330 Geological Remarks and Queries on 



Good woad, such as the richest land produces, if pro- 

 perly prepared, will be of a blackish green, and mouldy ; 

 and when small lumps are pulled asunder, the Iracture and 

 fibres are brown; and these fibres will draw apart like small 

 threads, and ihe more stringy they are, and the darker the 

 external appearance and on the green hue, the better the 

 woad ; but poor land produces it of a light-brownish green. 

 The fibres only serve to show that it has not suflfered by 

 putrefaction. 



Considerable fortunes have been acquired by the culture 

 of woad in the North of England, and those who have not 

 in possession land sufficient of proper staple, will give an 

 extra rent for leave to break pasturage; and such as is old, 

 and its sod worn out and full of ant-hills from long feeding, 

 is equally good, when lime is applied to destroy these and 

 other insects, which hero exist more than in such as is in 

 full proof to bear grass ; for here they generate and become 

 destructive, so as often to render it very necessary to plough 

 such land, corn it, and form a new turf; and though this 

 is so often prohibited, yet it is often consistent with the 

 best principles of husbandry. Here woad is every thing, 

 and corn after it to a certain degree, which experience will 

 determine, according to the kind of land. Those who grow 

 woad in large quantities, have moveable huts for their work- 

 people ; and also all their apparatus so easily put together, 

 as to be of iiule expense except in carriage. 



A friend of mine in London took a large quantity of 

 laud whereon had been wood just grubbed up. He planted 

 woad on it, and engaged a person Irom the North to manage 

 it J and the produce \Aas so abundant as to afiord immense 

 profit. I believe he only woaded two years, and then let it. 

 His tenant's produce did not by any means equal his, be- 

 cause the land began to want change. I know not how he 

 succeeds in corn, but I presume he did wellj as it is a fine 

 preparative for it.
