110 On Strarv Cutting and Mangel WurtzeL 



giving the data for calculation, I discovered that the to- 

 tal amount of btrets raised on the thirty one and three 

 quarter square poles of ground, as above specified, would 

 be equivalent to the rate of about nine hundred bushels 

 of carrots per acre. Jn addition to this superiority of the 

 beet, wh-ch respects the quantum of the roots of the two 

 pla \ts only, is to be taken into the account, the value of 

 the beet leaves, as also the culture of the latter, which, in 

 tht way I planted them, requires less manual labour; the 

 vacancy between the rows being sufficiently great for the 

 admission of a plough with one horse ; whereas the carrots, 

 after they are above ground, require the use of the hoe and 

 hand weeding altogether. I have therefore concluded to 

 turn my attention more particularly to the culture of the 

 beet, in preference to the carrot. 



Thou observes it would be gratifying to have my per- 

 mission to lay the details and results of my practical expe- 

 rience before the Agricultural Society. I have only to re- 

 mark, that if any of the above is considered of sufficient 

 interest to claim the attention of that highly respectable bo- 

 dy, I shall not object. 



Thine with sentiments 



Of much respect and esteem,
