Plow No. Y2|-, represented by Fig. 26, lias a long, narrow mould-board, of a con- vex surface, and is specially designed for stiff soil, turning narrow furrow-slices, two- thirds as deep as they are wide. No Y2^ is adapted to turn furrow-slices 7 inches deep by 10 inches wide, in stiff clay sod, and set them at an inclination of 45°; and that is a position of furrow presenting the greatest attainable surface to the action of the atmosphere, and the greatest cubical contents of soil to the action of the cul- tivator in preparing a seed-bed. When the attempt is made to work clay sod with plows of short, wide, abruptly curved mould-boards, the furrows are too wide for their depth, and, turned abruptly, are broken in large pieces rather than disintegrated; they are laid over too flat, and in heavy clods, and a proper pulverization of the soil cannot be obtained. No. I2i, by its gentle convexity and curvature of mould- board, is calculated to work bright and free in the most adhesive soil. The plow is rigged with or without the skim coulter; though this attachment is valuable because it disposes of the grass-edge of the slice, thus preventing the growth of grass between the lapped furrows, and its use is a convenience where finished lapped work is de- sired, acting in degree like a Michigan Fig. 27. Swivel Plow, No. 83. Plow No. 83, represented by Fig. 27, is a Swivel or Hill-Side plow. Its mould- board, two in one, has the principles of construction of the other Deep Tillers. No. 83 is adapted to turn sod-slices 5 to 7 inches deep by 10 to 12 inches wide, whether the surface be hill-side or level land. A hook, fastened by a staple to the center-piece of the handles, and changing to either side of the beam as may be desired, enters the back part of the mould-board, (as may be seen in the cut,) and holds it fast on either side of the standard as wanted. The mould-board is easily and
