The narrow Strata of the brick-colored earth or clay 

 tegelfargade jorden eller leran went sometimes in 

 long curves, tmkter, upwards, sometimes downwards. 

 It was remarkable that the lowest stratum of all, or 

 No. 8, was Hurlock wherein there was scarcely a single 

 flint, fliutsten, which however were tolerably abundant 

 among the chalkbeds. [T. I. p. 347. J The carl who 

 accompanied us said that Hurlock is the best to burn lime 

 of, and that such good lime does not come from pure 

 and loose chalk. Some of the flints in the chalk 

 resemble spigots or goats horns. Might I not have got 

 to see freestone underneath this, such as there was at 

 Tattemel if the pit had been some fathoms deeper ?* 



* This question may be answered definitely. The bed (No. 8) here so 

 well described by Kalm, as to make it easily recognisable, is the top of the 

 "Chalk Rock" beds of Mr. W. Whitaker, which lie at the base of the 

 Upper Chalk and on the top of the Middle Chalk, to which as a whole I have 

 repeatedly heard the name of " Hurlock " applied on the area between Trim; 

 and Dunstable. 



The thickness from the " Chalk-rock " of Whitaker to the freestone of 



Tattemel or Totternhoe is 310 feet.
