It is the latter, certainly; I was going to explain that. It is the commercial fertilizer, which sells from $40 to $42 a ton, according to the quality. The commercial fertilizer is composed of slag as a base, and around that or through it and with it are the real fertilizing elements, four parts ammonia, six parts phosphorus and ten parts potash. That is the general formula.
Hon. GEO. E. FOSTER: I would ask the hon. member for Cape Breton whether the product turned out by the Sydney company is simply the slag ground, or is it the slag ground and mixed with the other materials, thus constituting a compound fertilizer?
