It is interesting, too, to see that as far as we can tell at present, in the case of fossil-fish and other living creatures, the lowest forms are found _first_ (that is, _farthest back_), and are followed by remains of creatures higher in the scale of life; that is to say, not so simple in structure. In using the words "higher" or "lower," we do not mean that there is anything imperfect about the humbler creatures; they are exactly suited to the life which has been given to them to live, but their form is very simple compared with that of "higher" animals, just as a three-legged stool is much more simple in its construction, and is made of fewer parts, than a watch. I may tell you a little about these lowly creatures when we speak of the FIFTH DAY of Creation, and then you will see that they were all made according to a "perfect goodly pattern" or plan, and each "after its kind"; for if we read the pages of the Stone Book aright, we shall see plainly written there that from the first beginnings of life, as far as it is given us to trace them, the goodness and wisdom and power of God are shown in the way in which the smallest creature of His hand is suited to the place appointed to it to fill, by Him who is "good to all," and whose "tender mercies are over all His works." But there is a great difference between what we may thus glean from the study of the earth, and what is revealed to us by the clear teaching of the Word of God, as He tells us what He did in His wonderful work of Creation, and how He "saw everything that He had made, and behold it was very good." When God speaks, all is clear and simple and true; and is to be understood by believing His word: when we come to the thoughts of men about what happened in the far past, especially when they try to settle not only the _when_ but the _how_ of His mighty working, much is dark uncertainty. Should we then _not_ study the letters of the Stone Book? I did not say so; "God has made everything beautiful in its time," and His handiwork in the past as well as the present is indeed worthy of our attention. But in reading books about geology, more perhaps than in any other study, you need to ask God to teach you to hold fast by His Word. Then, if you read that many geologists now believe that there has been no special creation of fish or bird or beast of the earth, but that "all the many forms of plant and animal life have been unfolded out of a few simple forms, just as the stem, the leaf, and the flower are evolved out of a simple seed"--you will say at once, "That cannot be; for God has plainly told us of both plants and animals that they were made each 'after its kind,' and therefore there can never have been such a thing as a fish developing into a bird, or a bird into a lizard: nor, so far as I have seen, is any such creature to be found in a fossil state."
