 depth that it lays from the furface of the ground are various, 

 from half a foot to five or fix feet. 



The grey marl has been difcovered by a number of my 

 neighbours. Its quality is not as ftrong as the white or ihell. 

 From the obfervations that I have made, it may be found in 

 fuch funken holes as are not continually fed with hving fprings, 

 and the furrounding ground generally a clay : When that is 

 not the cafe, there is fcarcely ever any manure in fuch places 

 but black dirt. 



While I am on the fubjecl of manures, I fhall jufl obferve, 



that I conceive that farmers in general lofe a great quantity 



of their barn manure, by not having gutters to the eve of 



their barns, to keep the drop off the roof from falling into 



their yards, and by not keeping their manure covered or 



fheltered from the fnow, rain, and fun. It is my opinion, 



four loads fheltered from the weather, will be equal in flrength 



to five that has been expofed. The evacuations that falls 



from the cattle, will afford moifture fufficient to bring on a 



fermentation to rot the flraw or litter that are generally ufed 



on the like occafions.
