One hundred grains of the Maltom 

 GRANATE, taken from the middle of the 

 quarry oppofite the Lodge at New-Malton, 

 yield forty-four grains of air, and ninety- 

 fcven grains of calcareous earth, leaving three 

 grains of rcfiduum, chiefly a brown lilt. 



But the ftones of different quarries vary 



in quality. One hundred grains taken from 



a newly-opened quarry, by the fide of the 



road leading from Malton to Caflle-Howard, 



yield only ninety-four grains of diffoluble 



matter.

* On this fide of the Vale, too, the llmeftone rubble 

 which lies between the foil and the rock, is much of it 

 of the nature of mar l, and might in many cafes be ap- 

 plied as fuch with advantage.' Its efteft, where it has 

 been thrown back from the edges of the quarries on 

 Scallow-moor (a light loam inclining to a black moory 

 foil) above Pickering, is ftriking. The earth of this 

 rubble is itrongly calcareo'.is, and its flones are fre- 

 quently covered with a white efflorefcence which is 

 purely calcareous. Great quantities of it might be 

 Gollc(5ted ; and where a fit foil can be found (by trying; 

 experiments with it on a fmall fcalc) in the neighbour- 

 hood of a quariy, it would in all probability pay amply 

 for fetting on. For the bottoming of farm-y-irds and 

 dunghills, the entire '* coping," the foil inclufivc, 

 would be found c:;ccllcnt.
