"Yes," he replied; "but they are not ten years old, and every year changes them."

By this time we were gliding through the gardens of Brookline and Brighton, which have been afflicted of late years with the Mansard epidemic. It has swept the whole region. Scarcely a house has escaped. Even the newest are touched,—sometimes only upon the extremities or outbuildings, but more frequently they are covered all over with the Mansard.

"That affection of the house-top," whispered I to my friend, "was originally derived from the dome of the Invalides, and has raged now for a century and a half."

"Yes," replied my companion, gravely, "we are not very fastidious in our importations."

He went on murmuring to himself as usual. Then he resumed more audibly,—

"I suppose that most people, upon looking at me, would take me for a foreigner. But you know how peculiarly native American I am. I am indeed only a watch, and," added my modest friend, glancing at the gold chain which hung from my waistcoat button-hole to the pocket, "if you will pardon my melancholy joke, I am for putting Americans only upon guard."

This military expression suddenly sent my thoughts elsewhere; and for some time the rattling of the cars sounded in my ears like another rattling, and the gentle Charles River was to my eyes the historic Rapidan or Rappahannock.

"Don't you think," unobtrusively ticked my watch, "that the exhortation to encourage home-industry has a peculiar force just now? I mean nothing personal; and I hope you will not think me too forward or fast."

"I have never had reason to think so," I answered; "and I am so used to look upon your candid face to know exactly what the hour is, that I shall be very much obliged, if you will tell me the time of day in this matter also; unless, indeed, you should find the jar of the cars too much for you, and prefer to stop before you talk."

"If I stopped, I certainly could not talk," my watch answered; "and did you ever know me to stop on account of any jar?"
