Mrs. Treherne had large estates in Cornwall, on which, since her husband's death, she had almost constantly resided; and thither, with Madelon, she proceeded, a few days after their arrival in London. Graham did not go with them. He had been appointed to accompany a government exploring party into Central America, and his time was fully occupied with business to settle, arrangements to make, outfit to purchase, and, moreover, with running down to his sister's house in the country as often as possible, so as to devote every spare hour to Miss Leslie. The summer love-making had ended in an engagement before he started for Spa--an engagement which-- neither he nor Miss Leslie having any money to speak of-- promised to be of quite indefinite length. In the midst of all his bustle, however, Graham contrived to take Madelon to as many sights as could be crowded into the three or four days that they stayed at the London hotel; and in a thousand kind ways tried to encourage and cheer the child, who never said a word about her grief, but drooped more and more as the moment for separation drew near. Graham went to see her and his aunt off at the Great Western terminus, and it was amidst all the noise, and hurry, and confusion of a railway-station that they parted at last. It was all over in a minute, and as Graham stood on the platform, watching the train move slowly out of the station, a little white face appeared at a carriage- window, two brown eyes gazed wistfully after him, a little hand waved one more farewell. It was his last glimpse of our small Madelon. PART III. CHAPTER I. Letters.
