The plan of the field given above will further show the method of manuring 

 adopted in 1845. In the two previous years each experiment extended from one end 

 of the field to the other; in 1815, 72 yards down the field was sown by hand across 

 the rows respectively witli rape-cake, equal to 10 cwt. per acre; 10 cwt. rape-cake and 

 3 cwt. sulphate of ammonia; 3 cwt. of sul[)hate of ammonia: the manures given as 

 drilled manures were then drilled down the entire length of the field. Thus, from 3 

 to 24 inclusive, each space of land which was on experiment in 1843 and 1844 

 was, in 1845, divided into 4. The figures represent the same spaces of land each 

 year. For example, No. 2 was unmanured in 1843 and 1844; in 1845 one part was 

 unmanured, one was crossed with rape cake, one with rape-cake and ammoniacal salt, 

 and one with ammoniacal salt. The plan adopted in 1845 has been continued in 

 1845 and 1847.
