And then he drew a dial from his poke, And, looking on it with lack-lustre eye, Says, very wisely, “It is ten o’clock.” This is a ring of brass, much like a miniature dog-collar, and has, moving in a groove in its circumference, a narrower ring with a boss, pierced by a small hole to admit a ray of light. The latter ring is made movable, to allow for the varying declination of the sun in the several months of the year, and the initials of these are marked in the ascending and descending scale on the larger ring, which bears also the motto: Set me right, and use me well, And I y^e time to you will tell. The hours are lined and numbered on the opposite concavity. When the boss of the sliding ring is set, and the ring is suspended by the ring directly towards the sun, a ray of light passing through the hole in the boss impinges on the concave surface, and the hour is told with fair accuracy. Mr. Thomas Q. Couch, of Bodmin, thus describes this Dial in _Notes and Queries_, 3d series, No. 36. Mr. Charles Knight, in his _Pictorial Shakspeare_, has engraved a dial of this kind, as an illustration of _As you like it_. Mr. Redmond, of Liverpool, describes the old pocket ring-dial as common in the county of Wexford some twenty-five years ago: there was hardly a farm-house where one could not be had. The same Correspondent of _Notes and Queries_, 3d series, No. 39, describes a door-sill marked with the hour for every day in the year: the sill had a full southern aspect, so that when the sun shone, the time could be read as correctly as by any watch. Another Correspondent of _Notes and Queries_, 2d series, No. 38, has an ingenious pocket-dial, sold by one T. Clarke: it is merely a card, with a small plummet hanging by a thread, and a gnomon, which lies flat on the card, but, when lifted up, casts the shadow to indicate the hour of the day, and also the hours of sunrise and sunset. In the United Service Museum, Whitehall, is a Sun-dial, with a burning-glass arranged to fire a small gun at noon; also a large Universal Dial, with a circle showing minutes; and another large Universal Dial, with horizontal plate and spirit-level. Suppose we collect a few of the monitory inscriptions on dials in various places. Hazlitt, in a graceful paper “On a Sun-dial,” tells us that Horas non numero nisi serenas is the motto of a Sun-dial near Venice; and the same line is painted in huge letters over the Sun-dial in front of an old farmhouse near Farnworth, in Lancashire. At Hebden Bridge, in Yorkshire, is this quaint motto: Quod petis, umbra est. Canon Bowles, in his love of the solemn subject, prescribed the following, with paraphrastic translations: _Morning Sun._—Tempus volat. Oh! early passenger, look up—be wise, And think how, night and day, _time onward flies_.
