SCIENTIFIC LECTURE— VII. 



THE COLORADO PLATEAU— ITS CANOXS AND 

 RUINED CITIES. 



By Prof. J. L. Newberry. 



The aiidiencG at the last lecture of the Scientific Course was 

 numerous and appreciative. Prof. S. D. Tillman presided, and, in 

 introducing the lecturer, said : 



Ladies and Gentlemen. — The lecture of this evening will termi- 

 nate our course for this winter. The trustees have the satisfaction 

 of knowing that every promise made at the commencement of the 

 course has been literally fulfilled. They are fully aware of the 

 diversity of the subjects discussed, and they have no doubt that 

 more good would have been attained if a single branch of science 

 had been presented, thus connecting the whole series of lectures. 

 Such a systematic method cannot be followed efi'ectively, unless the 

 Institute owns complete philosophical apparatus, and gives the lec- 

 turer every facility for illustrating his subject before a large audi- 

 ence by means of diagrams and experiments. It is for this and 

 many other reasons, that the members of the American Institute are 

 anxiously looking forward to the time when it shall have a perma- 

 nent abiding place in a magnificent structure commensurate with its 

 wants and worthy of its name. [Applause.] Until that time we 

 must be contented with the quarters we have. The trustees are 

 gratified to find their example has been followed by officers of simi- 

 lar organizations in other cities, and that a new era has dawned since 

 scientific lectures have become one of the fashionable attractions ; 

 and present appearances indicate that the lecture-loving public Mill 

 not rest contented until every department of science has been thor- 

 oughly set forth in the lecture-room. [Applause.] I have now the 

 pleasure of introducing Prof, Newberry, of Columbia college.
