WHAT TO USE FOR WATER-PIPES. 147 



ever, in securing the sections free from minute 

 orifices which render them leaky, and also it is 

 troublesome to form tight joints. When made of 

 extra thickness, and put in position with care, the 

 clay pipe of small calibre may conduct water under 

 a moderate head, for many years, with great satis- 

 faction. That which passes through will of course 

 be as pure as the mountain or meadow stream at 

 its source, and this is a point of the first importance. 



A CARBON WATER-PIPE, 



so called, was manufactured and introduced some 

 years since, but we have learned but little regard- 

 ing its success. It was made, we think, of asphalt 

 and sand principally, and had the merit, at least, 

 of indestructibility. The difficulty and cost of con- 

 struction may perhaps have proved obstacles in 

 the way of its production ; and so it has disap- 

 peared from the market. In addition to the vari- 

 eties of water-pipe described, we may name the 

 glass and the porcelain-lined iron pipes as worthy 

 of notice. Iron pipe has been successfully lined 

 with glass, and we believe the cost was not so 

 great as to prove a bar to its general employment. 

 Nothing could be constructed sweeter and cleaner 

 than pipe of this nature ; and we regret to learn 

 that its manufacture has been abandoned in this 

 city. We venture to hope that some one will
