Two important additions to the series of North American habitat 
groups have recently been completed. ‘These are the Duck Hawk 
group, representing a scene along the Palisades of the Hudson River, 
and the Hackensack Meadow group, which represents a section of this 
familiar range and the nesting habits of the birds which frequent it in 
August. 
TuE fall exhibition of the Horticultural Society of New York was held 
at the Museum November 17-20. ‘The number of entries was large, 
and the display of cut flowers and potted plants was most attractive, 
particularly in the classes of chrysanthemums, orchids and carnations. 
THREE floors of the new Columbus Avenue wing of the Museum 
have been set aside for the exhibition made by the Committee on the 
Prevention of Tuberculosis of the Charity Organization Society of New 
York, temporary stairways having been installed, so that ready access 
is had from one floor to the next. This exhibition aroused widespread 
interest during the time that it was held in connection with the recent 
International ‘Tuberculosis Congress at Washington, and it is evident 
that it will attract even more attention and be visited by more people, 
while it is on view at the Museum. The exhibition is open free to the 
public during the usual hours and wiil continue for several weeks. 
Entrance to it may be had through the temporary doorway at the north 
end of the new wing, at the corner of Columbus Avenue and Seventy- 
ninth Street, as well as through the usual public entrance on Seventy- 
seventh Street.
