gives better results than open-tank treatment. A long list of antiseptics 

 was used, including oils, tars, and salts. The latter are liable to leach 

 out during the rainy season. "Cheap creosote of good quality is at the 

 basis of the whole question, and so long as India has to import all its 

 wants, so long will the treatment of sleepers be handicapped." 



Duration tests have been conducted in six groups of antiseptics, and 

 the average life of imtreated and treated sleepers is stated. "Review- 

 ing the results of all six groups of laboratory experiments, it may be 

 stated, generally, that the hard and moderately hard woods treated, as 

 compared with untreated specimens, have fared, in proportion, better 

 than the softwoods. The results obtained with Powellized tim1)er are 

 fairly satisfactory, but the outstanding feature of the experiments is the 

 superior results obtained with the various coal-tar creosote products as 

 compared with salt solutions."
