SCIENCE AND INDUSTRY.

The Lansing skull" supposed to be the oldest human remains ever found in America, and which was dug up not l 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 minute inspection of the skull, and | it was agreed that the age of this bone outranks 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 and H. A. Long.
 The twenty-second annual reunion of the Old Time Photographers will take place on September 10, II. F at Salt Lake City. The United States military corps will meet at the same time and place.
 The schooner John Smeaton recently broke all previous cargo records held on the great lakes, carrying 7,461 tons of ore. The best previous record of this vessel was 7413 tons, which had only been exceeded by the Edenborn. of the same line, which on one occasion car ried 7417 tons.
 Tie Nernst lamp was very extens- | lively used for decorative purposes dur | ing the recent festivities in honor of the crOwning of King Edward. A tri- umphal arch erected across one of the | AL mated almost entirely with these lamps. | all the prominent lines of the structure were followed by the lamps. each giving very brilliant white light of from 160 to 1S0 candle power. The total number of lamps used was $50, making an inn mense total of 6O,OOO candle power. Lord Kelvin is said to have uttered the belief after a careful consideration of the subject of wireless telegraphy that the shareholders in submarine cal ble 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.
 
 pany, recently organized, announces that it is in a position to make propo- sals for 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 a part of the weight of the airship.
 There has been recently completed at Kansas City a locomotive designed foi use in a Mexican mine. in which gas oline is used as fuel. The mine wherC this engine is destined for service is 1S0 miles from the nearest railway, anC the engine had to be designed with tho view of transportation to the point oi delivery on mule back, and, therefore no individual part was allowed to weigf more than 200 pounds. To prevent th' escape of fumes in service. provision i: made for the purification of the ga: escaping from the engine, which i! washed in the same way as illuminat ing gas is passed through scrubbers a the gas works.
 Prof Reginald Fessenden. formerl! connected with the weather bureau, ha: recently received a number of patent! covering his system of wireless teleg raphy, and he is at the head of a com pany recently organized. which vii soon engage in the manufacture an' sale of instruments used. The Fessen
 den system has been tried by tn
 weather bureau and the war depart
 ment and is said to be in many respect
 superior to any of the others now il
 use.
