your drill holes to see if they are Spanish. OK? First, look very close and see if the hole is actually round or is there an ever so small V cut on the top of the hole itself. It will be very small and you may not notice it at first so look close. Now if you do see something that looks like a tiny pointer then go in that direction enactly 100 Spanish varas (90 American yards). If you need to contact me do so at bllayton@yahoo.com Lou Layton
