DISCUSSION. 



A Lady : What do you use for a fertilizer ? 



Mr. Nagel: We use rich soil in the summer, and a little be- 

 fore they set buds we use liquid manure, cow manure in water. 



A Lady: They bloom about six months from the seed ? 



Mr. Nagel: Not quite six months. They bloom the same 

 time as the other chrysanthemums. 



A Lady: How long does it take the seed to germinate ? 



Mr. Nagel: About three weeks. 



SHAPE OF GREENHOUSE ROOF. 



JOHN XORDIXE, LAKE CITY. 



In regard to the question of the advantage and disadvantage of 

 building a greenhouse with the short span to the south, I would say 

 this, that in a greenhouse for growing roses for cut flowers, I would 

 prefer the long span towards the south for two reasons: First, when 

 the roses have grown to the height of between three or four feet, 

 which they will do by the first of Janviary, they will make too much 

 shade for the plants which are placed on the broad bench that is 

 always located on the broad span side of the greenhouse, and during 

 the winter the sun never rises high enough to shine over the apex 

 of the greenhouse; this will leave about one-fourth of the room in 

 the house in the shade. The second reason I find is that a green- 

 house with the short span towards the south does not need as much 

 watering as another, consequently, the daily spraying of roses can- 

 not be performed in such a house with as good advantage, and dur- 

 ing cold w^eather there is more surface of glass covered with ice 

 which shuts out the light that is so much needed during the dark 

 part of the 3'ear. But, for a propagating house I should just as soon 

 take one with the short span to the south, because in this house you 

 will have no high plants to shade each other, and in this house you 

 can more easily keep the low temperature which is required for the 

 propagation of most of the plants; and 3'ou do not need to use as 

 much water, because there is not as large surface of glass exposed 

 to the sun. 



In regard to heating there is little difference, although I am in- 

 clined to think it would require less heat in a house with the long 

 span to the south.
