Whatever influence animated me, I found cause to congratulate myself on having obeyed it as soon as I prepared to seal the letter in my own room. I had originally closed the envelope in the usual way by moistening the adhesive point and pressing it on the paper beneath, and when I now tried it with my finger, after a lapse of full three-quarters of an hour, the envelope opened on the instant, without sticking or tearing. Perhaps I had fastened it insufficiently? Perhaps there might have been some defect in the adhesive gum?
Or, perhaps—No! it is quite revolting enough to feel that third conjecture stirring in my mind. I would rather not see it confronting me in plain black and white.
