 land it would require a double team to work to any considerable 

 depth. 



TRENCHING. 



In the Island of Jersey, (in the English Channel,) which has 

 always been noted for its great fertility, — and especially for the 

 large parsnips there grown, which are extensively used in cattle- 

 feeding, and which require a very deep soil, — there has been used 

 for a hundred years what is known as the Great Jersey Trench 

 Plow, which, drawn by six or eight horses, turns the soil to a depth 

 of from one and a half to two feet, the surface soil and the manure 

 being first turned into the bottom of the deep furrow by an ordi- 

 nary plow drawn by two horses. Neighbors "join teams " for the 

 operation, which is called " The Great Digging." 



Dr. Grant, of lona Island, on the Hudson River, near Peeks- 

 kill, N. Y., has nearly perfected an invention, which — judging 

 from the drawings — is better adapted to a work of this kind than 

 is the Jersey plow. It is thus described in Judd's Agricultural 

 Annual for 1868 : —
