The comparatively large number of men-of-war mentioned is accounted for by the fact that at this time the _Karlsruhe_ began to make her presence felt by sinking more merchant ships, which caused no little apprehension amongst the mercantile communities in all the ports on the north and east coasts of South America, Brazilian firms at this period refusing to ship their goods in British bottoms, although some British vessels were lying in harbour awaiting cargoes. The German ship's activities were mainly confined to the neighbourhood of St. Paul's Rocks, Pernambuco, and the Equator. It is not easy to put clearly the disposition of the ships acting under Admiral Cradock at this time, nor to give an adequate idea of the many disadvantages with which he had to contend. The difficulties of communication on the east coast of South America between his two squadrons were very great, on account of the long distances between them (often some thousands of miles and always greater than the range of our wireless). The only method found feasible was to send messages in code by means of passing British merchantmen--usually the Royal Mail liners. The inevitable result of this was that it was frequently impossible for Admiral Cradock to keep in touch with his northern squadron, and important matters of policy had thus to be decided on the spot, the Admiral being informed later. On the rare occasions that our ships visited Brazilian ports, which were crowded with German shipping, the crews of these ships, having nothing better to do, would come and pull round our cruisers--in all probability cursing us heartily the while--much to the interest and amusement of our men. These visits could only take place at the most once every three months, when the opportunity of getting a good square meal at a civilised restaurant was hailed with delight by those officers who were off duty. Our coaling base in these waters was admirably selected. There was sufficient anchorage for a large number of ships four or five miles from any land, but protected from anything but a heavy swell or sea by surrounding ledges of coral awash at low water. Sometimes colliers got slightly damaged by bumping against our ships when there was a swell, but in other respects it suited its purpose excellently. The Brazilians sent a destroyer to investigate once or twice, but could find nothing to arouse their susceptibilities, for our ships were always well outside the three-mile limit. Our sole amusement was fishing, frequently for sharks.
