Analogy between this action of lime and that of wood-ashes. Quantity of lime to be applied. Effects of an overdose. Form in which it may be most prudently used. When it ought to he applied in reference to the season--to the rotation--and to the application of manure. Its general and special effects on different soils and crops. Circumstances which inlluence its aciion. Length of lime during which its effects sre perceptible. Theory of the anion of lime. Necessity and nature of the exhaustion which it sometimes produces. Sinking of lime Into (he soil. Why the application of lime must be repealed. Action of lime on living animals and vegetables. Suggestions of theory. Use of silicate of lime. Having explained to you the aciion of the most important saline and mixed mineral substances which are or may be beneficially applied to the soil, I have now to draw your attention to the use of lime--the most valuable and the most extensively used of all the mineral substances that have ever been made available in practical agriculture. It has, and with much reason, been called " the basis of all good husbandry"--it well deserves, therefore, your most serious attention as practical men, and on my part the application of every chemical light by which its usefulness1 may be explained and your practice guided.
