The State Board of Horse Commissioners, during the season of 1916, was able to cover the State more thoroughly than has ever been possible before. Because of this greater activity and more complete canvass the number of licensed stallions and jacks in this report is greater than before. During the season of 1916 there were in force 420 licenses a against 289 for 1915.
