Lilliesleaf Kirkyard, Scottish Borders

Possibly, from right to left - preacher in the centre with hand resting on the bible, a skeleton ('King of Terrors' depicting death) holding onto the preacher's stick. The skeleton in turn is holding an hourglass indicating the passing of time ('well known to all who watched it during the long sermons' - Betty Willsher). I wonder if the headstone carver was indicating the preacher's sermons were too long?!
