fore in haft I proceed to a more particular Confideration of Earths 
(as before of ^F^/er^) holding fome Spirit^ Bitumen^ or concrete 
Juice , and as they are ufeful in Trades^ or are otherwife neceffary, 
convenient, or ornamental. 
7. But herein I (liall not fliew my felf either fo angry or igno- 
rant, or fo much either difrefpedt my fubjeft, or the civilities of 
the Gentry for the fake of the clowns^ as not in the next place to 
treat of fuch Earths whofe moft eminent ufes relate to Hwsbandry^ 
fince they alfo hold fome concrete Juices (whereby they become 
improvements of fuch poor barren Lands) and are therefore 
very fuitable to my prefent purpofe. 
8. The beft of thefe we call commonly il/^3'r/i",whereof,though 
'twas believed there were none in Oxford-fiire^ yet I met with no 
lefs than three feveral forts, and in quantities fufficient enough 
for ufe. The Britifi Marls w^re very famous of old, whereof 
Fliny'^ numbers feveral forts ; and of principal note were the 
LeucargilU , whereby, he fays, Britan was greatly enriched : 
And of this kind, that I guefs may be one, lately difcovered by 
the much Honored^ and my truly noble Friend, Thomas Stonor Efq; 
of IFatiington-Park-, of which he already has had good expe- 
rience : of colour it is whitijh^ a little inclining to yellow^ not 
very fat, and of fo eafie diffolution, that it may be laid on 
the ground at any time of the year, and may be as good, I fup- 
pofe, for pafture as arable : this he found at a place near Blunds- 
Court^ but I think within the Parifli of Shiplah-, where upon an- 
other account fmking a deep pit, amongft other matters he met 
with this MarL 
9. Since that, there has lately been another difcovered by that 
eminent Virtuofo Sir Thomas Fennyfton^ in his own Grounds in the 
Parifli of Cornmll^ about a quarter of a mile north-weft of his 
Houfe, of a blue colour, and fo abfterfive, that it would readily 
enough take fpots out of cloaths, and gave its owner fome ground 
to hope, that pofTibly it might be fit for the Fullers ufe ; but he 
quickly, upon tryal, difcovered an incurable fault that the Men 
of that Trade will never pardon : however, I take it to be fo 
rich a Marl^ that it may amply recompence the induftry of its 
Mafter^ if laid on its neighboring barren Hills; which I advife 
may be done about the beginning of Winter, that the Frofts and
