The first note that our witness enters in his 'log' relates to his impressions of the causes of the catastrophe, which was not effected supernaturally, but by natural causes. These are the 'breaking up of the fountains of the great deep' and the 'opening of the windows of heaven.' These expressions must be interpreted in accordance with the use of similar terms in the account of creation in Genesis i., the more so that this statement is a portion regarded by the composite theory as Elohistic. On this principle of interpretation, the great deep is that universal ocean which prevailed before the elevation of the dry land, and the breaking up of its fountains is the removal of that restriction placed upon it when its waters were gathered together into one place. In other words, the meaning is the invasion of the land by the ocean. In like manner, the windows of heaven, the cloudy reservoirs of the atmospheric expanse, or possibly waterspouts, or even volcanic eruptions, and not necessarily identical with the great rain extending for forty days, as stated in the following clause. The Chaldean record adds the phenomena of thunder and tempest, but omits the great deep; an indication that it is an independent account, and by a less informed or less intelligent narrator. It is worthy of note that our narrator has no idea of any river inundation in the case.

At this stage we are brought into the presence of the question: Is the Deluge represented as a miraculous or a merely natural phenomenon? Yet, from a scientific point of view, this question has not the significance usually attributed to it. True miracles are not, and cannot be, contraventions or violations of God's natural laws. They are merely unusual operations of natural powers under their proper laws, but employed by the Almighty for effecting spiritual ends. Thus, naturally, they are under the laws of the material world, but, spiritually, they belong to a higher sphere. In the present case, according to the narrative in Genesis, the Flood was physically as much a natural phenomenon as the earthquakes at Ischia, or the eruption of Krakatoa. It was a miraculous or spiritual intervention only in so far as it was related to the destruction of an ungodly race, and as it was announced beforehand by a prophet. Had the approaching eruption of Krakatoa been intended as a judgment on the wicked, and had it been revealed to anyone who had taken pains to warn his countrymen and then to provide for his own safety, this would have given to that eruption as much of a miraculous character as the Bible attaches to the Deluge. In the New Testament, where we have more definite information as to miracles, they are usually called 'powers' and 'signs,' less prominence being given to the mere wonder which is implied in the term 'miracle.' Under the aspect of powers, they imply that the Creator can do many things beyond our power and comprehension, just as in a lesser way a civilised man, from his greater knowledge of natural laws and command over natural energies, can do much that is incomprehensible to a savage; and in this direction science teaches us that, given an omnipotent God, the field of miracle is infinite. As signs, on the other hand, such displays of power connect themselves with the moral and spiritual world, and become teachers of higher truths and proofs of Divine interference. The true position of miracles as signs is remarkably brought out in that argument of Christ, in which He says, 'If ye believe not My words, believe Me for the works' sake.' It is as if a civilised visitor to some barbarous land, who had been describing to an incredulous audience the wonders of his own country, were to exhibit to them a watch or a microscope, and then to appeal to them that these were things just as mysterious and incredible as those of which he had been speaking.

Returning to the Deluge, we may observe that such an invasion of the great deep is paralleled by many of which geology presents to us the evidence, and that our knowledge of nature enables us to conceive of the possibility of greater miracles of physical change than any on record, such as, for instance, the explosion of the earth itself into an infinity of particles, the final extinction of the solar heat, or the accession to this heat of such additional fierceness as to burn up the attendant planets. All this might take place without any interference with God's laws, but merely by correlations and adjustments of them, as much within His power as the turning on or stopping of a machine is in the power of a human engineer. Further, such acts of Divine power may be related to moral and spiritual things, just as easily as any outward action resulting from our own will may be determined by moral considerations. The time is past when any rational objection can be made on the part of science to the so-called miracles of the Bible.

To return to the passengers in the ark. This must have been built on high ground, or the progress of the Deluge must have been slow, for forty days elapsed before the waters reached the ship and floated it. It is not unlikely that the ark was built on rising ground, for here supplies of timber would be nearer. It has puzzled some simple antiquarians to find dug-out canoes of prehistoric date on the tops of hills; but they did not reflect that the maker of a canoe would construct his vessel where the suitable wood could be found, since it would be much easier to carry the finished canoe to the shore than to drag thither the solid log out of which it was to be fashioned. So Noah would naturally build his ark where the wood he required could be procured most easily. The Chaldean narrator seems to have overlooked this simple consideration, for he mentions a launching and trial-trip of the ship, a sure mark that he is a later authority than the writer in Genesis.

The inmates of the ark now felt that it was moving on the waters, a new and dread sensation which must have deeply impressed their minds, and they soon became aware that the ark not merely floated, but 'went,' or made progress in some definite direction. Remark the simple yet significant notes—'The ark was lift up from the earth,' and 'the ark went upon the face of the waters.' The direction of driftage is not stated, but it is a fair inference, from the probable place of departure in Chaldea and that of final grounding of the ark, that it was northward or inland, which would indicate that the chief supply of water was from the Indian Ocean, and that it was flowing inward toward the great sunken plain of interior Asia, which, however, the ark did not reach, but grounded in the hilly region known to the Hebrews as Ararat, to the Chaldeans as Nisr. A curious statement is made here (Elohist) as to the depth of the water being fifteen cubits. Even in a flat country so small a depth would not cover the rising grounds; but this is obviously not the meaning of the narrator, but something much more sensible and practical. It is not unlikely that the measure stated was the water-draught of the loaded ark, and that as the voyagers felt it rise and fall on the waves, they may have experienced some anxiety lest it should strike and go to pieces. It was no small part of the providential arrangement in their case that in the track of the ark everything was submerged more than fifteen cubits before they reached it. Hence this note, which is at the same time one of the criteria of the simple veracity of the history. The only other remark in this part of the narrative relates to the entire submergence of the whole country within sight, and the consequent destruction of animal life; and here the enumeration covers all land animals, and the terms used are thus more general than those applied to the animals preserved in the ark. The Deluge culminated, in so far as our narrator observed, in one hundred and fifty days.

His next experience is of a gale of wind, accompanied or followed by cessation of the rain and of the inflow of the oceanic waters. [50] The waters then decreased, not regularly, but by an intermittent process, 'going and returning'; but whether this was a tidal phenomenon or of the nature of earthquake waves we have no information. At length the ark grounded, apparently on high ground or in thick weather, for no land was visible; but at length, after two months, neighbouring hill-tops were seen.

[50] Genesis viii. 1, 2: 'And Elohim made a wind to pass over the earth, and the waters abated,' &c.

The incident of sending out birds to test the recession of the waters deserves notice, because of its apparently trivial nature, because it appears with variations in the Chaldean account, and because it has been treated in a remarkably unscientific manner by some critics. It indicates the uncertainty which would arise in the mind of the patriarch because of the fluctuating decrease of the waters, and possibly also a misty condition of the air preventing a distinct view of distant objects. The birds selected for the purpose were singularly appropriate. The raven is by habit a wanderer, and remarkable for power of flight and clearness of distant vision. So long, therefore, as it made the ark its headquarters, 'going and returning' [51] from its search for food, it might be inferred that no habitable land was accessible. The dove, sent out immediately after the raven, [52] is of a different habit. It could not act as a scavenger of the waters and go and return, but could leave only if it found land covered with vegetation. As a domesticated bird also, it would naturally come back to be taken into the ark. Hence it was sent forth at intervals of seven days, returning with an olive leaf when it found tree tops above the water, and remaining away when it found food and shelter. The Chaldean account adds a third bird, the swallow—a perfectly useless addition, since this bird, if taken into the ark at all, would from its habits of life be incapable of affording any information. This addition is a mark of interpolation in the Chaldean version, and proceeded perhaps from the sacred character attached by popular superstition to the swallow, or from the familiar habits of the bird suggesting to some later editor its appropriateness. Singularly enough, the usually judicious Schrader, probably from deficient knowledge of the habits of birds, fails to appreciate all this, and after a long discussion prefers the Babylonian legend for reasons of a most unscientific character, actually condemning the perfectly natural and clear Biblical story as artificial and due to a recent emendation. He says: 'When the story passed over to the Hebrews, the name of the swallow has disappeared,' and 'it is only from the Babylonian narrative that the selection of the different birds becomes clear.' This little disquisition of Schrader is, indeed, one of the most amusing instances of that inversion of sound criticism which results when unscientific commentators tamper with the plain statements of truthful and observant witnesses.
