AT Kharkov, on my return journey, I recovered half of my lost luggage; the other half, a box full of books and papers, had not turned up: neither by bribes nor by words could it be found. We spent a whole day searching the Customs House, but failed to find any trace of it. I learned afterwards that it had been left behind at Ostend, through the negligence of a porter there. The loss of this box was a matter of sorrow. All through the winter I felt the loss of it. It was only in April, after immense correspondence, that I recovered it, and then it was no use since I had made up my mind to spend the summer on the mountains.
