Engineer Brousneff, who was sent out in 

 the spring of 1903 by the Imperial Academy 

 of Sciences, at St. Petersburg, in company 

 with Lieutenant Kolchak and a number of ex- 

 perienced Yakuts, towards New Siberia and 

 Bennett Island, to search for the Polar ex- 

 pedition headed by Baron E. Toll, has re- 

 turned without results. The academy has 

 issued the following notice : Baron Edward 



Toll, chief of the polar expedition sent out 

 by the Academy of Sciences, left the Bennett 

 Island, lying north of New Siberia, on Oc- 

 tober 26 (November 8), 1902, taking a south- 

 ern direction. He was accompanied by the 

 astronomer Seeberg and two Yakuts. The 

 party seems to have been carried away by the 

 ice. As the researches hitherto made have 

 been in vain, a reward of 5,000 roubles (about 

 $2,500) is ofl^ered by the Academy of Sciences 

 for finding the whole expedition party, or any 

 part of it, and a reward of 2,500 roubles for 

 giving the first exact indications of tracing 

 the party.

 1904. The quarter-century anniversary hap- 

 pened to fall near the date set for the opening 

 of the Louisiana Purchase Exposition at St.

 exhibit. It is hoped that this exhibit will 

 increase the popular interest in the survey, 

 and in this connection it has been thought
