Many hunters believe that could he be closely observed and studied throughout the world, were the logs for one voyage of the entire whale fleet carefully colated. On this hint attempts have been made to construct elaborate migratory charts of the sperm whale. The chart divides the oceans into districts of five degrees of latitude by five degrees of longitude. Through each of which districts are 12 columns for the 12 months and horizontally through each district are three lines.
