Not illustrated. 1887 edition. Excerpt: contaminated with iron and alumina compounds. The Navassa phosphate also, from an island on the coast of Hayti, which has been a good deal used in this country, is much contaminated with the harmful alumina and iron compounds, although it is often rich in phosphates. It contains sometimes as much as 30 to 35% of phosphoric acid. Eedonda phosphate contains from 20 to 38% of phosphoric acid, or as much as would amount to from 42 to 84% of phosphate of lime, though in reality there is but little lime in this material, the phosphoric acid being combined with alumina. Mejillones guano contains some 05 to 75% of phosphate of lime, and nearly one per cent of nitrogen, and that from Patagonia some 20 or 30% of phosphates and 4.',% of nitrogen. Curaoa guano contains 65 to 73% of phosphates. Pfwsphatic Guanos. It may be said of all the phosphatic guanos which have been formed from bird dung in rainy regions, that, although the nitrogen compounds and the potash of the original dung have been almost completely washed away, the phosphate itself is in a very different state from that in many of the rock phosphates proper, such as Canadian apatite, for example. Much of the phosphoric acid in the phosphatic guanos could be dissolved tolerably easily by plant roots, and by carbonic-acid water in the soil. There can be no question that the phosphatic guanos, used as a fine powder, might be applied directly to the land in many situations. Most of them would probably do as good service as bone-black or bone-ash, or evon better, on soils rich in humus, such as reclaimed bogs, or on cranberry beds or moist grass lands, or even for turnip and buckwheat fields. The powdered material might be incorporated with composts also, or with manure when the heaps are...
