in. An Account of the Manner of Manuring Lands 
hy Sea-Jhellsy as praBifed in the Counties of Lon- 
donderry and Donegall in Ireland. 1% his Grace

Samuel Molyneux 
B oth there Counties are very mountainous, and thofe 
Mountains covered with Boggs and Heath, in fo 
much that there is little Arable Ground in them, except 
what has lately been made fo. There are three ways 
pradis’d to reduce Heath and Bog to Arable Land : The 
firft is by cutting of the Scurf of the Ground, making up 
the Turf fo cut in heaps, and when the Sun has dryed 
thete Heaps, they are then fet on Fire ^ when burnt as 
much as they can be, then thofe heaps are fcattered on 
the Ground, and it being Plowed, it beareth Barley, Rye, 
or Oats, for about three Years. 
The Inconveniences are firft, that fuch Burning defiles 
the Air, caufeth Rain and Wind, is not pradicalin a wet 
Summer 5 and by deftroying the Sap of the Earth and 
Roots of the Grafs, and all other Vegetables, renders it 
ufelefs for feveral Years after the third, in which it is 
Plowed. 
The fecond way is by Liming 5 this is much better than 
the former, becaufe it doth not fo much Depauperate 
the Ground, will laft long, and beareth better Grain, and 
whatever is pretended, doth not deftroy the Grafs, if due 
care be taken not to over Plow it 5 but then this is very 
dear, and Lime-ftone is not every where to be had, and 
in many Places Fire is wanting.
