IMPROVEMENTS IN STEEL MANUFACTURES. 73 



being at the same time produced. Unfortunately for the 

 success of this invention, its adoption necessitates an almost 

 entire change in the present plant of steel-works, the process 

 being a complete revolution in the manufacture. One or two of 

 the leading firms in Sheffield have been sounded as to the en- 

 couragement it would be likely to receive, but their 

 opinion is that the objection mentioned would be an 

 insurmountable obstacle to its adoption. Time will prove 

 whether they are entirely correct in this supposition ; but 

 as matters stand in connection with the steel trade, especially 

 the competition and quality of goods put out by American 

 manufacturers, we are of opinion that some move must soon 

 be made, or English steel manufacturers will find their 

 occupation gone. There are numerous other inventions of 

 practical utility for which the public are indebted to Mr. 

 Boyle, but we have no space in these pages to refer to them. 

 Our main object is to assist in the progress of practical 

 sanitation by doing full justice to Mr. Boyle's inventions for 

 that purpose.
