186 THE MINERS FRIEND. 



you shall please to pass upon me or the Invention, and may 

 have reason to believe you will not any longer suffer your 

 Judgments to be imposed on by those, whose Profit and 

 Interest it may seem to be, to Condemn both right or wrong ; 

 I mean such who make your common Ginns, and their 

 Friends and Acquaintance among you ; tho' I am very sure 

 the promotion of the Use of this Engine is their true Interest, 

 as I very plainly prove thus : 



The cheaper Water is drawn, the more is the Miner 

 incouraged to adventure ; the more the Miner adventures, 

 the more Pits or Shafts muft be sunk ; the more Shafts or 

 Pits are sunk, the more Wood-ivorh will be necessarily 

 imployed in Timhering them, or supporting the sides from 

 falling in where the Earth is loose ; besides Windelesses and 

 all other Utensils of Wood iised in Mines, or the Trades 

 depending thereon must be more, which by inci^easing the 

 Carpenters Trade in general, will make them sufficient amends 

 for the loss of a small part of that Branch of their Trade, 

 called Ginn-making. As for Pump-maMng , that part of the 

 Trade will be much Improved by my Engine. For I must 

 use Board and Timber for Pipes; and have considerable 

 Imployment for Pump-makers and Carpenters for Timber 

 used about my Engine. But shall never Imploy any other 

 Person in making Pipes, or any other Carpenters work I 

 shall have to do, but the Person who was before imployed in 

 the Work, or such as shall be recommended, as a Person 

 imployed in the Mines of the Country wheresoever I shall fix 

 Engines ; provided they will work as cheap, and fairly, and 

 observe the Orders and Directions given them. For my 

 Design is not in the least to prejudice the Artificers, or indeed 

 any other sort of People, by this Invention ; but on the 

 contrary, is intended for the Benefit and Advantage of Man- 

 kind in general, especially the People of my own Nation ; and 

 wherein, you Gentlemen concern' d in Mines, may, if you 

 please. Reap the greatest Profit. 



And altho' I do not question but the Plan, and Draught of 

 my Engine, will be very well and readily understood with 

 many Gentlemen, by the Description here given ; yet it will 

 require a longer Time in Others, to imploy their Minds and
