When we examine this interesting spot a little more minutely, we detect many other granite veins, each affording some curious and minute fact in harmony with the preceding remarks. Every one knows that it is easier to split a piece of wood in the direction of the grain, than transversely to that direction. In the same way we may infer that it is easier for a liquid granite to insinuate itself _between_ the strata than to force its way _across_ them, and on examination we find this to have been the case. In the first place, the large vein first mentioned running in the course of the strata is broader than all the transverse veins put together. Secondly, when we examine the cross veins, we find they have had more difficulty in forcing their way: hence they frequently contain fragments. Perhaps, however, an examination at another point near the entrance of the abandoned lead-mine affords the most curious evidence of these remarks, for there we perceive that the vein does not hold a straight course, nor is it of equal thickness throughout, but, on the contrary, is of unequal breadth, and serpentine, as if the strata had been violently lacerated instead of being split. In this case the vein has cut across the strata, and includes fragments of the mica-schist. But the most curious circumstance in this example is, that the vein itself has been broken, and its fractured extremities a little displaced and detached, thus proving that the strata had been exposed to concussion and displacement at a period posterior to that when the vein was formed. If this very brief description will induce any of our readers to visit the granite veins of Killiney, we are sure he will find that his excursion will not be an unimproving one, and he will perhaps be convinced that he has only to look about him to find sources of enjoyment which so many are ignorant of, but which are within the command of all. S. * * * * * DOMESTIC DISCIPLINE OF THE DUTCH.--There are two things of a peculiar character in Holland, which deserve to be noticed. One is the enactment authorising husbands, wives, and children to be imprisoned in a house of correction set apart for the chastisement of offences against the laws by which the relations of social life are governed--the other, a contrivance for compelling the incorrigibly idle to work. In one of the rooms is a pump, and a stream of water runs in from the ceiling; so that unless the prisoner labours continually, he must be inevitably drowned. * * * * *
