likewife a letter upon the fubjeCt addrefTed to the So- 
ciety for encouraging of arts and manufactures, by 
one Mr. G. Elliott, who relates, that, though previous 
to his attempt of making iron from this fand, he met 
with nothing but what was difcouraging from the 
mod: fkillful perfons to whom he propofed his defign, 
yet that he had fuch a perfuafion in his own mind of 
the practicability of the thing, that he could not red 
till he had made a trial, and the event proved encou- 
raging much beyond his expectations, infomuch 
that he could fcarcely believe the trial had been fairly 
made, till a fecond trial evinced with certainty, that 
eighty three pounds of the fand would produce a barr 
of excellent iron weighing fifty pounds : a prodigious, 
yield indeed, and far beyond what I have ever heard 
of from the riched common ores that are any where 
to be found ; mod of the ores I have ever met with 
or heard of, yield little more than half in pig metal, 
and which will differ a wade of near 7 part to make 
tolerable good barr iron, and much more if I am 
rightly informed, when the iron is intended for 
more valuable purpofes, fuch as being drawn into 
wire, &c. 
After I had feen his addrefs in his letter to the So- 
ciety, and his pamphlet j by the aflidanceof my friend 
Mr. Collinfon, I fent him over two or three hints, 
which I judged might be of fome fervice to him 5 
this produced the favour of a letter from him, of 
which the following is an exaCt copy. 
Mr,
