106 YALE AGRICULTURAL LECTURES. 



The items of the cost of drainage are, 1st. Engineering. 

 Employ a competent engineer to get the levels, and locate the 

 drains and make a plan, so that the drains may be readily found. 

 2d. Excavation, which is less for this than any other drains. 

 3d. The cost of tiles and freight. At thirty-three feet apart, 

 1,320 pipe will lay an acre, reckoning a foot to each pipe. 

 4th. Collars, if used. 5th. Outlets, a small but necessary item. 

 6th. Laying the pipes, a small cost, as a man can easily lay one 

 hundred and sixty rods in ten hours. 



The total cost of draining four feet deep, with tiles at ten 

 dollars per thousand, was estimated at fifty cents a rod. If the 

 excavation is but three feet deep, it will reduce the cost to 

 thirty-three and a third cents, as it costs twice as much to exca 

 vate a ditch four feet as three feet. 



The comparative cost of stone and tile drains was given; 

 the cost of tile drains as above that of stone drains at more 

 than twice as much, the excavation being twenty-one inches 

 wide, and two loads of stones at twenty -five cents each, making 

 the cost of these two items at one dollar a rod. Then add 

 twenty-five cents per rod for laying the stones, and we have 

 one dollar twenty-five cents per rod for stone drains, against 

 fifty cents for tiles. Judge F. concluded with an exhortation 

 to farmers to drain with stones if tiles cannot be procured ; but 

 not to be satisfied with their operations until they have tried 

 tiles at four feet depth.
