USE WILD DUCKS ID
 KILL MOSQUITOES
GERMAN SCIENTIST FINDS A NEW ERADlCAToR FOR THE LITTLE
 MALARIA CARRIER.
Wild Ducks Feed on the Larvae and in Short Time Mosquitoes Are an Un- known Quantity.

Berlin, December 20.-The most et-
 fecitve method of exterminating mos
 quitos, says Dr. Gebbing. director of
 the Leipzig Geological Garden, is to
 keep wild ducks on the pounds where hey breed. These birds feed eagerly upon all insect life in the lavae state and where there are plenty of ducks very few of the lavaa reach the glories of mosquitohood, even in most stag nant pools.
 Dr Gebbing gives numerous cases
 to substantiate this claim. Count vOn
 Williamowitz and Mollendorff, chair
 man of the German Society for the
 Protection of Bird Life, says that his estates were infested with misquitos
 till, some years ago, he stocked his
 ponds with thousands of wild ducks.
 Dr. Heinroth one of the keepers of the Berlin Geological Garden, a spec
 ialist on the habits of ducks, points out that there has been a great dim-
 mutton of the mosquito pest in the park, since wild ducks were introduc- ed some years ago on it's lakes and stagnant water courses. Dr. Gebbing
 has had equal success with his own experiments at Leipsic.
 The sale of the Vossische Zeitung, the oldest newspaper in Berlin, known affectionately to German readers as "Aunti Voss," to the Ullstein syndi cate, calls attention to the develope- ment of newspaper trusts in Germany which in Berlin for example, have gathered most of the live and paying publications into three big groups.
 The Ullstein company, or rather family is one of the most vigorous of these. It now publishes five dailies in Berlin. including the Vossisshe, the Morgenpost and the ZeitungamMittag tor Noon Gazette). and eight weekly and other publications, covering such fields as sport, fashions and the illus trated weekly for family circulation The Lokal Anzeiger owned by The August Scherl Company, forms the nucleus of another groupe of papers, consisting of the three dailies in Der lin, one in Hamburg and about ten weekly and other publications. Ru- dolph Mosse, owner of the Berlin has two other dailies and several weekly publications. The three firms are united in cOmmun- ity of interest by a joint contract, 1 pledging them to assist each other 1 in case of strikes, etc, and to start no new riveal papers.
 In addition, the owner of the Taqe | batt is. or was the second largest | SUNDAY GAL FOUR
 stockholder in the August Scherl | Company. It is reported however, ! that the entire Scherl property has | been acquired by a group of Conser- | vative capitalists who propose to use | it's publications for vigorous propagan- | da in the interest of the Conservative | party
 The Ullsteins it is understood, will | continue the Vossische Zeitung along | the lines that have always given it it's | character, but they hope | to deyelope it as business undertake ing This vederable dOurnal-it is 20f years old-has had to make a | hard struggle against the more mod. | ern type of newspapers that have | lately became popular at Berlin. For | more than a century the property of | the Leasing family, 1t passed two i years ago into the hands of a syndi- cate to newspaper reports, $2,140 900, | The syndicate now sells it at a price 1 variously reported to be between S1,- | 00O,000 and Si,700,000 The loss, 'here- | fore. to the bankers has been consid- | erable.
