Geology is rapidly taking its place as an introduction to the higher history of man. If the author has sought to exalt a favorite science, it has been with the desire that man-in whom geological history had its consummation, the prophecies of the successive ages their fulfilment-might better comprehend his own nobility and the true purpose of his existence.

Science, while it penetrates deeply the system of things about us, sees everywhere, in the dim limits of vision, the word mystery.

There can be no real conflict between the two Books of the Great Author. Both are revelations made by Him to man,-the earlier telling of God-made harmonies coming up from the deep past, and rising to their height when man appeared, the later teaching man's relations to his Maker, and speaking of loftier harmonies in the eternal future.

A map of the moon... should be in every geological lecture room; for no where can we have a more complete or more magnificent illustration of volcanic operations. Our sublimest volcanoes would rank among the smaller lunar eminences; and our Etnas are but spitting furnaces.

Mr Hall's hypothesis has its cause for subsidence, but none for the lifting of the thickened sunken crust into mountains. It is a theory for the origin of mountains, with the origin of mountains left out.

For nine miles along a submerged ridge, the corals rise in lumpy hillocks that spread out 100 yards or more, resembling heaped scoops of rainbow sherbet and Neapolitan ice cream. The mounds, some 100 feet tall, sprout delicate treelike gorgonians that sift currents for a plankton meal. Fish, worms and other creatures dart or crawl in every crevice. This description could apply to thousands of coral reefs in shallow, sun-streaked tropical waters from Australia to the Bahamas. But this is the Sula Ridge, 1,000 feet down in frigid darkness on the continental shelf 100 miles off Norway's coast.

Some writers, rejecting the idea which science had reached, that reefs of rocks could be due in any way to "animalcules," have talked of electrical forces, the first and last appeal of ignorance.
