74 Observations on Ploughing, Sc.[Aug-
Tt is greatly to be wished that a breed of horses Suitable for the plough and the team, was encouraged witbin the circle of the Manchester Society; of moderate Size, and in form and Strength, like the farmers' horses in Norfolk and Suffolk, or the Stallions of Mr. Summerland, of Uitozeter.
In the construction of ploughs great improvements have been made, and these implements are as various, as the pur- poses for which they are intended, and the Situation and na- ture of the country in which they are employed. In general they are all made on a much lighter construction than for- merly.;

He observes on the quantity of work done in a day, that in calculating it, great attention Should be paid to the thickness of the furrow Slice, and the quickness of the horses Step.
He states that, in his country, the usval breadth of the furrow Slice, is from nine to ten inches, and from five to Six inches deep.
Mr. Erskine, then caleulates the number of yards that a plough team travels, in ploughing a given quantity of ground, according to the variations in the furrow slice« For ex- ample--
