one State to another, nor in any wise interfere with commerce between the States.

By these means a Constitution may prevent the disruptive forces in a country from threatening the stability of the central government or the unity of the State. To remove part of the material on which they might work is to weaken their working, and to divert into safe channels the political activity they would evoke. Although a Flexible Constitution may accomplish this, if those who work it respect certain fundamental principles and treat their querulous minorities in a conciliatory spirit, the work is best done, and usually has been done, by a Rigid Constitution, because this latter provides a guarantee to minorities, or to subdivisions of the country, stronger than they can have under an omnipotent legislature. In fact the existence of the grounds of contention and possibilities of disruption we have been considering is among the chief causes which have called Federal Governments and Rigid Constitutions into being.

One further observation should be made before quitting this part of the subject. Racial differences and animosities, which have played a large part in threatening the unity of States, are usually dangerous only when the unfriendly races occupy different parts of the country. If they live intermixed, in tolerably equal numbers, and if in addition they are not of different religions, and speak the same tongue, the antagonism will disappear in a generation or two by social intercourse and especially by intermarriage. When the right of full legal intermarriage had been established, the fusion of the patricians and the plebs at Rome began. So

the Northmen in the tenth and eleventh centuries, so the Norman-French in the eleventh and twelfth centuries, became blent with the English. The Magyars and Saxons, though generally occupying different parts of the country, and to some extent retaining each their own speech, have in Transylvania now begun to melt into one. It is the fact that they not only speak a different tongue but also profess a different faith that keeps the Rumans of that province apart from both Saxons and Magyars; and even these differences might in time cease to operate did not these Rumans look across the mountains to a large Ruman State into which they would gladly be absorbed. But in one set of cases no fusion is possible; and this set of cases forms the despair of the statesman. It presents a problem which no Constitution has solved. It is the juxtaposition on the same soil of races of different colour.

This is a recent phenomenon in history. In the ancient world, almost all the barbarous tribes whom Rome subdued and brought into her Empire were sufficiently near the Italians and Hellenized Asiatics in physical characteristics for intermarriage to go on freely. The Carthaginians, who to be sure were not numerous, seem to have soon lost their distinctive nationality: and that the Jews remained distinct was their own doing, not that of the conquerors1. Even as towards Egyptians and Numidians, who were certainly dark, one hears of little repulsion. Besides, both races were intelligent, and

the former in their way highly civilized. With the African slave trade a new and a dolorous chapter in history opens. In our own time it is the settlement of Europeans in countries where the native holds his ground against the settler, as the Kafir does in South Africa, and the aboriginal Peruvians and Araucanians do in Western South America, or it is the influx of coloured immigrants, like that of the Chinese in Western America and the Hawaiian Isles, that raises, or threatens to raise in the future, this problem in an acute form. A community in which there exist two or more race-elements physically contrasted and socially unsusceptible of amalgamation cannot grow into a really united State. If the coloured people are excluded from political rights, there is created a source of weakness, possibly of danger. If they are admitted, there is admitted a class who cannot fully share the political life of the more civilized and probably smaller element, who will not be consoled by political equality for social disparagement, and who may lower the standard of politics by their incompetence or by their liability to corruption. If the people of colour are dispersed over the country among the Europeans, instead of dwelling in masses by themselves, they may not act as a centrifugal force, threatening secession, but they are a serious hindrance to the working of any form of popular government that has been hitherto devised, for they divide the population, they complicate political issues, they prevent the growth of a genuinely national opinion.

The most noteworthy attempts that Constitutions have made to deal with these cases have been made in the United States, where the latest amendments to the

Federal Constitution provide protection for the negroes and forbid the States to exclude any person from the electoral suffrage in respect of race or colour, and where several recent State Constitutions have devised ingenious schemes for disfranchising the vast mass of those whom these very amendments have sought to protect. So far as political rights are concerned, the problem is very far from having been solved in the United States. But as regards private civil rights, it has certainly been an advantage to the negroes that the Federal Constitution guarantees such rights to all citizens: and probably in any country where marked differences, with possible antagonisms, of race exist, it will be prudent to place the private civil rights of every class of persons under the equal protection of the laws, and to make the rights themselves practically identical. It would lead me too far from the main subject to describe the ways in which similar problems have been dealt with in Algeria, in South Africa, and in some of the other colonies of European nations. Nowhere has any quite satisfactory solution been found1. But the case of New Zealand deserves to be mentioned as one in which the experiment has been tried of giving parliamentary representation to the natives, who mostly live apart on their own reserved lands. So far, the results have been good. The conditions are favourable, for the Maoris are a brave and intelligent race, and they are now too few in number to excite disquiet.

It was the good fortune of the Roman Empire that the vast majority of the races whom it conquered and

absorbed had no conspicuous physical differences from the Italians which prevented intermarriage and fusion. Race and birthplace were no great obstacle to a man of force. Two or three of the Emperors were of African or Arab extraction. Moreover, the peoples of Southern Europe seem to have less repulsion of sentiment towards the dark-skinned races than the Teutons have. The Spanish and Portuguese intermarry not only with the native Indians of Central and Southern America, but also with the negroes. The French of Canada intermarried more freely with the Indians of North America than the English have done.

Summing up, we may say that the aim of a wellframed Constitution will presumably be to give the maximum of scope to the centripetal and the minimum to the centrifugal forces. But this presumption is subject to two countervailing considerations. One is that the energy of civic life may be better secured by giving ample range and sphere of play to local selfgovernment, which will stimulate and train the political interest of the members of the State, and relieve the central authority of some onerous duties. The other is that the centrifugal forces may, if too closely pent up, like heated water in the heart of the earth, produce at untoward moments explosions like those of a volcano. Hence it is well to provide, in the Constitution, such means of escape for the steam as can be made compatible with the general safety of the State. Where a Constitution, and especially a Rigid Constitution, has been framed with due regard to these considerations, and turns to account the methods already discussed, it may itself become a new centripetal force, a factor making
