54. The Natural Hijlory 



Rain may the better feparate its parts, and fit it to incorporate 

 with that hungry Soil. 



10. Which condition I fuppofe may not at all be required, in 

 the manure of a light and hollow fort of Marl., lately found by 

 the worfhipful and induftrious Improver, George Pudfey Efq; of 

 Elsfield: for in water it diffolves almoft as foon as Fullers earthy 

 and is naturally of it felf fo hollow and fpungy, that one would 

 think it were always in the very ferment, and may therefore be 

 ufed at any fit time of year : of colour when dry, it is of a 

 whitifh gray, intermixed with fand, and very friable, and may 

 in all probability be the very fame, with the Marga Candida are- 

 nofa friabilk, of Hildejbeim, mention 'd by Kentmannus s , and out 

 of him by Lachmund. Of juft fuch another Marl as this, brittle 

 and dufty when dry, but fat when wet, we are inform'd there is 

 at Wexford in the Kingdom of Ireland, by D r GerrardBoat l fom- 

 time Phyfitian there ; only thzt that is blue, and this a vvhitidi 

 gray, and may therefore be fitter for Pafture than Arable. It 

 being obferved in the Counties of Sujfex and Kent, where Marls 

 are molt plenty of any places of England, that the gray fuit with 

 Paftures,andthe/e (fuch perhaps as Sir Thomas Penny/Ions') with 

 Arable belt. 



ii. It may therefore be expedient, that thefe new found 

 Marlsbe thus agreeably tryed, and though they anfwer notexpe^ 

 ftation the firft year, as fome fay they will not % let not their 

 Owners be thus difcouraged, but ftill continue to make frequent 

 tryals, of divers proportions of Earth, at all feafons of the 

 year, with all kinds of Grain upon all forts of Soil, till they 

 find out the moft fuitable and neceffary circumftances, fo iliall 

 they in time attain to a knowledge beyond the expectation, and 

 perchance imitation of their Neighbors. But I forbear to in- 

 ftruct fuch Ingenious Perfons, as the Owners of the above- 

 named Marl-pits are : the Orator being accounted little lefs than 

 a fool, that went about in his Speech to teach Hannibal to 

 fight. 



12. But befide thefe, we have another fort of Earth, of a fat 

 clofe texture,and greenilli colour, fo well impregnated with fome 

 kind of fait, that put in the fire, it prefently decrepitates with no
