Every once in a while there seems an eruption of some silly debate which goes on for months and months, writers taking hours on hours to write their opinions, and readers days and days to study them, when five minutes of a personal examination would settle the whole question. Just now the old topic, Do tree trunks elongate? is again the subject of contention, though it was thought to be respectably buried over a dozen years ago. "Well, do they?" Go to the nearest Norway Spruce or Pine tree on your lawn, and you will find the lower branches or their scars a few inches from the ground, just where they were when you or your grandfather set out the tree any number of years ago.
