Chicago, April 5.- Reports received by the election commissioners indicated that the vote cast at the polls would probably range from 160,000 to 175.000. This estímate means that not more than 50 per cent. of the registered vote waa polled. While far below the presidential and mayoralty vote, these figures exceed those of the last election - the judicial election held in June, 1897 - when but 145,000 votes were cast. Lack of interest in many wards and the raw weather combined to keep the vote down.
