ground after every fliower, and the natural 

 ilony, or gravelly bottom, becomes, by 

 being trod by cattle and foftened by wet, 

 an impenetrable cement, and holds water 

 extremely well. I have made fome ponds 

 of this kind, which I believe will anfwer 

 perfectly. If a large fupply of clear water 

 fhould be required in a very high fituation, 

 1 imagine an engine might be contrived, 

 fo as to pump a copiaus ftream, by means 

 of fails turned by the wind : Water may 

 certainly be raifed by horfes from the 

 dcepeft wells. As to wood for fuel and 

 fencing, true it is, that this country does 

 not at prefent furnifh it ; but it is no lefs 

 true, that it is capable of furnilhing enough 

 for every oeconomical purpofe: The liedges, 

 and hedge-row trees round every village, 

 are a proof that the foil is not improper for 

 wood ; and fome very thriving plantations 

 on the tops of the hills, which a few 

 gentlemen liaA'^e had courage to raife, wilt 

 be a lading monument to their praife, as 

 well as an example for others to imitate. 

 Though the Scotch fir has been ufually 

 feleOcd for thcfe trials, and has fucceeded, 

 yet the afli will do as well, and is a much 

 more valuable tree : For ploughs, fellies of 

 wheels and axles, for fliecp bars, and for 

 The coopers ufe, no tree is equal to it ; it is 

 bcfides a very quick grower, and fprings 



admirably
