 here to some extent. 



A modification of the roof drainage of the power house 

 which was, last year, temporarily laid into a cesspool, was 

 found necessary during the autumn, and it was diverted tem- 

 porarily into an earthernware pipe opening on the surface of 

 the ground near the southwestern corner of the Garden ; the 

 storm water from the Southern Boulevard, which had given

 porarily diverted by an open ditch to near the same point. 

 The whole system of land drains south and west of the

 if possible, be extended this year to and across the Bronx 

 River so far as the stable and the propagating houses ; the 

 best method of accomplishing this is not yet apparent ; it has 

 not yet been possible to include it in any city contract. 



Grading. 



Grading operations outside the lines of building and road 

 contracts have been prosecuted by means of our teams and 

 laborers throughout the year, carrying out the provisions of 

 the general plan. 



A slope has been nearly completed along the south side of 

 the Southern Boulevard opposite the power house, thus mask- 

 ing and supporting the high stone wall which formed the 

 southern side of the road embankment at this point : it was 

 found impracticable to finally complete this slope, however, 

 in advance of the building of the new traffic road which is
