Letter – Isaac Hunter to John Erasmus Blackett – 21 May 1780

J.E. Blackett Esqr  N.Castle 				Dukesf[iel]d 21st May 1780



Sir

You'll receive herewith a Plate of Silver as per inclosed acco't I understand by Mr Mulcaster that you wanted to know what quantity of Com[m]on & Reduced Lead we can deliver f[ro]m the Several Mills before the latter end of Aug[us]t if we are kept going with Com[m]on Ore till then (w[hi]ch I have no doubt but we shall at this Mill) shall be able to send to Blaydon f[ro]m this Mill 15500 p[iece]s Com[m]on Lead and 8500 p[iece]s of Reduced Lead f[ro]m Allanheads 2000 f[ro]m Rookhope 6000 p[iece]s but as the Com[m]on Ore is always late of the season of geting to Rookhope so that I think you must not call the quantity f[ro]m that Mill more than 4000 p[iece]s to be at Blaydon before the time mentioned but the Dukesf[iel]d & Allanheads you may make your self sure to have at Blaydon against the time mentioned as I have seen Mr Forster & he says they will keep the Smelters going w[it]h Ore 

I am Yrs &c IH
