made with a seam round the wrist are survivals from real cuffs when the sleeve used to be turned back. Thus it is seen that the present ceremonial dress-coat owes its peculiarities to being descended from the old-fashioned practical coat in which a man rode and worked. Or again, if one looks in modern English life for proof of the Norman Conquest eight centuries ago, one may find it in the " Oh yes! Oh yes !" of the town-crier, who all unknowingly keeps up the old French form of proclamation, "Oyez! Oyez !" that is, "Hear ye! Hear ye!" To what yet more distant periods of civilization such survivals may reach back, is well seen in an example from India. There, though people have for ages kindled fire for practical use with the flint and steel, yet the Brahmans, to make the sacred fire for the daily sacrifice, still use the barbaric art cf violently boring a pointed stick into another piece of wood till a spark comes. Asked why they thus waste their labour when they know better, they answer that they do it to get pure and holy fire. But to us it is plain that they are really keeping up by unchanging custom a remnant of the ruder life once led by their remote ancestors. On the whole, these various ways of examining arts and sciences all prove that they never spring forth perfect, like Athene out of the split head of Zeus. They come on by successive steps, and where other information fails, the observer may often trust himself to judge from the mere look of an invention how it probably arose. Thus no one can look at a cross-bow and a common long-bow without being convinced that the long-bow was the earlier, and that the cross-bow was made afterwards by fitting a common bow on a stock, and arranging a trigger to let go the string after taking aim. Though history fails to tell us who did this and when, we feel almost as sure of it as of the known historical facts that the cross-bow led up to

the match-lock, and that again to the flint-lock musket, and that again to the percussion musket, and that again to the breech-loading rifle.

Putting these various means of information together, it often becomes possible to picture the whole course of an art or an institution, tracing it back from its highest state in the civilized world till we reach its beginnings in the life of the rudest tribes of men. For instance, let us look at a course of modern mathematics, as represented in the books taken in for university honours. A student living in Queen Elizabeth's time would have had no infinitesimal calculus to study, hardly even algebraic geometry, for what is now cailed. the higher mathematics was invented since then. Going back into the Middle Ages, we come to the time when algebra had been just brought in, a novelty due to the Hindu mathematicians and their scholars, the Arabs; and next we find the numeral ciphers, o, 1, 2, 3, &c., beginning to be known as an improvement on the old calculating board and the Roman I., II., III. In the classic ages yet earlier, we reach the time when the methods of Euklid and the other Greek geometers first appeared. So we get back to what was known to the mathematicians of the earliest historical period in Babylonia and Egypt, an arithmetic clumsily doing what children in the lower standards are taught with us to do far more neatly, and a rough geometry consisting of a few rules of practical mensuration. This is as far as history can go toward the beginnings of mathematics, but there are other means of discovering through what lower stages the science arose. The very names still used to denote lengths, such as cubit, hand, foot, span, nail, show how the art of mensuration had its origin in times when standard measures had not yet been invented, but men put their hands and feet alongside objects of which they wished

to estimate the size. So there is abundant evidence that arithmetic came up from counting on the fingers and toes, such as may still be seen among savages. Words still used for numbers in many languages were evidently made during the period when such reckoning on the hands and feet was usual, and they have lasted on ever since. Thus a Malay expresses five by the word lima, which (though he does not know it) once meant "hand," so that it is seen to be a survival from ages when his ancestors, wanting a word for five, held up one hand and said "hand." Indeed, the reason of our own decimal notation, why we reckon by tens instead of the more convenient twelves, appears to be that our forefathers got from their own fingers the habit of counting by tens which has been since kept up, an unchanged relic of primitive man. The following chapters contain many other cases of such growth of arts from the simplest origins. Thus, in examining tools, it will be seen how the rudely chipped stone grasped in the hand to hack with, led. up to the more artificially shaped stone chisel fitted as a hatchet in a wooden handle, how afterwards when metal came in there was substituted for the stone a bronze or iron blade, till at last was reached the most perfect modern foresters' axe, with its steel blade socketed to take the well-balanced handle. Specimens such as those in Chapter VIII. show these great moves in the development of the axe, which began before chronology and history, and has been from the first one of man's chief aids in civilizing himself.

It does not follow from such arguments as these that civilization is always on the move, or that its movement is always progress. On the contrary, history teaches that it remains stationary for long periods, and often falls back. To understand such decline of culture, it must be borne in mind that the highest arts and the most elaborate arrange

ments of society do not always prevail, in fact they may be too perfect to hold their ground, for people must have what fits with their circumstances. There is an instructive lesson to be learnt from a remark made by an Englishman at Singapore, who noticed with surprise two curious trades flourishing there. One was to buy old English-built ships, cut them down and rig them as junks; the other was to buy English percussion muskets and turn them into old-fashioned flintlocks. At first sight this looks like mere stupidity, but on consideration it is seen to be reasonable enough. It was so difficult to get Eastern sailors to work ships of European rig, that it answered better to provide them with the clumsier craft they were used to; and as for the guns, the hunters far away in the hot, damp forests were better off with gunflints than if they had to carry and keep dry a stock of caps. In both cases, what they wanted was not the highest product of civilization, but something suited to the situation and easiest to be had. Now the same rule applies both to taking in new civilization and keeping up old. When the life of a people is altered by emigration into a new country, or by war and distress at home, or mixture with a lower race, the culture of their forefathers may be no longer needed or possible, and so dwindles away. Such degeneration is to be seen among the descendants of Portuguese in the East Indies, who have intermarried with the natives and fallen out of the march of civilization, so that newly-arrived Europeans go to look at them lounging about their mean hovels in the midst of luxuriant tropical fruits and flowers, as if they had been set there to teach by example how man falls in culture where the need of effort is wanting. Another frequent cause of loss of civilization is when people once more prosperous are ruined or driven from their homes, like those Shoshonee Indians who have

taken refuge from their enemies, the Blackfeet, in the wilds of the Rocky Mountains, where they now roam, called Digger Indians from the wild roots they dig for as part of their miserable subsistence. Not only the degraded state of such outcasts, but the loss of particular arts by other peoples, may often be explained by loss of culture under unfavourable conditions. For instance, the South Sea Islanders, though not a very rude people when visited by Captain Cook, used only stone hatchets and knives, being indeed so ignorant of metal that they planted the first iron nails they got from the English sailors, in the hope of raising a new crop. Possibly their ancestors never had metals, but it seems as likely that these ancestors were an Asiatic people to whom metal was known, but who, through emigration to ocean islands and separation from their kinsfolk, lost the use of it and fell back into the stone age. It is necessary for the student to be alive to the importance of decline in civilization, but it is here more particularly mentioned in order to point out that it in no way contradicts the theory that civilization itself is developed. from low to high stages. One cannot lose a thing without having had it first, and wherever tribes are fallen from the higher civilization of their ancestors, this only leaves it to be accounted for how that higher civilization grew up.

On the whole it appears that wherever there are found elaborate arts, abstruse knowledge, complex institutions, these are results of gradual development from an earlier, simpler, and ruder state of life. No stage of civilization comes into existence spontaneously, but grows or developed out of the stage before it. This is the great principle which every scholar must lay firm hold of, if he intends to understand either the world he lives in or the history of the past. Let us now see how this bears on the
