The existence of our nation evidently depends far more upon the fundamental and essential, nay obvious, old and common human virtues of very common people than upon our art and learning, the shrewdness of our politicians and profiteers, the amount of our wealth and exports, our inventions or luxuries, the winning of an election, or the defeat of any party. In one word, which we have already repeated _ad nauseam_, our chief business to-day is to continue the line of development clearly marked out by our benighted ancestors of prehistoric days--to exercise, develop, and strengthen the best instincts and feelings crystallized out of millennia of experience; to see to it that they are expressed in the law and practices of the land and commonwealth; and that they are not smothered under a mass of inventions of yesterday and of conventions of to-day. The fact that all this is entirely obvious should not conceal its importance. The old message comes to us: "If thou altogether holdest thy peace at this time, then shall there enlargement and deliverance arise from another place; but thou and thy father's house shall be destroyed; and who knoweth whether thou art come to the kingdom for such a time as this?" In the northern ocean we see icebergs moving slowly southward. They are not driven by the winds which to-day are blowing against their broad fronts. The most conspicuous feature of our field of vision is the white foam capping the waves. To-morrow it will be blown away, evaporate, and disappear in the shifting winds which have tossed it into view. The berg is carried by the great polar current, silent, inconspicuous, irresistible, unchanging in its course, guided by still deeper and more ancient and permanent cosmic forces. We know something about oceanic currents. Of the current of the evolution of life we know almost nothing; but hope that our theories are no more inadequate than the feelings of our Neolithic ancestors. Certainly the current has not yet been charted. We catch glimpses of the direction of its sweep. Over what stormy and dangerous seas and to what undiscovered island or continent it is carrying us we do not know. It seems to set toward fairer climes beyond our vision. We set sail millions of years ago; we shall not arrive to-morrow. BIBLIOGRAPHY A FEW SUGGESTIONS The first series of books referred to in the following lists (A-O) are general, and every one covers a large field. The works of Déchelette and Hoernes (A and B) contain a very rich bibliography down to 1907 or 1908. They should be carefully studied first of all; afterward the remainder of the list. I have omitted from the following list many excellent articles to which they refer. This list will satisfy the needs of the ordinary reader.
