280 EXPERIMENTS IN DRAINING.

examination, it appeared necessary to possess a 

 piece of ground belonging to a neighbor, that I 

 might secure a good and sure outlet for the water 

 from some of my upland fields that required drain- 

 ing in places. With this view I purchased 10 -f/p 

 acres of low land saturated with water. A part of 

 this land, say about four acres, from twelve to 

 eighteen inches of the surface was a black vegetable 

 mould lying on a stratum of clay of the same depth, 

 under which I found a hard bottom for my tiles, not 

 over three feet in depth ; I felt persuaded that those 

 ten acres were wet from my own upland, as well as 

 from my neighbor's wet land adjoining. The first 

 ditch I dug was directly on the line betwixt the land 

 I got of my neighbor, and that he still owns. This 

 I found cut off all the water on that side. I then 

 commenced draining that 10 T V<r acres ; also about 

 thirty acres of upland : a large proportion of the 

 upland did not require draining. In the two pieces, 

 which, made into one field, contained about forty 

 acres, I laid 1,072 i rods of drain which have drained 

 the whole extent in a thorough manner. The flow 

 of water is so large at times, I was compelled to 

 use a large number of the largest sized tiles ; and 

 for main drains, as I had to have three, I had to lay 

 double rows of four-inch tiles ; and in one locality I
