tance to preferve thefeveral'Bafons I have been fpeaking of: 

 For^ if in a Bafon of Clay the Water be not high enough^ 

 the Body of Clay that compaffes it will dry and chap, 

 and the Water will be loft ^ for which Reafon likewife it 

 is^ that all round, upon the Walls and Clay-work, you 

 lay a Border of Grafs of the fame Breadth, that the Siin 

 may not fo eafily attrad and draw away the Moifture. If 

 it be a Bafon of Ciment, the Plaiftering of the Sides will 

 be liable to be fpoilcd by the Froft, and to peel off; if it 

 be a leaden Bafon, the Sun will be apt to blifter it, and 

 open the foldered Joints ; for Lead is hurt more by the Heat 

 than by Froft, and the Water will then be loft, which is no 

 eafy thing to remedy. 



For the Wafte-Pipcs of Bafons, whether at Bottom, or 

 upon the Superficies, you ftiould obferve to make them ra- 

 ther large than fmall, being very fubjcft to bechoaked, not- 

 withftanding the Cawls that are put before them. This 

 Wafte-Water is carried away in Drains, or Earthen-Pipes, 

 when 'tis only to be loft in Sinks and Common-Siiores ^ 

 but when it ferves to play the Bafons that lie below^ you. 

 muft then make ufe of the ordinary Leaden-Pipes. 



These large Difcharges, befides that they ferve ta. 

 keep the Walk about a Bafon dry and in good Order, are 

 alfo very neceffary to the Prefcrvation of a Bafojn : For 

 when the Water runs over at any time, it dilutes the firm 

 Ground upon which the Area and Foundations of the Ba- 

 fon are fet, and fpoiis the Level of it. 



Of the three ways of making Bafons, which I have beefir 

 fpeaking of, that which cofts leaft is doubtlefs the Clay, to 

 which you muft have recourfe in great Water^works, for 

 faving Expence. But it is that too, which requires moft, 

 looking after of all, being very fubjeit to dry and chap, 

 which w^U obhge you to run it over again from time to 

 time That which cofts moft, is the Bafon of Lead, becaufe . 

 of its Weight and Solder i and the third, which is tiut of 

 Ciment, is preferable to all for its Duration, and may be 

 faid to keep a Medium, as to the Charge between a Bafoa . 

 of Clay and one of Lead : There is nothing but the Plai- 

 ftering of them can ever be fpoikdi tliis is To true^ that I,
