hog s dung, well rotted sheep and cow stable manure, &amp;lt;fec. In 

 Europe, malt-dust, and rape-cake, either powdered or dissolved 

 in urine are highly prized. The manure and urine of horses 

 are objectionable as giving a bad taste to the tobacco. ( Gol-

All the ingredients necessary to replace the ash of 100 Ibs. of 

 tobacco leaves, are present in the following mixture : (John 

 ston.) 



Bone dust, 15 Ibs. j Carbonate oi Soda, (dry) 5 Ibs. 



Sulphuric acid, - 8 &quot; Carbonate of Magnesia, 25 



Carbonate of Potash, (dry) 31 &quot; | Caibonate of lime, (chalk) 60 



The leaf appears to have the power of replacing a deficiency 

 of potash in the soil with lime ; while, as was before shown, the 

 soil and climate produce a great difference in the proportion of 

 the inorganic constituents, 



574. The best soil for this plant is a light sandy loam ; or a 

 light soil rich in organic matter, having a portion of sand mixed 

 with it. Clay soils are not adapted for it. New or fresh land 

 is better than old ; and pretty steep hill-sides, if light and rich, 

 are better for the production of fine tobacco, than level land. 



575. The following is the mode of culture pursued in Con 

 necticut and New York ; and in the West, north of the Ohio 

 river, (a,) A &quot; seed-bed&quot; is prepared as early in April as pos 

 sible, for which the richest and best land, moist but not wet, is 

 chosen. It is manured, dug deeply, pulverized, and rendered 

 fine and smooth ; and the seed sown broad-cast, at the rate of 

 one table-spoonful to the square rod, before the earth becomes 

 dry. After this it is raked, but thfe seed is not buried ; it is 

 rolled, or a man treads it in, rendering the surface of the bed as 

 haru as possible. Weeds must be carefully extirpated. When 

 the plants have leaves two or three inches long they are fit for 

 transplanting about the beginning of June, (b,) The field 

 intended to be planted should be well manured, and plowed at 

 least twice ; harrowed, and rolled, and left as smooth as possible.
