strained tin streamers from works prejudicial to navigation ; but 

 these provisions, if not repealed, have long fallen into desuetude ; 

 nor do they seem, when in force, to have applied to copper-mining. 

 Yet, even now, the principal proprietor of mines in the adjoining 

 county requires his tenants to intercept all sand, gravel, and mud 

 escaping from their works ; * and the influence of this measure on 



been heretofore two sundry Statutes and Acts of Parliament at Westminster, 

 one in the Twenty seventh Year, the other in the Twenty third Year of our 

 King Henry the Eighth : In the which said Statutes it hath been ordained, 

 that no Person .... should labour any .... Tin- Works called Stream-Works, 

 within the County of Cormvall, nigh to any of the fresh Water Eivers there, 

 ....unless the Digger, Owner or Washer, did make sufficient Hatches or 

 Ties in the End of their Buddels and Cords, and therein put. .. .all their 

 said Stays, Gravel or Piubbel. . . .there to be wholly and surely kept, on and 

 from the fresh Water Eivers aforesaid, vipon certain Penalties mentioned. 

 To the end that the contents of the aforesaid several Statutes .... may be 

 the better hereafter performed, It is further Enacted over and besides the 

 Penalties .... already ordained .... for any Person or Persons for any Offence 



. done contrary to the Provision of the said Statutes, and that Person or 

 Persons so offending be thereof duly convicted either by Verdict of Twelve 

 Men or more, by his or their own Confession, or any other lawful Way or 

 Means, for the first offence shall. . . .incur the penalty of Forty Marks, to be 

 levied by Fieri facias of his Goods and Chattels . . . . ; and if the Party do 

 oftentimes offend, and be thereof convicted.. ..that then he is to lose all 

 such Interest and Estate as he hath in the said Works ; and if the Party or 

 Parties so offending as aforesaid, be not able to pay the Penalty of Forty 

 Marks, that then the said Party or Parties shall be committed to the Prison 

 of Lostioithiel, there to have their Imprisonment for one Year, without Bail 

 or Mainprize. And be it also furthermore Enacted, That if the Steward of 

 the said Stannary- Courts of Cormvall .... do not at each Law-Day. .. .give 



' those Statutes and Ordinances to the Jury of the same Court, that then the 

 said Steward shall for his Negligence-incur the Penalty of Five Pound at 

 each Time so offending, to be levied by Fieri facias."

 mineral- water coming from the dressing-floors or any of them before such 

 water shall fall or be permitted to flow (directly or indirectly) into the Eiver 



six several pits each not being less in dimensions than thirty feet in 



length twenty feet in breadth and four feet in depth and of such construction 

 in all respects as shall be best adapted for purifying and cleansing the said

 that purpose will take and carry out such further or other necessary and 

 reasonable means as may be required for the efficient purification of the said 

 mineral-water before the same falls or is permitted to flow into the Eiver

question in relation thereto or of the use of such means if not settled by 

 agreement between the parties to be settled by arbitration under the provision 

 hereinafter in that behalf contained."
