He Imay allot very fmall fields to thefe 

 experiments ; but he will neverthelefs find, 

 on many occafions, that his number of 

 labourers muft be extremely large, or his 

 trials exceedingly inaccurate. 



Hand-hoeing, horfe-hoeing, weeding, 

 tranlplanting, &c. &c. which are all much 

 pradifed in experimental agriculture, are 

 very expenfive operations, and are, never- 

 thelefs, for ever renewing, if feveral vege- 

 tables are under trial at the fame time. 



I have, in different parts of the kingdom, 

 viewed a great number of experiments, 

 and it is amazing what a number of them 

 were fuffered to be overrun with weeds. 

 This mufl either be attributed to the great- 

 nefs 'of the expcnce, or the difficulty of 

 procuring men at certain times, without 

 regularly employing them. 



The expence of keeping land clean when 

 fown or planted with any thing in rows, is 

 vaflly beyond what is commonly imagined. 

 An acre of lucerne in rows, two feet 

 equally diftant, always cofl: me from 9 s. 

 to IOJ-. hand-hoeing, each time. Hand- 

 weeding an acre of drilled corn, from 

 2s. 6d. to y s. 6d. Hand-hoeing an acre of 

 padder, from 2/. to 3/. and upwards, each 



year.
