LOG-ROLLING AND OTHER BUILDING STUNTS
Of course my readers know all about geometry, but if by the rarest of chances one of them should not it will not prevent him from using that science to square the corners of his log cabin. Builders always have a ten-foot measuring rod—that is, a rod or straight stick ten feet long and marked with a line at each foot from end to end. Make your own ten-foot pole of as straight a piece of wood as you can find. With it measure six feet carefully on the log C, G ([Fig. 180]) and mark the point at O ([Fig. 180]); measure eight feet on the other log C, A ([Fig. 180]) and mark the point at N. If these measurements have been carefully made from C to O and from C to N and your corner is "square," then your ten-foot pole will reach between the two points O and N with the tips of the pole exactly touching O and N. If it does not exactly fit between N and O, either the corner is not square or you have not marked off the distances accurately on the logs. Test the measurements and if they are not found true then push your logs one way or the other until it is exactly ten feet from O to N. Then test the corner at H in the same manner.
