[FROM OUR SPECIAL CORRESPONDENT] BERLIN, Sept. 17 — I have received a number of details on the alleged arrest of the Russian Naval Attaché, M. de Dubassoff, while making plans of the fortifications at Pillau. A high functionary of police has been sent in all haste to Pillau to hold an inquiry into the affair. At the Russian Embassy nothing can be learned. The officials of the Embassy deny in toto the charges made against M. de Dubassoff.

I understand, however, that the secret political police here have been watching the movements of certain high functionaries of the Russian Embassy suspected of organising a far-reaching system of espionage. Three years ago, the police here arrested the secretary of Baron Krieger, the former Russian Naval Attaché, in flagrante delicto of espionage. Though it was well known that he had been acting under the instructions of his employer, the German Government did not wish to make any scandal, and confined themselves to demanding the recall of Baron Krieger.

HIS RECALL DEMANDED

This time, however, it is the Attaché himself who is suspected. It is stated that the German Government will insist on his immediate recall. I give this report under all reserve, for it is doubtful if Count Caprivi will take such a serious step and one so likely to deeply offend the Government of the Czar. It is, however, certain that for some time past, M. de Dubassoff’s movements have been closely watched by the secret police, which declares that it has in its possession proofs of the existence of an immense network of espionage organised by certain functionaries of the Russian Embassy and directed from Berlin.

The speech of Prince Bismarck on the Polish question has caused a great sensation in Court circles here, as it amounts to a severe criticism of the Emperor’s policy vis-à-vis the Poles. In fact, part of the ex-Chancellor’s speech was addressed to the Emperor directly, blaming his relations with what is known as the Polish Court party, which is led by Baron Koscielski and his beautiful wife, and which enjoys a large measure of the Imperial favor. Even the Liberal press, which is, as a rule, hostile to the Chancellor, approves his utterances on this occasion without reserve. The Prince has undoubtedly touched a national chord in his speech, and one which will meet with the approval of all parties.
