earthquake, says a great poet, when speaking of the general tendency in all dangers to come round by successive and reiterated shocks-- 'The earthquake is not satisfied at once.' All dangers which lie deeply seated are recurrent dangers; they intermit, only as the revolving lamps of a light-house are periodically eclipsed. The General Assembly of 1843, when closing her gates upon the Seceders, shut _in_, perhaps, more of the infected than at the time she succeeded in shutting _out_. As respected the opinion of the world outside, it seemed advisable to shut out the least number possible; for in proportion to the number of the Seceders, was the danger that they should carry with them an authentic impression in their favor. On the other hand, as respected a greater danger, (the danger from internal contagion), it seemed advisable that the church should have shut out (if she could) very many of those who, for the present, adhered to her. The broader the separation, and the more absolute, between the church and the secession, so much the less anxiety there would have survived lest the rent should spread. That the anxiety in this respect is not visionary, the reader may satisfy himself by looking over a remarkable pamphlet, which professes by its title to separate the _wheat from the chaff_. By the 'wheat,' in the view of this writer, is meant the aggregate of those who persevered in their recusant policy up to the practical result of secession. All who stopped short of that consummation (on whatever plea), are the 'chaff.' The writer is something of an incendiary, or something of a fanatic; but he is consistent with regard to his own principles, and so elaborately careful in his details as to extort admiration of his energy and of his patience in research.
