ON PLOWING. 



WITH DOUBLE TEAMS. 



The Committee on plowing with double teams, Re- 

 port: 



That sixteen teams were entered — thirteen of which 

 were present — engaged in the work. 



The field selected for the purpose was directly in 

 front of the building of the Theological Institution at 

 Andover. Lots Nos. 1 to 10 were 18 rods long and 

 24 1-2 feet wide — Nos. 11 to 13 were 17 rods long and 

 26 1-2 feet wide — each containing about one sixth of an 

 acre. The soil may be described as a heavy granite 

 soil, with a very hard gravelly or stony subsoil. Most 

 of the fast rocks near the surface had been removed. 

 The soil itself appears never to have been plowed more 

 than jiv2 inches deep, and the subsoil was so hard that 

 it was difficult to attain the requisite depth of seven 

 inches. Of consequence, the appearance of the furrows 

 was rougher and more broken, than it otherwise would 

 have been ; and the power required to move the plows 

 was necessarily much increased. 



The lots were drawn, and the work was done, as 

 follows — viz : 



No. 1. Jesse Curtis, of Marblehead, owner; George 

 W. Winslow, plowman; Andrew Curtis, driver. Plow 

 made by Ruggles&Co.; 2d size. Work done in 58 

 minutes, with 21 furrows; the furrows were well laid, 

 smooth, rather shallow.
