Such evidence as the prosecution gave, as shown in the foregoing report, is worthy of very careful attention with regard to the working of the espionage system. For such a post as that which Ernst is alleged to have filled is but a link in a chain, and the chain is a long one. CHAPTER TWELVE. OTHER RECENT CASES. BIBLIOGRAPHY. The work of the supply ship captured recently in a port on the east coast of Scotland hardly comes within the limits of this book, but it is significant as showing the daring of German methods, which apparently include the obtaining of supplies from an enemy's country by means which endanger neutral shipping--so long as the neutral ships can be found to take the risks. It was noted by the naval authorities that German submarines had been displaying activity at such a distance from their legitimate ports of supply as to render probable and almost certain the existence of other sources of supply. A watch was consequently kept for suspicious neutral shipping, and in the end a capture was made. A vessel came into port and proceeded to load for departure, and the customs officers could find nothing wrong with her. Her papers were in order, her cargo contained nothing in the nature of contraband of war, and there was no cause for detaining her, as far as could be seen. But there were noted on the deck of the vessel, neatly coiled, cables and cables, enough to furnish a whaler on a three-years' sailing voyage and leave over sufficient to start a ropemaker in business. All over the decks bulky coils of hawser lay, and though, at any other time, the hawsers might have passed without notice, it was felt by the customs men that the superabundance of rope justified further investigation than had already been bestowed on the boat. So one of the coils was unfastened, its wrappings removed, and the cable itself was uncoiled. Then was it found that there was merely a shell of rope, which served as covering for a steel drum containing oil fuel suited for the use of submarine engines. And there the story ends. The other case which I propose to quote shows equal audacity. At the Guildhall Court there appeared, on October 5, George Newton Spencer, who described himself as a clerk, and gave his address as Lubeckerstrasse, 33, Hamburg, Germany. He was charged with "unlawfully inciting Mr Frank Henry Houlder (Houlder Brothers, Limited, Leadenhall Street and Liverpool) to trade with the enemy."
