156 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1964 



ford and continuing down through Kock Creek Park. This is part 

 of a program of sewage improvement of the District of Columbia. 

 Unfortunately the installation of such a large sewer necessitated the 

 removal of most of the trees along the west bank of Rock Creek, and 

 also the closing of the fords for many more days this year than is 

 normal. 



At various times during the year there was construction going on 

 in five different areas of the Zoo. This caused some inconvenience to 

 visitors and necessitated changes in their parking and established 

 traffic patterns. These changes, however, were met with ready ac- 

 ceptance by the visiting public and a great deal of friendly interest 

 by local citizens. 



There was a drop in the number of organized bus groups visiting 

 the Zoo because of the difficulty of parking buses during the con- 

 struction program. 



All redevelopment work is being done under the direction of the 

 District of Columbia Department of Buildings and Grounds. Spe- 

 cial acknowledgment is due the director of that department and his 

 able staff. 



Respectfully submitted. 



Theodore H. Reed, Director. 

 S. Dillon Ripley, 



Secretary, Smitlisonian Institution.
