wi ek, some fresh air may be admitted daily. Straw mats should be used at 

 night. The mats will also be found useful in shading the plants in hotbeds 

 and cold-frames. 



Plants should be hardened as much as possible before they are taken 

 from the frames to the field. This is accomplished by gradually subjecting 

 them to fresh air and by not watering more than is absolutely necessary. 

 The latter factor is more important than fresh air and low temperatures.
