42 NOTES. 



dry, in any fixed period. On a new inclosure of some land in South Mimms, 

 that had been laid down to grass, after seven years' cultivation, they again ap- 

 peared in such numbers, that it was necessary to plough the land up again r 

 which would not have been necessary, had the land been pared and burnt.

534 The Marquis of Tourbilly asserts, that one-half of the seed requisite in 

 other soils, will serve on land that has been burnt, and that the crop is uniform- 

 ly a month earlier than on the adjacent lauds ; but neither of these advantages 

 has been experienced in this country.

339 Young's Calendar, p. 171. An intelligent agriculturist, (the Rev. 

 Robert Hoblyn), maintains, that the burning the roots of vegetables, to black 

 ashes, does little mischief ; but that the burning the soil to red ashes, induces 

 great future sterility. But where the staple is of an adequate depth, a por- 

 tion of the soil may be advantageously reduced to ashes by the process of 

 burning.

341 Mr Kent, in his Norfolk Report, stated his sentiments in a section, en- 

 titled, " Fallowing exploded," which was ably answered by Mr Brown, in 

 the West Riding Report, under the title of " Fallowing defended/' 



342 At what intervals the operation should be repeated, will be explained in 

 the Section " On the Rotation of Crops." 



543 The expenses of trenching, in Flanders, are calculated as follows; 1. Light 

 lands, eighteen inches deep, L.I, 6s. per acre ; 2. Strong land, eighteen inches deep, 

 L.I : 11 : 2 per acre; 5. Strong land, two feet deep, L.2, 5s. per acre. In those 

 parts of England, where men are to be found accustomed to dig, light land would 

 be trenched at 3d. per perch, or 40s. per statute acre ; and even strong land, at 

 the rate of 4d. per perch, or 50s. per acre. 



344 In the Appendix, No. VIII, there is a detailed account of the expense of fal- 

 lowing, on the improved system of the Lothians, from which it appears, that the 

 expense is greatly diminished by the use of the scarifier or grubber. In Eng- 

 land, the fallow ploughing is seldom begun so early as it ought to be, nor is cross- 

 ploughing attended to, without which the process is imperfectly done. The 

 ploughings should also be carried on in the dry seasons, being better calculated 

 for the destruction of root weeds.

355 Winter tares, unfortunately, are apt to be destroyed by hares and rab- 

 bits, being their favourite food ; and they run great risks where these vermin 

 abound.

 the superiority which winter tares, and bastard fallows, have over a naked fallow,
