Discussion. 



Warren "\Y. Rawson said he had Hstened to the lecture with a 

 good deal of interest and had no exceptions to take in the descrip- 

 tions given for the management of a private house. 



For the treatment of a commercial house, however, other methods 

 are preferable; the houses should be from 40 to 50 feet in width; 

 steam is better than hot water for heating; and we have done awav 

 with benches, the crops being grown on the ground. The lecturer 

 had given the results of his own experience, which showed that 

 different conditions required different regulations in the successful 

 growing of crops under glass. 



George D. ]Moore asked the lecturer if he had had experience in 

 the use of nitrate of soda in his house. He had used it and it was 

 of value in freshening the foliage. He also inquired concerning the 

 red spider which he had found a serious pest and that spraying 

 did not have any effect on it. 



Mr. Turner replied that nitrate of soda used with other fertilizers 

 and farmyard manure is of much benefit especially in hastening 

 crops along. 



As to the red spider if it gets much headway it is almost impossible 

 to stop it and you might as well throw out the entire crop at once, 

 and change the soil in the house, and plant over again. By close 

 watching and spraying he had experienced no trouble in keeping 

 it in check. 



Duncan Finlayson inquired why the lecturer had left out peas 

 and spinach, especially on a private place where expense was no 

 object. 



]Mr. Turner answered that to grow these would require a house 

 as big as a farm. 



^Yilliam X. Craig said he had recently seen a fine crop of peas 

 growing in a house and had noticed also a bench of the New Zealand 

 spinach which was the most profitable variety for greenhouse 

 cultivation. He would like to hear something about the culture 

 of asparagus and mushrooms under glass. 



Mr. Turner stated regarding asparagus that he had grown it on 

 and off but had dropped it entirely. It grew too spindling to b?
