TILE AND PIPE DRAINING. 119 



with their general account of the process. This was executed 

 exactly according to the directions of Mr. Smith, of Deanston, 

 with tiles, and a foot of broken stone laid in upon them ; and 

 before the pipe tiles had received so much of the public appro 

 bation as has since been deservedly bestowed upon them. 



&quot; The accompanying map represents that portion of the lands 

 in the town land of Carnesure, which has been thorough-drained 

 up to the present time. Another part of the farm, in the town- 

 land of Comber, containing 19i acres, was drained in 1841. 

 The specification on the map exhibits the quantities drained in 

 the respective years 1841, 1842, 1843, and 1844, each of which 

 comprised the portion which the course of cropping enabled 

 them to manure, and to place under green crops in the succeed 

 ing year. 



&quot; In the year 1843, they completed the thorough-draining of 

 58 A. 3 R. 7 P. statute measure, by the execution of 7172 statute 

 perches parallel, 793 perches submain, and 128 perches main 

 drains; and in 1844, 58 A. 1 R. 37 P., by 7720 perches parallel, 

 781 submain, and 20 perches of main drains, being, in the years 

 1843 and 1844, 117 A. 1 R. 4 P. statute measure, viz. 

 14,892 perches statute of parallel drains. 

 1,574 &quot; &quot; &quot; submain &quot; 



148 &quot; &quot; &quot; main &quot; 



&quot; The mode of execution has been precisely the same as that 

 which Mr. Smith characterized as t most thoroughly following 

 out the Deanston system. In the whole of the land drained, 

 there is not one open channel for water ; all the water passes 

 away under ground, and the wheat seed on the potato land has 

 this year been covered with the grubber, without any ploughing, 

 after the removal of the potatoes, leaving the land perfectly flat, 

 and without a furrow, as recommended by Mr. Smith, so that 

 every stalk of grain will benefit equally from both the soil and 

 the atmosphere ; and during the late rains, even on sloping 

 ground, not a particle of the fine soil has been washed from the 

 land, while, in the undrained lands around, the roads and ditches 

 are filled with the fine deposits from the streams of water which 

 have rolled down the furrows, and the rivers are red with the 

 still finer matter which they are hurrying to the bottom of the sea. 

 This advantage is attained without any attendant evil ; they 

 look to the total abolition of every water-furrow from the fields &quot;
