When Johnnie Green turned Twinkleheels and the old horse Ebenezer into the pasture, the first thing they did was to drop down on the grass and enjoy a good roll. There was a vast difference in their actions. Twinkleheels was as spry as a squirrel. He rolled from one side to the other and back again, jumped up and shook himself like old dog Spot, almost before Ebenezer had picked out a nice, smooth place to roll on.
