fo much — or my total expcnce and profit will fland thus, &c. But 

 mix all thcfe kinds of plantations, and the difTcrent trees fuitable for 

 each kind topjether, as is commonly done, and what can be faid about 

 Uiem ? or to wliat advantage can they be turned ? The proprie- 

 tor mud feel great diiliculty in diredling their general management, 

 and great uncertainty as to wliat they Ihould prcKiuce ; nor has he 

 any kind of check upon either the manager, tiie buyer, or the fel- 

 ler of his timber. But, by the mode which I recommend, he ha* 

 a certain object in view in every plantation, even in every hedge- 

 row or fmgle tree ; and all his operations tend to promote thi;^ 

 objecfl:. In this way he operates, though not with an abfolute 

 certainty of the profits and lofs, yet with fuch clear ideas on thefe 

 heads, that lie can never be at a lofs how to proceed, nor even 

 greatly difhppointed in his expec'lations. J. L. L. & J. 



P. S. — In the laft Number of your Magazine, a correfpondent 

 requefts information ' concerning the molt expeditious way of 

 taking up the roots of trees. ' 1 only beg to ftate, in cafe you 

 fliould not be favoured with a more complete anfwer, that the 

 bed machine that has been ufed hitherto for this purpofe in Eng- 

 land, where oak roots of immenfe fize arc extracted, is the Eradi- 

 catovy a defcription and drawing of which, and alfo of another 

 machine of the fame kind, called the German Devil, will be found 

 in the laft edition of Shenton's Euclyiis Sy/va. 



I think, that if the cyUnder in thefe machines, on which the 

 rope is wound up, were made conical, fay i foot diameter at one 

 end, and 4 feet at the other, and the rope put twice round at the 

 fmall end, one man alone would with eafe raife the largeft ftone. 

 Or tear up the largeft root that the ftrength of the machine could 

 bear. But fince I thought of this plan, I have not had time to 

 try the experiment, and therefore ftiall fay nothing furtlier at pre- 

 fent.

Account of Far7ner Crefinus and his Enchantments, 

 Sir, 



While you beftow fuch laudable attention 6n the important 

 fcience of agriculture, and very properly confider every fatt and 

 circumftance connected with it as worthy of your notice, I am 

 furprifcd that one clafs of caufes, which were confidered by moft 

 people formerly, and by many ftill, to have a confiderable influ- 

 ence on the fuccefs of the hufbandman's operations, feems hi- 

 therto, as far as I can recolleiSl:, to have efcaped you altogether. 

 I hope, therefore, you will take in good part this attempt to fup- 

 ply the omiflion.

importance
