At the time I made the trip to Yellowstone Park with President Roosevelt in the spring of 1903, I promised some friends to write up my impressions of the President and of the Park, but I have been slow in getting around to it. The President himself, having the absolute leisure and peace of the White House, wrote his account of the trip nearly two years ago! But with the stress and strain of my life at "Slabsides,"-administering the affairs of so many of the wild creatures of the woods about me,-I have not till this blessed season found the time to put on record an account of the most interesting thing I saw in that wonderful land, which, of course, was the President himself.
