are not to be fed with creosote from the main tank, but from 

 a small tank in which a gauge shall be placed, to measure the 

 quantity taken up by the sleepers. 



"A gauge shall also be fixed on the highest point of the 

 creosoting-chamber, to ensure that the chamber is quite full 

 before the pressure-pumps begin to work. The sleepers in the 

 creosote-chamber shall be laid parallel, with one inch spaces all 

 round, the spaces being kept by pieces of wood or iron. 



" The creosoting-chamber and tanks shall be kept perfectly 

 clean and free from muddy sediment at all times."
