SCIENCE AND INDUSTRY.

The Lansing skull" supposed to be the oldest human remains ever found in America. and which was dug up not long ago near Lansing, now reposes in the Kansas City museum, where it is the object of much curiosity and spec ulation by scientific men. A delegation recently visited the museum and made a minute inspection of the skull and it was agreed that the age of this bone Cutranks anything heretofore discov- cred in this country. The delegation mentioned consisted of the following: Prof. Winchell of Minneapolis; Warren Upham of St. Paul. Erasmus Howarth, geologist of the University of Kansas City: s. w. Willis, paleontologist of the University Of Chicago. The gen. tlemen were received by Sidney J. Hare i. and H. A. Long.

 The schooner John Smeaton recently broke all previous cargo records held on the great lakes, carrying 1,461 tons of ore The best previous record of this vessel was 7.413 tons, which had only been exceeded by the Edenborn, of the same line, which on one occasion car ried 7.417 tons.
 The Nernst lamp was very extens- lively used for decorative purposes dur ing the recent festivities in honor of the crowning of King Edward. \ tri- umphal arch erected across one of the thoroughfares was brilliantly illumi-
 .r.- Ill the prominent lines of the structure were followed by the lamps. each giving a very brilliant white light of from 16O to 1S0 candle power. The total number of lamps used was $50, making an i'm mense total of 60O00 candle power.
 Lord Kelvin is said to have uttered the belief after careful consideration of the subject of wireless telegraphy that the shareholders in submarine cable companies need not be alarmed at the prospect of an active competition from the wireless system.
 An aluminium alloy is now used as q substitute for copper in the manufac- ture of nails and tacks. The white metal is much cheaper and in every way as durable and desirable as copper.
 The United States Shipbuilding com pany, recently organized, announces that it is in 6 position to make propo- sals for a complete vessel with armor guns forging machinery, and hull. No other plant in the world can do this.
 It is announced that Prof. Alexander Graham Bell is personally supervising the construction of an airship at his home at Baddeck, Cape Breton. It is said that Prof. Bell has given consid- erable thought to the subject of aerial transportation for many years, and has already spent many thousand dollars in experimenting. The aeroplane prin- ciple is used largely by Prof. Bell, al > though provision is made for a gas containing bag with which to sustain part of the weight of the airship.
 There has been recently completed at Kansas City locomotive designed for use in a Mexican mine. in which gas oline is used as fuel. The mine where this engine is destined for service is 1S0 miles from the nearest railway, and the engine had to be designed with the view of transportation to the point of delivery on mule back. and, therefore no individual part was allowed to weigh more than 200 pounds. To prevent the escape of fumes in service provision is made for the purification of the gas escaping from the engine, which IS washed in the same way as illuminat- ing gas is passed through scrubber3 at the gas works.
 Prof. Reginald Fessenden. formerly connected with the weather bureau. has recently received a number of patents covering his system of wireless teleg- raphy, and he is at the head of com pany recently organized, which will soon engage in the manufacture and sale of instruments used. The Fessen- den system has been tried by the weather bureau and the war depart ment and is said to be in many respects superior to any of the others now in use.
