The continuity of culture, even in civilized times, can only, however, be maintained by constant outlay, just as in arid districts a luxuriant vegetation needs continuous irrigation. The flood of Oriental wealth had to pour itself into Italy in order to bring forth the bloom of Renaissance art. Thousands of patricians, hundreds of temporal and spiritual princes, had to found and to adorn temples and palaces, gardens, monuments, pageants, games and household goods in order that art and science, schooling, mastership, discipleship and tradition might grow up. The worship of foreign culture which characterized Germany in the seventeenth and half of the eighteenth centuries only meant that our soil was grown too poor to yield a crop of its own. The culture of the Middle Ages remained international only so long as the population of Europe was too sparse and the opportunities of work too scanty to occupy local energies; even in the thinly populated, Homeric middle-ages of Greece, the builder and the poet were not settled in one place, they were wandering artists. If to-day the Republic of Guatemala or Honduras should want a senate-house or a railway-station they will probably send to London or Paris for an architect. Even technique in handicraft and industry, that typical art of civilization, cannot dispense with a great and continuous outlay on training, commissioning and marketing in order to maintain itself. Although it has not happened yet, there is no reason why a Serb or a Slovak should not make some important discovery if he has been trained at a European University and learnt the technical tradition. That will not, however, give rise to an independent and enduring Serbian or Slovakian technique, even though the costliest Universities and laboratories should be established in the country and foreign teachers called to teach in them. After all that, one must have a market in the country itself; expert purchasers, manufacturers, middle-men, a trained army of engineers, craftsmen, masters, workmen and a foreign market as well--in short, the technical atmosphere--in order to keep up the standard of manufacture and production. A poor country cannot turn out products of high value for a rich one; it has not had the education arising from demand. In products relating to sport and to comfort, for instance, England was a model, but in France these products were ridiculously misunderstood and imitated with silly adornments, while on the other hand French products of luxury and art-industry were sought for by all countries. German wares were considered to be cheap and nasty, until the land grew rich, and brought about the co-operation of its forces of science and technique, production and marketing, auxiliary industries and remote profits, finance and commerce, education and training, judgment and criticism, habits of life and a sense of comparative values.
