Allusion must be made, however, to two interesting papers by Prof. Henry O. Forbes, which will be cited and quoted in a proper connection on a later page.3 Peruvian guano is indirectly but obviously a product of fish.The birds in this case fulfil a function comparable to that of the American factories that convert flsh into fertilizer.The operation of the birds may in some respects be relatively wasteful, but the product yielded by them has the virtue of being in a form more readily available to the growing crops.NO.
