COAST HUSB. 



I have examined the three different earths, 

 and tried them in acid. 



The " marl " is a white gritty chalky 

 Norfolk marl ; cfFervefcing very flrongly. 



The ' clay" is of a browner darker colour, 

 but interfperfed with fpecks of a white chalky 

 fubftance : this effervefces very confiderably, 

 but not fo violently as the marl. 



The " brick-earth " is of a dufky-white, or 

 flone-colour. It is lefs harlh than the other 

 two fpecimens ; eafily burfling between the 

 fingers to a fmooth impalpable powder ; and 

 effervefces ftrongly in acid. This did not fur- 

 prife me, as I had enquired particularly into 

 whether it was " good for the land ;" for I 

 have not yet found a clay which has been fet 

 on as a manure with fuccefs, which has not 

 been ftrongly calcareous. I had, however, con- 

 ceived that bricks could not be made from a 

 calcareous earth. But the fact is, that this 

 earth is calcareous, and that the Walfliam 

 brickmakers give 31. a load for it upon the 

 fpot, and carry it fix or feven miles, to make 

 white bricks and pavements of. 



The farmer knowing, with a degree of mo- 

 ral certainty, that his land next the fea will 

 fhoot down into it, why does he not, at once,
