light on the policy that was pursued in regard to the indus- a of
irial development of the plantations.
The paucity of fuel had caused anxiety even in Tudor
times, and there had been legislation with the view of main-
taining woods and coppices in the reign of Henry VIIL®
The Sussex Ironworks were regarded with special suspicion, which,

as they drew on supplies of timber that might have been migration
available for shipbuilding and competed with London for of iy
supplies of fuel. Eventually they were starved out; and the Buses
iron-trade migrated to Shropshire and the Forest of Dean,
where both iron-ore, and fuel for smelting, were more easily
obtained. It was obvious, however, that, though this was
a temporary relief, it could not prove a permanent remedy.
From the sixteenth century onwards, attention had been gud Ling

erected in 1779, marks the beginning of an iron age, when

the Bedfordshire Quarter Sessions Records in the seventeenth century. Compare

“There is one man, whose dwellinge place is within twenty miles of the cittye of
Durhame, which hath brought to the grounde, above 30,000 oakes in his life tyme;
and (if hee live longe) it is to be doubted, that hee will not leave so much tymber
or other woode in this whole County as will repaire one of our churches, if it
should fall, his iron and leade workes do so fast consume the same.” A. L.,

3 The most important steps in progress may be briefly indicated. Abraham
Darby succeeded in 1735 in making coke from coal; this served as a substitute for
wood charcoal in the furnaces for smelting the ore, when a more powerful blast
was used (Smiles, Industrial Biography, p. 338). In 1766 the Cranages introduced
a reverberatorv furnace in which coal could be used, and superseded the forges in
