That several since theour lastte Report Assays have been made in the Tower of Parcels of Tin chosen by cut off from blocks in Cornwall by her MajtsMajesties Assr of Tin West East country Tin melted by in the furnaces & in the blowing houses & both sorts found of like goodness without any manifest difference

That Assays have been made also of pieces cut of from blocks by yethe by the Agent of yethe Patentees & the Tin proved of like goodnes wthwith yethe former.

That none of these Assays pieces proved grain Tin ithey beting West East country Tin where very little grain Tin is produced.

That some represent above one tenth of all yethe grain Tin in Cornwal has heretofore been grain Tin & others that not above a 20th part And that yethe Agents in Cornwasll be directed to give the best acctaccount they can of what number of bocks of grain in hasve been p made by the Patentees in the th last coynages commen & yethe prent in proportion to the other sorts of Tin.

That some represent that the staying of Tin in fusion in the furnaces longer then in yethe blowing houses consumes the best parts of the Tin, others that it consumes the drossy parts & makes refines the Tin. And for the discision of this point We humbly desire that the Agents in Cornwall a triall may be made in CorwalCornwal before yethe Queens Assr & the Agents or whom they think fitt to roder, whether the Melting houses or the blowing houses by their usual ways of working do p out of the same parcel of washt Oar called black Tin O can d produce the best Tin & whether Tin by being kept some hours in the heat of the furnaces grow better or worse then at first & a report thereof be made to yrhis LordpLordship. For we have ne For such trials can be only made upon the place

We humbly beg leave to represent to yoryour LordpLordship that Daniel Stuart the Collector of the Bullion for the Mint at Edinburgh is thereby deasd (as we hear by the last Post) & that in orour humble opinion the place of Collector of the Bullion being irregu irregular & useless should cease & the said Bullion be hence forth paid by the under Collectors into the hands of the Cashk Exche hands of the Cashkeeper of the North Br Britain & kept apart in the Exchequer in a proper Chest under the key of the said Cashkeeper & also, if it be thought fit, under the key of the General of her MatiesMajesties said Mint, (as is directed by the Scotch Act of Parliament directs for setli granting this Duty to the Mint) directs,) & he in order to be in order to its being & that it; to be issued out thence from time to time to by Warrants to the General & Master of the said Mint & to be & kept apart in the Treasury of the said Mint under the keys of the General the Master & the Wardens for defraying the charges of paym coynage & repairs & paying of Salaries & be accounted for annually by the Master [according to the rules set down in the Indenture of her MatiesMajesties Mints,] the Act of Vnion so that the two Mints may be under all the same Rules, in all respects as in full conformity to the Act of Vnion. And we are further of of Opinion that the Executor or Executors of Executors of the said Mr Stuart be speedily called to account speedily called to account & & directed forthwith to pay into yethe hands of the General Master of that Mint the summ of such a summ of money as yoryour LordpLordship shall think fit, suppose the summ of 25500 or 2500 pounds, to be kept in the Treasury of that Mint under the keys of the General the Master & Wardens, that the service of that Mint receive no stop for want of moneys, there being as we are very credibly informed, a far greater summ in the hands of the said Executor of said Mr Stuart All which &c.
