After they had pounded a heap of chalk fragments 

 into smaller bits, all the pounded chalk was not carried 

 to the limekiln, but they laid it first in a coarse ' fiddle ' 

 and screened away that which had gone to powder, which 

 they did not take. The flints which were found in the 

 chalk were separated therefrom, and were cast together 

 in a heap, to reform the ground, as they were obliged to 

 do. The limekilns were here built entirely underground, 

 so that the upper edge of the limekilns was horizontal 

 with the surface of the ground.' The kilns were, however, 

 here one-third part smaller than those which are at North- 

 fleet, and getting on for half the size ; but in other respects 

 nearly of the same form, excepting that at the bottom 

 there is only one draught-hole, drag-hal, instead of 

 several as in those at Northfleet. They also went through 

 at once down to. the same draw-hole, like a tar-mill with 

 us in Osterbotten. In other respects, the walls are all 

 built of brick. The Carl said that the chalk, which he 

 lays in the kiln the one morning, can be ready burnt to 

 take out the following morning. The lime they burn here 

 is not carried to London, but is all used up at Rochester 

 and in that neighbourhood. 



The chalk is burned, in other respects, here in exactly 

 the same manner as at Northfleet, viz., alternations of coal 

 broken into very small pieces, and bits of chalk, etc.

[T. II. p. 9 1. J Sain Foin is much used here in Kent. 

 Most people here call it Cinque/oil which they have cor- 

 rupted from Sain Foin. When it is once sown, it can 

 stand ten or twelve years, without requiring to be sown 

 again ; for which time they can mow it every year. After 

 the time when it begins to be somewhat thin, so that it 

 does not seem to be worth while to mow it, they do not 

 at once. plough up the ground it grows upon, but let it.
