The following is taken from the seventh of a series of articles bv J. PI. Hart, , on Caean, which are appearing in the West India, Circulur. Reference lo these articles has been made already cm pages 260 and 292 of the present voUiine of the Af/ri- cidtural News:— The application of manure is a .suliject upon which chemists and vegetable physiologists difl'er in many respects. The chemist is apt to insist upon the manure being buried beneath the .soil, or, he says, inuch nf its value will be lost owing to the dispersion of its volatile properties by moving air ; but the cultivator may easily ascertain the best method of applying manures of all kinds, if he studies the life history and character of the plant, and the nature and morphology of its organs of assimilation; and moreover, the frequent showers of the tropics prevent any great waste of the volatile constituents, unless they come -so heavy as to them away. The destruction of roots which the operation of burying manure occasions, would, in most instances, completely nullify the action of the manure applied, as the broken roots would not have the power, or the same amount of surface for absorbing food, as when uninjured; and the manure applied, through its coming into direct contact with injured tissue, would tend to destroy the roots by its caustic character, rather than to be absorbed by them. That beneficial results follow the application of manure when buried beneath the surface, is, of course, patent to the novice, but in the case of surface-feeding plants, it is only afti-r the roots have recovered from the injuries done by the digging, that they arc able to take up any manure which has been applied when these organs are again in a condition to pciform their proper functions. Even granting that no s[)ecial harm is done
