OF FALLOWING. 24-1 



not be introduced upon soils such as above described, and 

 wherever turnips cannot be grown to advantage, fallows 

 are absolutely necessary. 



Mr Brown of Cononsyth states, that, considering the 

 short period of dry weather which is to be found in spring, 

 even on the eastern parts of Scotland, the foulness contract- 

 ed by many fields, in spite of the exertions of the most ac- 

 tive farmer, and the difficulty of rendering them clean, 

 even by a whole summer's work, any expectations of suc- 

 cess, in clearing the land during the spring alone, and 

 thereby abolishing summer-fallows, cannot be well founded ; 

 and, although summer-fallow may possibly be removed to a 

 greater distance, yet he is convinced that the process is of 

 such importance to agriculture, that it must be continued. 



Mr Spears of Dysart is also decidedly of opinion, that on 

 strong tolls, no management will turn out so advantageous, 

 as having always about one-sixth of the farm under sum- 

 mer-fallow. A heavy strong soil, he is convinced, cannot 

 be kept clean and in good order, without this system, and 

 to this he has paid particular attention, both in his own, 

 practice, and in that of others. A farmer cannot depend 

 on getting his strong soil sufficiently cleaned throughout 

 the summer, under green crops, so as to ensure a full crop 

 of wheat ; whereas, under a properly managed summer-fal- 

 low, it hardly ever fails of producing a large crop, of the 

 best quality, and, on an average, at least 13 bushels per 

 Scotch, or about 10 bushels per English acre more, than 

 when after any crop, with this great additional advantage 

 also, that of requiring little more than one-half the manure 

 that must have been used in raising wheat on any other 

 system, and also having a greater bulk of straw for being 

 again converted into manure. Besides, the land is left in 

 infinitely superior condition, and which will show itself for 

 several successive crops; the beans also, or other green
