CANALS OF MARS.Professor Lowell Says That They Hat* Begun to Double.Boston, Mass., November 21.—A dispatch was received to-day from Percival Lowell at the Lowell Observatory, Flagstaff, Arizona, stating that the canals of Mars, as observed last night, have begun to double and that Phison and Euphrates were seen geminated. The duplication of the canals and the planets is a phenomenon for which astronomers have been watching with great interest. It was first observed by the Italian Astronomer Schiapparelli a number of years ago. He announced that some of the straight lines, which are known as canals, were to be seen accompanied by aCarallel line, a9 if another canal existed, eside the first. During the different oppositions of Mars the canals have been closely watched to learn more about the duplication. The first European astronomer to observe the phenomenon was Perrotin at Nice, who in two successive observations observed duplication. In this country the canals were observed doubled by the Lick Observatory in 1890, and again in 1892. During the present position one canal only has heretofore been announced as double, this being Ganges. The observer of this was Professor Holden of Lick. Observations of the same canal since that time have not shown it to be continuously double. The cause of the duplication is by no means determined. Mr. Lowell is of the opinion that it is dependent upon the season, and has predicted all along that the canals would not be seen in duplicate until some time in November.TETK1K1CQCCC I VKICUCDC
