they are the beft, and moft efteemed j but they coft; more by 

 realon of their Weight. Solder'd-Pipes are no other than 

 Pieces of Sheet-Lead turned up, and folder'd at the Joint." 

 The biggeft leaden Pipes rarely exceed fix Inches diameter^ - 

 and are fixed one to another with Joints of Solder. They 

 are fubjea; to burft, and to wafte in Ground that is full of 

 Chalk. 



Pipes of Earth, or Potter's-Clay, which was the third 

 Way of carrying Water among the Ancients, is that whic^ 

 cofts leaft, but requires the moft Repair. Thefe Pipes are a. 

 Compofition of burnt Earth, like that of which Pots an4. 

 Pans are made. The feveral Lengths, which are generally 

 two or three Foot long, run one into another ; and the 

 Joint, which is made with a Hera, or Collar, is fecured 

 with Maftick and Hemp. When thefe Pipes are made ufe 

 of tp convey Water that is forced, they are environ 'd witfe 

 a folid Body of Ciment five or fix Inches thick, which pre^ 

 ferves them fome Tin;e, provided you firft take the Precau- 

 tion, to let the Conduit dry fome Months before you lay 

 the Water into it, that the Mortar may have Time to har- 

 den ; and, fecondly, to fecure the Pipes, which are very Architeaure 

 brittle, upon folid Beds and Foundations of Mafonry, for F^ncoife de 

 fear they fink with the Weight. Thefe Pipes are more pro- xxx?p?tS. 

 per to carry off the wafte Water of Bafons, than that which 

 is to fpout aloft, which they can hardly refill: any long 

 Time. They are fubjea to Fox-Tails, which are the 

 Roots of very fmall Trees, which paffing by the Pores of 

 the Earthen Pipe, or by the Joints of Maftick that rot in the 

 Ground, live in the Water, and grow to fuch Length and 

 Bignefs, as to flop up the Pipe entirely. I have found fome 

 of them five or fix Fathom long. Some will have it, that 

 thefe Fox-Tails come from the Hemp that is wrapt about 

 the Joints of Maftick, or elfe from certain Seeds that enter 

 the Conduit with the Water. 



Earthen Pipes have a peculiar Excellence, for Foun- 

 tains of Drinking-Water, That being glazed on the Infide, 

 no mud or Slime fticks to them, and the Water keeps better 

 and freflier than in other Pipes befides that, it gets no ill
