The "Powder Tower" looks out directly at a somewhat shabby building opposite to it. I have mentioned it before as standing on the site of an early monastic institution founded by those Irish monks who did so much towards bringing Central Europe into the fold of the Church. They were, in fact, the only missionaries, these pilgrims from the Isle of Saints, who took up the task in the fifth and sixth centuries, wandering far afield, through the German forests, along the great rivers Danube and Main, to Italy and Switzerland, where St. Fridian at Lucca and St. Gall in the hills above the Bodensee are still held in pious memory. The Saxon monk Winfrith, better known as St. Boniface, also deserved well of the people of Central Europe, for it was his zeal and energy which assisted Charles the Great in his colonizing achievements. In our own times other missionaries of Anglo-Saxon race, or at least English-speaking, penetrated to the darkest recesses of the Continent, even to Bohemia. They started as soon as the war was over and Europe again a safe place to travel in. They took their toilsome way, by _train de luxe_ and at Government expense, to such distant places as Prague and Vienna, even Buda-Pesth. They were of those who were indispensable while men were fighting, whose services could be spared when danger no longer threatened. They came deeply imbued with the importance of their mission, their commission, diplomatic, economic, hygienic, whatever it was. They came in scores, accompanied by willing and well-paid workers, to bring relief to those who had suffered in the war. They bought up the scanty supplies of the countries to which they brought the blessing arising out of their own high rate of exchange. They came in their hundreds to spread the light of learning in matters hygienic to Prague, the old university town famous for its school of medicine. They taught the young the blessing of western guilds or associations, the young of a country which forged its weapon of social defence, the Sokol, some seventy years ago. They expect a deal of gratitude for all this; they are also entirely devoid of any sense of humour, or they would all go home and keep quiet.
