There was something so absurd in the association of Madame Fontaine\'s charms with the extinction of Mr. Engelman\'s pipe, that I burst out laughing. My good old friend looked at me in grave surprise.

"What is there to laugh at in my forgetting to keep my pipe alight?" he asked. "My whole mind, David, was absorbed in that magnificent woman the instant I set eyes on her. The image of her is before me at this moment—an image of an angel in moonlight. Am I speaking poetically for the first time in my life? I shouldn\'t wonder. I really don\'t know what is the matter with me. You are a young man, and perhaps you can tell. Have I fallen in love, as the saying is?" He took me confidentially by the arm, before I could answer this formidable question. "Don\'t tell friend Keller!" he said, with a sudden outburst of alarm. "Keller is an excellent man, but he has no mercy on sinners. I say, David! couldn\'t you introduce me to her?"

Still haunted by the fear that I had spoken too unreservedly during my interview with the widow, I was in the right humor to exhibit extraordinary prudence in my intercourse with Mr. Engelman.

"I couldn\'t venture to introduce you," I said; "the lady is living here in the strictest retirement."

"At any rate, you can tell me her name," pleaded Mr. Engelman. "I dare say you have mentioned it to Keller?"

"I have done nothing of the sort. I have reasons for saying nothing about the lady to Mr. Keller."

"Well, you can trust me to keep the secret, David. Come! I only want to send her some flowers from my garden. She can\'t object to that. Tell me where I am to send my nosegay, there\'s a dear fellow."

I dare say I did wrong—indeed, judging by later events, I know I did wrong. But I could not view the affair seriously enough to hold out against Mr. Engelman in the matter of the nosegay. He started when I mentioned the widow\'s name.

"Not the mother of the girl whom Fritz wants to marry?" he exclaimed.

"Yes, the same. Don\'t you admire Fritz\'s taste? Isn\'t Miss Minna a charming girl?"

"I can\'t say, David. I was bewitched—I had no eyes for anybody but her mother. Do you think Madame Fontaine noticed me?"

"Oh, yes. I saw her look at you."

"Turn this way, David. The effect of the moonlight on you seems to make you look younger. Has it the same effect on me? How old should you guess me to be to-night? Fifty or sixty?"

"Somewhere between the two, sir."

(He was close on seventy. But who could have been cruel enough to say so, at that moment?)

My answer proved to be so encouraging to the old gentleman that he ventured on the subject of Madame Fontaine\'s late husband. "Was she very fond of him, David? What sort of man was he?"

I informed him that I had never even seen Dr. Fontaine; and then, by way of changing the topic, inquired if I was too late for the regular supper-hour at Main Street.

"My dear boy, the table was cleared half an hour ago. But I persuaded our sour-tempered old housekeeper to keep something hot for you. You won\'t find Keller very amiable to-night, David. He was upset, to begin with, by writing that remonstrance to your aunt—and then your absence annoyed him. \'This is treating our house like an hotel; I won\'t allow anybody to take such liberties with us.\' Yes! that was really what he said of you. He was so cross, poor fellow, that I left him, and went out for a stroll on the bridge. And met my fate," added poor Mr. Engelman, in the saddest tones I had ever heard fall from his lips.

My reception at the house was a little chilly.

"I have written my mind plainly to your aunt," said Mr. Keller; "you will probably be recalled to London by return of post. In the meantime, on the next occasion when you spend the evening out, be so obliging as to leave word to that effect with one of the servants." The crabbed old housekeeper (known in the domestic circle as Mother Barbara) had her fling at me next. She set down the dish which she had kept hot for me, with a bang that tried the resisting capacity of the porcelain severely. "I\'ve done it this once," she said. "Next time you\'re late, you and the dog can sup together."

The next day, I wrote to my aunt, and also to Fritz, knowing how anxious he must be to hear from me.

To tell him the whole truth would probably have been to bring him to Frankfort as fast as sailing-vessels and horses could carry him. All I could venture to say was, that I had found the lost trace of Minna and her mother, and that I had every reason to believe there was no cause to feel any present anxiety about them. I added that I might be in a position to forward a letter secretly, if it would comfort him to write to his sweetheart.

In making this offer, I was, no doubt, encouraging my friend to disobey the plain commands which his father had laid on him.

But, as the case stood, I had really no other alternative. With Fritz\'s temperament, it would have been simply impossible to induce him to remain in London, unless his patience was sustained in my absence by a practical concession of some kind. In the interests of peace, then—and I must own in the interests of the pretty and interesting Minna as well—I consented to become a medium for correspondence, on the purely Jesuitical principle that the end justified the means. I had promised to let Minna know of it when I wrote to Fritz. My time being entirely at my own disposal, until the vexed question of the employment of women was settled between Mr. Keller and my aunt, I went to the widow\'s lodgings, after putting my letters in the post.

Having made Minna happy in the anticipation of hearing from Fritz, I had leisure to notice an old china punch-bowl on the table, filled to overflowing with magnificent flowers. To anyone who knew Mr. Engelman as well as I did, the punch-bowl suggested serious considerations. He, who forbade the plucking of a single flower on ordinary occasions, must, with his own hands, have seriously damaged the appearance of his beautiful garden.

"What splendid flowers!" I said, feeling my way cautiously. "Mr. Engelman himself might be envious of such a nosegay as that."

The widow\'s heavy eyelids drooped lower for a moment, in unconcealed contempt for my simplicity.

"Do you really think you can mystify me?" she asked ironically. "Mr. Engelman has done more than send the flowers—he has written me a too-flattering note. And I," she said, glancing carelessly at the mantelpiece, on which a letter was placed, "have written the necessary acknowledgment. It would be absurd to stand on ceremony with the harmless old gentleman who met us on the bridge. How fat he is! and what a wonderful pipe he carries&mda............
