This method of utilizing chlorine fui-nshes a verysatisfactory solution to the problem of the over-pro-duction ofchloriiie. In liis book EId<](TROLYTICSODA (La Sonde Electrolytique) A. states(page 9), When electrolytic soda was first pi-nposed,. FiK. 6—MicrophotoKraph ol hciiii) .staUt pulp. the question immediately arose what will be done withthe chlorine?; and on page 11, But if the ammoniaprocess has been able to compete for so long with theLeblanc process in spite of the fact it was not helpedout by chlorine, the electrolytic process does not seemto be in the same jx)sition, at least at present, and itis necessary that chlorine, in some form or other,should bear its share and help to maintain the electrolytic chlorine can be produced at a reasonablecost and find a ready market, electrolytic soda will bein a position to compete with Leblanc soda and withSolvay soda. The most impnrtant cbbirine ciinipdund. from a i-om-mercial point of view, is bleaching powder or chlorideof lime. But the demand for this product is not suf-ficiently great t-o absorb all the overprodxiction ofchlorine nor to raise the sale price. In the book alreadymentioned, Montessus de Ballore (page 76) says
