The number of tiles required, as estimated by the 

 plan, will be — 



2 inch, 146,300, costing (delivered at the dock), $2,194 50

6 " 12,400, " " " " 1,190 40 



Total, $7,179 90 



It is possible that a contract can be made to make and 

 lay the tiles, and dig and re-fill the trenches, at the fol- 

 lowing rates :

To which, adding $2,500 for the brick drains which 

 will be required, and $1,250 for the construction of the 

 proper outlets, would make the probable total cost of 

 the thorough drainage of the park, $28,337.74. As this 

 work should be commenced at once, I would recommend 

 that early steps be taken to place the tile on the ground, 

 when the work may be done by contract, or day's work, 

 as shall be deemed best.
