THE SNOWFLAKE. "Now, if I fall, will it be lot my To be cast in some lone and lowly spot, And there will my course be ended?" "Oh, no!" said the Earth," thou shalt not lie "And then thou shalt have thy choice to be In the cup where the bee and the fire-fly feed, Regaining thy dazzling brightness. "I'll let thee awake from thy transient sleep, In a drop from the unlock'd fountain; "Or, wouldst thou return to a home in the skies, To shine in the Iris I'll let thee arise, And appear in the many and glorious dyes A pencil of sunbeams is blending! But true, fair thing, as my name is Earth, “Then I will drop," said the trusting Flake: "And if true to thy word and just thou art, For I would be placed in the beautiful bow, MISS H. GOULD. POWERSCOURT WATERFALL. THE Water-Fall of Powerscourt is formed by the Dargle; it is situate in the county of Wicklow; and, when the river is full, presents a grand appearance. "The stream," says Miss Zornlin, "precipitates itself over a nearly perpendicular cliff, three hundred feet in height, and falls into a natural basin or reservoir, encircled by rocky masses of considerable magnitude, whilst the whole scene is backed by mountains. This fall exhibits rather a singular phenomenon, in the different degrees of velocity with which the water descends in different parts of the cascade. Thus, on one side, the water may be observed to pour down with considerable velocity, whilst, on the other side, the fall in the upper part presents the appearance of a continued stream of frothy foam, gliding slowly down the face of the cliff, though the lower part moves with greater velocity. This circumstance is, however, readily accounted for, being, in fact, mainly attributable to the comparatively small body of water which forms the cascade. The water on the one side-that which descends with the greater velocity, and this forms by far the largest portion of the cascade-meets with no interruption in its descent, but falls almost from the very top to the bottom, in one unbroken sheet. On the other side, however, the cliff in the other part deviates from the perpendicular; and, the consequence is, that, owing to the slope or inclination of the rock over which it flows, the progress of the water is checked in that particular part: though lower down-where the cliff is again perpendicular-it regains its velocity. If the body of water in this cascade were greater, this phenomenon would not occur: for, in that case, not only would the whole body rush down with great velocity, but the depth, or volume of the stream, would overcome these inequalities, and a uniform surface thus be presented. A beautiful rainbow is occasionally displayed on the spray of this water-fall. It is, however, only visible on summer mornings, between five and six o'clock. The prismatic colours are said to be vividly exhibited." |
