Washingtons greatest contribution to the nitrogeiio\is fer-tilizer su[)plv is in the form of dried and treated fish scrap or. eutl-lisli plant. fish guano. The greatest part of this guano is supplied byth<; whaling companies. One company was formed for the pur-pose of working up dog fish and other worthless fisli. The Pacific Products Company of Seattle and Port Town-send is working up the worthless fish as well as salmon canneryuaste. Appioximately 1,000 tons of prepared fish fertilizer istlieii annual output. Three and tons raw fish makeone ton fertilizer, this containing approximately 11 per cent ni-tiogeii and 14 per cent bone phosphate. For years the salmon canneries threw away a trcinendoustonnage of scrap—some 40 or 50 })er cent of the weight of the 16!^ Manufacturing Opportunities in Washington fish—liuads, fins, viscera, etc. Nowadays, much of this scrap issaved and, when properly treated, forms a very fine fertilizermaterial containing both nitrogen and phosphorus.
