THE ONONDAGA ACADEMY OF SCIENCES. 



The regular monthly meeting of the Onon- 

 daga Academy of Sciences was held March 17 

 in the rooms of the Historical Association in 

 Syracuse. Mr. Guy Bailey discussed the sub- 

 ject of bird photography. He showed some 

 admirable results of his work in this line. 

 He discussed the nesting and others habits of 

 many of our native birds. 



The April meeting of the academy was 

 held jointly with the Onondaga Historical As- 

 sociation in the latter's rooms on the evening 

 of April 20. Mr. J. S. Pennock, of the Sol- 

 vay Process Company, addressed the meeting 

 upon ' Alkali Industries.' The lecture was well 

 illustrated with stereopticon views and dealt 

 chiefly with the history of the Solvay process 

 and of the Syracuse plant.

Corresponding Secretary. 



the NEBRASKA ACADEMY OF SCIENCES. 



The fourteenth annual meeting of the Ne- 

 braska Academy of Sciences was held at the 

 University of Nebraska, Lincoln, on January 

 28 and 29, 1904, a goodly number of members 

 being present and a most enjoyable and profit- 

 able program being presented. 



The papers read were as follows : 



SiraUgrapMc Delineation of the Benton and 

 Niohrara Formations of Neirasha: G. E. 



CONDEA. 



In northeastern Nebraska these two forma- 

 tions have been much confused, owing to the 

 similarity in appearance of thd chalk rock 

 which occurs in each of the two layers, but 

 a layer of Carlyle clay 200 feet in thickness 

 on the average intervenes between them. 



The Fuel Value of the Common Cottonwood: 



C. E. Bessey. 



Weight for weight, cottonwood has a higher 

 fuel value than hickory, oak, or other woods 

 ordinarily used for fuel, though, bulk for bulk, 

 it is inferior. It also grows relatively more 

 rapidly, so that for Nebraska it is a more 

 valuable tree to plant for fuel than any other 

 of the varieties used for that purpose.
