thermometer on one of the lower tiers, near the center. Start your fires so as 

 to produce a uniform heat of about ninety degrees, Fahrenheit, and continue 

 this temperature until the tobacco becomes sufficiently yellow. 



Xo exact time can be given for yellowing, as tobacco which contains a 

 superabundance of sap, or is very large, requires more time than that which is 

 smaller or has less sap. 



An ordinary crop will require from twenty-four to thirty-six hours. Do not 

 allow it to become real bright yellow before raising the heat, as it continues to 

 yellow for several hours after. 



Xow raise the heat three degrees per hour until you arrive at a temperature 

 of one hundred and ten degrees, and remain at this point until the ends of the 

 leaves curl slightly; after which continue to advance at the same rate as before 

 [three degrees per hour) until you arrive at one hundred and twenty. To pre- 

 vent "sweating" during this time, the safest plan that can be adopted is to 

 keep the door open It is not necessary to keep it wide open, though there is 

 no objection to its remaining so, except that it requires more fuel to secure the 

 heat desired. At the beginning of the season, in curing the first tobacco in 

 each barn, or in curing heavy or green tobacco, this plan should invariably be 

 adopted, otherwise the dampness will endanger-its injury from sweating. 



Having arrived at one hundred and 'twenty, the door should now be closed : 

 and, under favorable circumstances, may be closed at the start, but must be 

 opened often while advancing from ninety-five to one hundred and ten degrees. 



If sweating commences (which maybe known by the leaves becoming damp 

 and pliable) raise the heat and open the door, for the purpose of creating a 

 current of hot air, which will soon cause it to disappear. 



The leaf should now be cured before arriving at a temperature of one 

 hundred and thirty; therefore advance only at the rate of two & ' hour 



for the next five hours. Then, in curing the stem, raise the heat five degrees 

 per hour until you arrive at a temperature of from one hundred and sixty-five 

 to one hundred and seventy-five degrees. By this time the stems should be 

 thoroughly cured; but if not, go no higher, but continue the heat, at the high- 

 est point reached, until they are. 



We condense the instructions for regulating the heat in the form of a table 

 lor reference : 



Remain at 90 until sufficiently yellow. 

 Advance from 90 to 120 , 3 per hour.
