108 REPORT OF THE SECRETARY. 



made where urgently needed. The expenditure for this purpose was 

 about $700. 



Driveway from Cathedral avenue. — It will be noted from the language of 

 the appropriation for the park that the entrance formerly specified to be 

 made from Woodley road is now to lead in from Cathedral avenue, a 

 street recently constructed along the western side of the park. An appro- 

 priation of $5,000 was made, winch included the necessary grading and 

 removal of earth. In pursuance of this provision of law, work was done 

 on the small dam made over Rock Creek near the site of the old Adams 

 mill in order to secure the hanks against high water and to permit the 

 stream to be safely forded. An illustration showing this ford is herewith 

 appended. From this point a fill is being made to connect this driveway 

 with Cathedral avenue. The heavy fill made by the District authorities 

 along the line of Cathedral avenue made it necessary to construct a rude 

 retaining wall at one important point to prevent detritus from washing 

 down and filling up the road. The amount appropriated by the act, 

 $5,000, has been used upon the driveway, and the work will be continued 

 during the next fiscal year. 



The raw slopes of earth that will remain after this driveway is completed 

 should lie planted at once with suitable shrubs and trees, in order that they 

 may be kept from serious erosion and to avoid the unsightly appearance 

 which they would otherwise present. 



Repairing roadways. — The driveway from the Adams mill entrance, 

 which is more used than any other road in the park, has been reshaped 

 and resurfaced with crushed limestone. This driveway assumes addi- 

 tional importance from the fact that the District authorities have at last 

 graded a carriageway from Columbia road to the park entrance, thus 

 making the driveway in the park more easily accessible. 



The main driveway throughout the park, from Quarry road to the west- 

 ern entrance, has been dressed with gravel, and the whole at a cost of $400. 



The Klingle road, which skirts the north side of the park, having been 

 repaired and raised by the District authorities, it became necessary to reset 

 the park fence and raise the grade of the driveway connecting with it. 



The cutting of Cathedral avenue through the western edge of the park 

 made it necessary to remove a considerable number of evergreen and other 

 trees anil shrubs formerly set in that locality for the purpose of a screen. 

 These trees were reset during the hot summer months along the roads and 

 walks in different parts of the park and the shrubs around the office build- 

 ing. Considering the extremely unfavorable weather when the transfer 

 was made, this planting was fairly successful. A considerable amount of 

 stock was transferred from the nursery to permanent localities, and the 

 care of the natural forest of the park has been continued as necessary. The 

 total cost of this work during the year was $900. 



Children' s room at the Smithsonian Institution. — A small exhibit of iishes 

 and birds belonging to the National Zoological Park has been installed and 

 maintained in the children's room at the Smithsonian Institution. The 

 total expenditure for this purpose was about $400. 



Sundial. — The sundial purchased in London by the Secretary from a pre- 

 vious appropriation was set up on the lawn near the animal house, at a cost 

 of $100.
