CHAPTER VI. 



TEMPERATURE CONDITIONS AND VENTILATION. 



The violet must be kept cool and any attempt 

 to force it by heat will prove disastrous. For 

 Campbell violets an effort should be made to keep 

 the night temperature between forty-five and 

 fifty degrees, with a day temperature, in bright 

 weather, ten to fifteen degrees higher. Marie 

 Louise should be kept cooler, say forty to forty- 

 five at night, with day temperature fifty-five to 

 sixty. 



When the weather is cloudy and cold do not 

 attempt to keep the inside temperature in the 

 sixties or even the fifties. Probably the safest 

 rule to follow with the violet at all times is to 

 manage the conditions so as to have, as near as 

 possible, an average temperature of eight or ten 

 degrees above freezing. For example, if the 

 temperature outside is thirty degrees above zero 

 in the day time and the weather cloudy, keep 

 the temperature of the houses not more than 

 forty to forty-five degrees. If sunny weathei 

 prevails the temperature will naturally go higher, 

 but do not allow it to get above sixty degrees, ii 

 it can be avoided by ventilation and allowing the
