THEFTS FROM A RUBBER FACTORY. 



The discovery has been made that the Continental Caoutchouc 

 und Guttapercha Compagnie (Hanover) have been the victims of 

 extensive robberies and defalcations. The thieves, who have been 

 at work for a consderable time past, have stolen considerable 

 amounts of rubber goods of every description, although they ap- 

 pear to have given the preference to bicycle supplies and pneu- 

 matic tires for motorcycles. They disposed of their booty by 

 selling it to bicycle dealers. The band of robbers was composed 

 of workmen in the company's night shift. The fact that several 

 of the thieves spent a great deal more money than their earnings 

 warranted led to the discovery of the thefts. The men were 

 watched, and it was found that their knowledge of the works 

 was exceedingly useful to them. They removed the stolen goods 

 from the works through a secret passage, unseen by the door- 

 keeper, who would otherwise have barred their way. Six per- 

 sons, all of whom have been arrested, were concerned in the 

 thefts. A book kept by one of the members of the gang shows 

 that the thieves were doing a flourishing business. The goods 

 taken and disposed of were regularly entered in the hook, which 

 is consequently a rather important item of evidence in the hands 

 of the police. A large lot of the stolen goods which had not as 

 vet been sold was recovered 1'}- the detective bureau. — Gummi-
