The produce on the three unmanured plots varied to some 

 extent, as did also that on the two plots which received rotten 

 dung-. The greatest variation in the unmanured plots amounts 

 to 10 cwts. 2 qrs. and 14 lbs., and to 6 cwts. 1 qr. in the dunged 

 plot, as will be more clearly seen in the following table: —
