low preparations for it that can be devised ; and is prob- 

 ably the cheapest and most convenient process to res- 

 tore an exhausted soil. At the same time it should be 

 considered, that gypsum acts more powerfully on soils 

 thus prepared. 



Gypsum There is not any manure concerning which 



the reports of experimenters have been so contradicto- 

 ry as in the case of plaster of Paris. Its advantages are un- 

 doubtedly great. Plaster is more useful on dry than oa 

 wet soils, particularly on gravelly or sandy loams, and in 

 some measure prevents the effects of drought. Its dis- 

 covery has almost doubled the value of land in certain 

 places. It is supposed to be useful on drained clayey 

 soils, preventing their baking. It seems probable also, 

 that it is best fOrland in a state of sward, though it is 

 usefully employed on others. 



The following are the conclusions of Chancellor Liv- 

 ingston and Mr. Logan after various trials. That there 

 is no difference between European and American gyp- 

 sum. It acts as an immediate manure to grass. One 

 dressing will continue in force for several succeeding 

 crops. It does not produce any remarkable effects used 

 as a top dressing for grain. On stiff clays the increase 

 of vegetation will not pay the expense of the m.anure. 

 It is uniformly beneficial to Indian corn, unless in very 

 rich or very wet lands. Beneficial to flax on dry, poor, 

 sandy land. Particularly adapted to the growth of clo- 

 ver in all dry soils, or even in wet soils in a dry sea- 

 son. That it has no effect in the vicinity of the sea — 

 but from the successful use of planter near the sea 

 coast in the state of Maine, on Long Island, and near 

 the salt water in this state, by Mr. Moses Brown, the 

 editors unite in opinion, with many others, that its ope- 

 ration depends more on the nature of the soil, or quali- 

 ty of the article, than on the state of the atmosphere, 

 contiguous to the sea coast. 



Gypsum generally benefits all broad leaved plants — 

 such as corn, potatoes, peas, clover and most of the 

 grasses. It is also good for young fruit trees. On gras- 

 ses, the best time to sow it is when vegetation starts in 

 the spring, at the rate of 1 bushel per acre, and the same 

 quantity immediately^ after haying. On corn and pota- 

 toes, it is generally applied to the growing plant j oth-
