A design for a park in one city will not be suitable for another, owing to varying natural features, as well as requirements which must be met. A soil in one locality will drain as readily and perfectly with drains 150 feet apart as others will with drains 40 feet apart, and upon this fact depends the distance apart that drains should be placed. It -Cvould be a waste of labor and material to place drains 40 feet apart in some of our soils, while, on the other hand, to place drains at intervals of 150 feet in some soils would come far short of accomplishing thorough drainage. The cost of the work has much to do with the dis-. 80 rods Fig. 20.—Drainage of a 40-acre Field containing Pond with Higli Land surrounding it, tance apart at which drains are usually placed, and thorough drainage is often sacrificed to this.
