12 REMARKS UTON GROWING SEEDLING CALCEOLARIAS. 



I have used this stove best part of last winter, and at this season 

 have had t occasion to light it but four times ; therefore improvements 

 may, possibly, yet suggest themselves ; but in the neighbouring town 

 of Weymouth, it has been tried two winters and found successful. I 

 feel sanguine that this improved application of fire-heat will be found 

 considerably more economical, and of much easier management, than 

 the old plan, particularly when this adoption of the," new principle 

 attracts the attention of scientific persons ; and that the result will be 

 a considerable augmentation of the number of greenhouses, and an 

 increased encouragement of floriculture. 



If the principle of the Arnott stove were applied to the present 

 fire-places for warming greenhouses, I think it would prove to be 

 more economical than the old plan ; but if not so, there would cer- 

 tainly be a great advantage in very severe weather, from the length 

 of time the fire will continue without being looked to, in consequence 

 of the regulation of combustion, particularly with a self-acting 

 valve.

REMARKS UPON GROWING SEEDLING CALCEOLARIAS. 



BY AN AMATEUR OK EDINBURGH. 



In offering the following remarks upon the culture of seedling Cal- 

 ceolarias to prove them, I shall not premise the few hints with any 

 eulogy upon the beauty of the plant, as it is so well known and so 

 universally admired, not only for its long-continued season of flower- 

 ing, but also for the now endless variety of colours that it presents 

 through all the shades of white, yellow, and crimson, to the strange 

 admixture of hues in the beautifully unique Chandlerii. 



For some years past I have raised plants from hybridized seed 

 gathered off the best varieties among a good collection of them in my 

 greenhouse. As the plants ripen their seeds most freely under the 

 protection of glass, I get an abundance of fine, well-ripened pods, 

 containing quantities of good brown seed ; these seeds I sow in pans 

 about the end of July or beginning of August, and then place the 

 pans in a gentle heat, always giving plenty of air whenever the 

 weather permits. In a short time the seeds begin to germinate, and 

 innumerable small plants make their appearance. At this stage of
