"For this reason. I think that any sudden emotion--violent grief, for instance--any unexpected and crushing blow--might at once disturb the balance of his mind. Let his life run on in an even groove, and all will be well with him." My companion was silent for a few moments. "Did you mention your friend's name?" he asked. I laughed. "Doctors never give names when they quote cases." At the next station my companion left the train. He bade me a polite adieu, and thanked me for the pleasure my conversation had given him. After wondering what station in life he occupied I dismissed him from my mind, as one who had crossed my path for a short time and would probably never cross it again. Although I did not see Charles Carriston I received several letters from him during the course of the year. He had not forgotten our undertaking to pass my next holiday together. Early in the autumn, just as I was beginning to long with a passionate longing for open air and blue skies, a letter came from Carriston. He was now, he said, roughing it in the Western Highlands. He reminded me of last year's promise. Could I get away from work now? Would I join him? If I did not care to visit Scotland, would I suggest some other place where he could join me? Still, the scenery by which he was now surrounded was superb, and the accommodation he had secured, if not luxurious, fairly comfortable. He thought we could not do better. A postscript to his letter asked me to address him as Cecil Carr, not Charles Carriston. He had a reason for changing his name; a foolish reason I should no doubt call it. When we met he would let me know it. This letter at once decided me to accept his invitation. In a week's time my arrangements for leave of absence were complete, and I was speeding northward in the highest spirits, and well equipped with everything necessary for my favorite holiday pursuit. I looked forward with the greatest pleasure to again meeting Carriston. I found him at Callendar waiting for me. The coach did not follow the route we were obliged to take in order to reach the somewhat unfrequented part of the country in which our tent was pitched, so my friend had secured the services of a primitive vehicle and a strong shaggy pony to bear us the remainder of the journey. So soon as our first hearty greetings were over I proceeded to ascertain how the last year had treated Carriston. I was both delighted and astonished at the great change for the better which had taken place in his manner, no less than his appearance. He looked far more robust; he seemed happier, brighter; although more like ordinary humanity. Not only had he greeted me with almost boisterous glee, but during our drive through the wonderful scenery he was in the gayest of spirits and full of fun and anecdote. I congratulated him heartily upon the marked improvement in his health, both mentally and physically.
