82 Remarks on Rotations. 



unusual disposition to produce annual weeds, such as the corn mary- 

 gold, &c- these are certain indications, that the cultivated soil is 

 deficient in a due proportion of lime. The subsoil dressing is usually 

 laid upon wheat stubble, in preparation for turnips ; also, upon two 

 years' layers, in preparation for wheat, and sometimes upon young 

 clovers, immediately after the barley is carried off, and the harvest is 

 over.

THE following communication was drawn up for this work, by Mr 

 George Sinclair, author of that most important publication, the " Hor- 

 " tus Gramineus Woburnensis" At the desire, and under the pa- 

 tronage of an illustrious friend to agriculture, John Duke of Bedford, 

 he had carried on at Woburn, for several years, a number of experi- 

 ments, to ascertain the most profitable means of promoting the improve- 

 ment of permanent pastures, of irrigated meadows, of dry and up- 

 land pastures, and of the alternate husbandry in general. The result 

 of those experiments is contained in the work above mentioned, by 

 the dissemination of which, an immense addition will be made to the 

 agricultural resources of the empire, and the management of grass land, 

 will be brought to a degree of perfection, of which hitherto it had not 

 been considered susceptible. 



The objects of this paper are, to point out, 1. The plants which con- 

 stitute the produce of pastures on different soils ; 2. The natural ha- 

 bits and comparative value of these plants ; and, 3. The mode of cul- 

 ture to be pursued, in returning land to permanent pasture, of the best 

 quality, after having been cultivated.
