While in the White House I always tried to get a couple of hours' exercise in the afternoons--sometimes tennis, more often riding, or else a rough cross-country walk, perhaps down Rock Creek, which was then as wild as a stream in the White Mountains, or on the Virginia side along the Potomac. My companions at tennis or on these rides and walks we gradually grew to style the Tennis Cabinet; and then we extended the term to take in many of my old-time Western friends such as Ben Daniels, Seth Bullock, Luther Kelly, and others who had taken part with me in more serious outdoor adventures than walking and riding for pleasure. Most of the men who were oftenest with me on these trips--men like Major-General Leonard Wood; or Major-General Thomas Henry Barry; or Presley Marion Rixey, Surgeon-General of the Navy; or Robert Bacon, who was afterwards Secretary of State; or James Garfield, who was Secretary of the Interior; or Gifford Pinchot, who was chief of the Forest Service--were better men physically than I was; but I could ride and walk well enough for us all thoroughly to enjoy it. Often, especially in the winters and early springs, we would arrange for a point to point walk, not turning aside for anything--for instance, swimming Rock Creek or even the Potomac if it came in our way. Of course under such circumstances we had to arrange that our return to Washington should be when it was dark, so that our appearance might scandalize no one. On several occasions we thus swam Rock Creek in the early spring when the ice was floating thick upon it. If we swam the Potomac, we usually took off our clothes. I remember one such occasion when the French Ambassador, Jusserand, who was a member of the Tennis Cabinet, was along, and, just as we were about to get in to swim, somebody said, "Mr. Ambassador, Mr. Ambassador, you haven't taken off your gloves," to which he promptly responded, "I think I will leave them on; we might meet ladies!" We liked Rock Creek for these walks because we could do so much scrambling and climbing along the cliffs; there was almost as much climbing when we walked down the Potomac to Washington from the Virginia end of the Chain Bridge. I would occasionally take some big-game friend from abroad, Selous or St. George Littledale or Captain Radclyffe or Paul Niedicke, on these walks. Once I invited an entire class of officers who were attending lectures at the War College to come on one of these walks; I chose a route which gave us the hardest climbing along the rocks and the deepest crossings of the creek; and my army friends enjoyed it hugely--being the right sort, to a man.
