the Mayor August 4, will be expended in the continuation of con- 
struction of driveways and paths, principally on the eastern side 
of the grounds, in the completion of the grading operations neces- 
sary at the museum building, in the extension of the system of 
water-supply and drainage, and for minor works. All the earth 
and rock to be excavated at the museum building is required for 
filling and for the telford foundation of roads and paths, so that 
the same money will effect two pieces of work, as has been the 
case in nearly all the grading operations hitherto accomplished, 
a result made possible by following the original plan of de- 
velopment approved by the Board of Managers in December, 
1896. It is now planned to complete the driveway system and 
to build at least an additional mile of paths.
