DEPARTMENT OF PARKS. 1/7 



adam base, with sand filling, and a wearing surface of trap rock, 

 filled with Roa Hook gravel binder. The curbs and gutters are 

 of bluestone and Belgian blocks. 



Bay Parkway (Twenty-second avenue) is now macadamized 

 from Ocean Parkway to Cropsey avenue, the connecting six 

 thousand lineal feet having been constructed during the past 

 summer under a contract with John Maillie. The construction 

 is of the same character and under the same specifications that 

 governed the construction of Fort Hamilton avenue. 



The curb is of bluestone, and a traffic road of Belgian blocks, 

 fifteen feet in width, is located next to the curb on each side, the 

 centre driveway being thirty feet wide, which, with twenty feet 

 wide sidewalks, makes the total width of the Boulevard one hun- 

 dred feet. 



WAR ON TREE DESTROYERS. 



In anticipation of the attacks of the Tussock moth and the 

 elm beetle, a portable boiler and pump was constructed and at- 

 tached behind a 6oo-gallon sprinkler, the sprinkler containing the 

 arsenical preparation being connected to the pump by a suction 

 pipe, and also receiving a discharge pipe, which kept the poison- 

 ous matter in suspension by agitation. The capacity of the 

 pump is fifty gallons per minute, and is of sufficient power to 

 supply with strong pressure four leads of hose, one for distribut- 

 ing the mixture in the tank, and three for use on the trees. 



The machine was successful in checking these pests, and we 

 suffered little damage to foliage by their ravages. 



A detailed statement by the Engineer, William J. Zartmann, 

 of measurements and quantities of material and labor, is herewith 

 appended. 



Respectfully submitted, 



J. A. PETTIGREW, 



Landscape Architect.
