l 1 of the paper which before the ink l would show had to be washed in 1 chemically purified water, dried, and. after that, treated with other chem icals. After the agents in Europe had l written their instructions in the in- 1 visible ink they would write with ordinary ink a letter presumably to a woman relative or some friend in the United States. The chemical which brought out tho invisible ink obliterated at the same time tho ordinary ink. Money From Neutral Country.
 Once the paper and ink problem had been solved the rest was com paratively easy. The source of the money used in financing the esplon- age system in England was discovered and in that connection 1t can be stated that the source was not the German embassy in Washington. The money was generally transmitted by express from a neutral country In Europe and addressed to Q person not actively connected with the spy system in this country. Eventually the money reached the persons in New York for whom 1t was intended.
 It was not the money part of the affair that first aroused the suspicious of the government agents. It came about this way: A few months ago Wunnenberg caused the arrest of one Robert Davis on the charge of stealing $4,0oo from him. Wunnen- berg said the money was part of a legacy left him by relative in Ger many, and that he had given the money to Davis to put into bank for him. The money, he said, was misappropriated. and Davis was ar rested. He was convicted in the su- preme court in Brooklyn last No- vember, and Justice Cropsey, before whom the case was tried, sentenced him to serve from two to four years in Sing Sing. where he is now.
 Both Sander and Wunnenberg blame Davis for the predicament in which they now find themselves. Wunnenberg had been on the Amer ican steamship Leelanaw and were on board that ship when it was tor pedoed by 8 German submarine in July, 1915. With the other surviv- ors of the wrecked ship, they were landed at Kirkwal. The Secret Serv- ice is now seeking to learn whether w u0HouUcTS "dS COllIACCCcu WILL LuS German spy system at that time.
 Blames Davis For Predicament.
 1T first met Davis," said Wunnen- berg yesterday, lon the Leelanaw, on board of which we were both en- ployed as engineers, and we were both together when tho ship was tor pedoed in the North Sea on July 25. 1915. The submarine which torpedoed us was the U41, and the commander was named Hansen. Captain Hansen saw to it that the crew was landed on the beach, and from England we were sent back to the United States. Returning to New York became connected with the Central Powers Film Exchange and I got Davis job with the company.
 Some time afterward Davis stole s4,00o from me, bought a gasoline boat and started south. We caught him and had him sent to Sing Sing and the ridiculous charges against Sander and myself are his work"
 Wunnenberg also said that several years ago he was in the United States service and had served on the army transports Sherman, Sheridan, Thomas, and Buford.
 The arrest of Davis and his pros
 ecution was brought to the atten-
 ton of the Secret Service, and, as
 result of investigation, the agents found the trail that on Monday night ended with the arrest of Sander and Vunnenberg.
 Bacon Is the only alleged spy whose arrest is admitted by the authorities. Two of the others. 1t Is said, are in ~71~ io k~ York as a. witness for the government against Sander and Wunnenberg and others who may be arrested in the fu- ture.
 A report which could not be ver- flied yesterday was that the German spy system now operating here is busy getting information about the land defenses and the navy of the United States.
