THE MANUFACTURE OF MONIER PIPES. XXXVII. 



The pipes are made in convenient lengths, from 1' 9" to 5' 0" 

 in diameter, with thicknesses varying from If" to 2§" respectively. 

 Tn comparing their weight with those of earthenware pipes, it is 

 found that they are slightly lighter, an earthenware pipe of 

 2" diameter weighing 2cwt. lqr. 211b., while a pipe of the former 

 description, of similar length and diameter, weighs only 2cwt. lqr. 

 The simplest form of jointing is made by butting the pipes, and 

 placing outside a bandage netting embedded in cement-mortar ; 

 other joints are also used to suit circumstances. 



Large numbers of these pipes have already been used in 

 New South Wales.
