people to see it. I should not have noticed it had I not been about at all hours with my gun as a boy. It is much more visible by moonlight, when the rabbits' white tails go dot, dot, lightly over the grass, and you are just as likely to shoot at their shadows as at their bodies. As the scythe of the mower mows a swathe before him, so the semicircle of light moves in front over the dew, and the grass appears another tint, as it does after a roller has passed.
In a scientific publication not long since, a letter was published describing what the writer supposed was indeed something extraordinary. He had seen a fragment of rainbow—a square piece, as it were—by itself in the sky, some distance to one side of the sun. In provincial papers such letters may often be found, and even, until lately, in papers issued in London; now with accurate accounts of an ordinary halo about the sun, now with a description of a prismatic cloud round the moon, and one day some one discovered that there were two currents of air, as the clouds went in two directions. Now, it is clear enough that none of these writers had ever been out with a gun or a rod; I mean out all day, and out in the full sense of the phrase. They had read books of science; from their language they were thoroughly educated, and felt a deep interest in natural phenomena. Yet what a marvel was here made out of the commonest incidents of the sky! Halos about the sun happen continually; the prismatic band or cloud about the moon is common; so is the detached rainbow; as for the two currents of air, the clouds often travel in three directions, occasionally in four. These incidents are no more surprising to a sportsman
