Several Attempts have been made to run Iron Ore 
with Pit-coal j I imagine it hath not fucceeded any- 
where, becaufe we have had no Account of its being 
pra&iled ; but I find that Mr. Ford , from Iron Ore 
and Coal, both got in the fame Dale, makes Iron 
brittle or tough, as he pleafes 5 there being Cannon

At Brofeley , about a Mile from the fore-mention'd 
Place, in the Year 1711, was a Well found, which 
burned with great Violence, whereof feme Account 
is given in ‘Philo f. Tranfalf. N°. 3 34? but it has 
been many Years loft. The poor Man, in whofe 
Land it was, miffing the Profit he ufed to have by 
(hewing it, applied his utmoft Endeavours to recover 
it 5 but all in vain, till May iaft ; when, attending, 
to a rumbling Noife under the Ground, like what 
the former Well made, tho’ in a lower Situation, 
and about 30 Yards nearer to the River, he happen'd 
to hit upon it again. 
That you may have feme Notion of what it is, 
I will lay before you fuch an Account of it, as the 
curfory View I had will permit. 
The Well for 4 or 5 Feet deep is 6 or 7 Feet 
wide s within that is another lefsHole, of like Depth, 
dug in the Clay; in the Bottom whereof is placed a 
cy lindric earthen Veffel, of about 4 or 5 Inches Di* 
ameter at the Mouth, having the Bottom taken off, 
and the-Sidcs well-fix cl in the Clay 1 a min’d ciofe about 
it.
