ANNOUNCEMENTS 



The Board of Managers of the National Geographic Society begs to 

 announce to the resident members that aljout 200 responses to circular 

 letter of October 18, 1900, have been received. A very large majority 

 of the replies favor a reduction of the number of lectures by dropping 

 either or both the Lenten and Technical courses. 



With this i)ositive expression of ])reference on the part of the res- 

 ident members, and in view of tlie proljable increase in cost of the 

 Technical course, due to the fact that a more expensive hall than that 

 of Columbian University would have to be secured, the Board has 

 decided to discontinue the Technical course during November and 

 December and to omit the Lenten course of the present season. The 

 Popular course at the Congregational Church will be given as here- 

 tofore on alternate Fridays, beginning Frida}', November 9, 1900.

 preliminar}' notice of the lectures during November and December 

 will 1)6 nuiiled in a few da3's.
