Infact, Director Patterson, who made the experiment, stillrecommends slaked lime for many agricultural purposes. Views of certain eminent European authorities. — Inconclusion it should be said that such eminent Europeanauthorities as Deherain in France, and Orth in Germany,though fully familiar with the dangers which may arisefrom the unintelligent and inordinate use of burned orslaked lime, nevertheless, recognize the great agriculturalvalue of these forms of lime in specific cases, when used in. No lime Lime as top-dressing in Lime harrowed in spring after seeding before seeding Fig. 35. — Timothy. All Seeded the Same Autumn. The lime in both cases was from the same lot, and was weighed out at the same time. reasonable amounts, and under ordinary conditions ofculture. 441. The penetration of lime into soils. — One of theusual recommendations regarding lime is to harrow itinto the surface of the soil, for the reason that it tends towork downward. There can be no doubt but that thevarious forms of lime will be carried downward to a con-siderable extent both by mechanical washing and in solu-tion as bicarbonate and otherwise, especially in soilswhich are sandy and open, and which are relatively de-ficient in vegetable matter.
