pick, and another with a shovel, to throw ont the loosened 

 earth ; •beginning - at the lower end, and each following 

 the other, deepening the ditch layer by layer, until it 

 has the required depth ; the relative expertness of the 

 men deciding which tools they shall use. Trial drains 

 should be run at each separate locality, to ascertain the 

 depth at which the water oozes from the ground into the 

 ditches, thus determining the depth of the drains. It 

 is probable that, in some instances, there will be required 

 small brick cylindrical drains to withstand the rush 

 of water at certain seasons of the year — the effect of 

 which will be lessened as the portion of the city adjoin- 

 ing the park, is built upon. 



Upon the plan which has been prepared has been 

 traced the principal streams, with the connections of 

 artificial drains deemed necessary to the thorough drain- 

 age of the ground. The positions of these drains will 

 be governed by circumstances ; but the general system, 

 as laid down, will remain essentially the same. At some 

 points the drains will be further apart ; at others, per- 

 haps, nearer together. It is believed, however, that the 

 scheme covers the maximum amount of expense that will 

 be required for this purpose. 



"Whether the work should be done by contract or day's 

 labor, could be very well decided by letting a small por- 

 tion of the ground by contract, as an experiment, while 

 a similar portion is undertaken by day's work ; the 

 result will soon determine the relative cost of each. 

 Any attempt to arrive at a calculation in any other way 

 would be absurd.
