that the transportation would be li^ht. The latter is 

 better adapted to sandy or slightly loamy soils ; but is 

 good for any soils not already abounding in potash. 



As tobacco requires much alkali, the soil should be 

 supplied with this in the form of lime, potash, soda, and 

 ammonia. All those are contained in well-preserved 

 barn manure. Ammonia, as all know, abounds in Peru- 

 vian guano and in all barn manure not half spoiled by 

 mismanagement. Lime may be most cheaply supplied 

 from the gas-house, only it must not be applied in a fresh 

 or hot state immediately before planting tobacco or any 

 other crop. A small dressing of common salt, not more 

 at one time than five or six bushels to the acre, will sup- 

 ply all the soda required. That a soil for tobacco should 

 contain lime is important ; and the spent ashes from the 

 soap boilers are perhaps, the next cheapest way of sup- 

 plying it, after that before named — the waste lime from 

 the gas-house. 



In virgin soils, and in all limestone regions, that have 

 not been long cultivated, it is safe to presume that 

 there is lime enough already in the soil. But, in all 

 other cases, the farmer cannot safely presume upon there 

 being lime enough in his soil for a large crop of tobacco 

 and then a large crop of wheat to follow, unless he has 

 put it there ; and will do well to apply it in some form, 

 as gas lime, leached ashes, or a pretty large dressing 

 of the superphosphate. 



Since writing the above the following facts have 

 come to our knowledge : Some years ago, Joseph Har- 

 ris, Esq., editor of the Genesee Farmer, published an 

 essay on the phosphates, in which he stated, as proba- 

 ble (did not know by actual experiment, but thought) 

 that superphos^jhates of lime, if tried, would be found to
