Mr. Wilkinson, of the Mt. Airy Agricultural Institute, has lately read an interesting paper before the Philadelphia agricultural association on ploughs and tillage. He exhibited a plan of a horticultural plough, which appears to us worthy of attention, and accompanied it with the following remarks:
To perfect the catalogue of ploughs for the various purposes, we need a plough which might properly be styled the Horticultural Plough, for the purpose of ploughing in orchards; one that will enable us to till close to the trees without exposing them to injury from being barked or galled by the Whipple-trees of the horse tackling, or the yoke of the oxen; and also to guard against injuring the teams, which often occurs in ploughing among trees, by bruising their hips against them. The same instrument, if properly constructed, will also be found very useful for ploughing along fences, whether the furrow is to be turned to or from the fence.
I have prepared a diagram of a form of plough, which I will submit to your inspection, that will be found an efficient improvement for all the above purposes, for which no manufacturer has ever succeeded in making one in the least adapted. In tilling the land near the thorn, or maclura hedge, this plough will enable us to till as close to them as we desire, without subjecting the teams to that painful laceration by the thorns, which is unavoidable in the use of a common plough in tillage. Any common plough, that is adapted to both fallow and sward land, and one that is considerably worn, will answer the purpose for a horticultural plough, when altered, by attaching to it the shifting beam - from the fact that it will be used but little, compared with other ploughs; hence a plough considerably worn, will answer as well as any.
