London Nov. 7.-London has been greatly excited by the report that a Germanowned musicprinting plant in
 NiIiesden, prominent manufactur- ing suburb of London. has an i'm. mense building whose heavy con eta foundations, floors and roof are well adapted to the use of siege guns
 Twenty of the German employees of the firm were taken ito custody and military experts are studying the building carefu ly Meantime the ex- cited public is fully convinced thai the plant was designed to act as a Herman base for attack upon London proper. The building unquestionablv occupies strategic position. It stands high, with a clear range to Crystal Palace. Willesden Junction. where two main lines enter London center, is but a short distance from the plant.
 However, the English architects who designed the building and super Vised it's construction eight years ago. say it is similar to many other print ing plants and has no heavier founda. tions and floors than are required where heavy machinery is to be in- stalled
 The building is about two hundred feet square on the outside and is con- structed about a court sixty feet square. It is but one story and the foundations are of concrete and six feet thick. The English manager of the concern says this unusually thick foundation was laid as the firm ex- pected to add additional stories to the plant when business expanded. A concrete roof covers most of the building
 Discovery by the allies that Ger many has prepared concrete bases. for Iits hoWitzers surreptitously in many places in Begium and France has made all Englishmen suspicious of possible German preparations in Eng land.
 In discussing the Willesden factory, the Sunday Times says: "In situa- tion which commands al almost un- interrupted view of that great tract of London which lies between Wilesden and the Crystal Palace is discovered a building whose roof, floor and found ations are constructed of exceptional ly thick concrete and might apparent ly he employed as the emplacemelt of a heavy gun m fact, one of those IT, inch howitzers for which such careful arrangements were found to have been made around Antwerp and Ma mur. We are very far from suggest ing that the premises at Willesden were deliberately arranged consid- ering the German workmed, it is at least probable that in the event of an attack upon London the attention Of the Germans commanders would have been called to that convenient con. crete floor, even if they had not known of it before their arrival.
 Tt is highly probable that there do exist such places around London and in the neighborhood of our great fortress positions which have been carefully prepared for siege guns, and the chief value, to our mind, of the Willesden discovery is that it may be expected to stimulate authorities to search for them.
 "The suspicion that many wireless equipments are operating in London was justified by the discovery of such a plant in the home of a German professor As wireless apparatus can be operated for so short distance as from London to the European coast without an outside tower the discovery of illicit wireless stations is very difficult The Times advocates that the War Office issue a statement stipuIating that persons found shelter
 ing such apparatus will be treated as spies and handed over to military uOWer"
