A very successful trial of Reid and Gray's drain plough took place on Mr E. Ruddock's farm, Southbridge, on Thurs day last. This implement is the first of the kind ever introduced into the Elles mere district, and it was the unanimous opinion of the farmers present that this implement supplied a long felt want, by enabling those who own lands with a clay subsoil to drain off all the surface water at a very low cost. There was a good attendance of the principal farmers pre sent. The implement, as previously de scribed in our columns, consists of a strong steel blade, about 36in x 12in, which is shod at the bottom with a shoe and affixed at the top to a heavy wrought iron beam, the beam being supported in the front by a strong swivel stalk which branches out and is part of two skids. At the rear and bottom of the steel plate is (con nected with a loose link) a piece of metal about 9in long and 3in in diameter. This piece of metal, called a mole, is the all-important part of the plough. The steel blade cuts into the ground, and the shoe acts as a subsoiler by loosening the clay for about 2ft in width, then the mole drawing behind com presses the opening into a hard, solid round drain 3in in diameter, leaving it perfectly even and free from all loose soil whatever. During the trial the plough put in drains varying from loin to 24in, And should occasion require can put them in up to 30in deep. The drains were dug out in several places by the farmers present, and proved equally good and perfect in each case. Although this im plement is new to the Canterbury farmers it has been used pretty extensively both in Otago and Southland for some years, and we are informed that thirty five are now working in the Gore district alone. The implement is very cheap to work, as with twelve horses a farmer can do easily ten miles of draining per day at an ex penditure of three-half pence per chain. The plough when starting enters the ground automatically, and leaves the drain at the will of the operator by removing a key.
