Corrugated Inverted Siphon 



Replacing a steel syphon which had rusted to failure. 



<I Since it has come to be generally admitted that iron resists cor- 

 rosion in proportion to its purity, the results of chemical analysis have 

 assumed a great importance. Analyses of iron and steel samples by the 

 carbon method (pencil, paper and carbon) may eliminate, at very low 

 cost, the most stubborn of impurities and establish wonderfully high stand- 

 ards. The methods of well equipped laboratories are somewhat different. 

 These show today what they have been showing for years Arco-American 

 Ingot Iron is the purest on the market.
