HOTBEDS AND COLD-FRAMES 



prevent the formation of frost on the glass. 

 If you find, in the morning, that the glass is 

 covered with moisture on its under side, 

 raise the sash a trifle and leave it so until the 

 moisture clears away. 



If at any time you have reason to think 

 that the warmth inside the frame is decreas- 

 ing too rapidly, bank up about it with fresh 

 fermenting material. 



After constructing the hotbed and put- 

 ting the frame and sash in place, test the 

 heat inside by an accurate thermometer 

 before venturing to sow any seed. When 

 it registers 85^ or 90"^ the bed is ready for 

 seeding. 



In making the frame for a hotbed care 

 should be taken to see that all joints fit snug- 

 ly. A great deal of cold can be admitted 

 through a very small crevice. A few cracks 

 will let out the heat faster than it is generated, 

 therefore see to it that in constructing the 

 frame a good piece of work is done. 



Some persons tell me that they always 

 bank up a hotbed with earth. This enables 

 it to retain the heat better than it is possible 

 for it to do without banking. 



A hotbed will be of no particular benefit 



unless supplemented by a cold-frame. This 



is simply a snug inclosure of boards covered
